Acumen Energy Impact Report

We’ve just launched the Acumen Energy Impact Report. It is the culmination of more than 10 years investing in early-stage, off-grid energy companies in South Asia and Sub-Saharan Africa, and more than four years of developing Lean Data, our approach to measuring social impact that’s built on the simple premise that talking directly to customers is the best way to build successful companies that make a meaningful impact in people’s lives.

The headlines are exciting: the $22 million we’ve invested in 20 companies has allowed more than 80 million people to have access to safe light, power, and cooking fuels. Three-quarters of these people—58 million of them—have access to modern energy for the first time.

Think about that for a minute.

$1 invested means three people can, for the first time, move away from dirty, dangerous, and expensive fuels like kerosene. Three people can turn on a light that costs nothing to charge. Three people can feel safer at night. All for a dollar.

But everything I just wrote, about what it means to have access to that light—is it really true? How can we know for sure?

It’s simple. We know by asking them.

At its most basic level, this is what we do with Lean Data. It sounds simple, but if we’d written this report five years ago, and you’d asked us the following questions, here’s what we’d have said:

Who exactly are these 80 million customers?  We don’t know.

Are they men or women? Rich or poor? We don’t know.

Do they really stop spending money on kerosene? How much? We don’t know.

Does financing create more access? Or more debt? We don’t know.

Do they use the light to run a business? To study more? We don’t know.

What about cookstoves…do they really get used? How often? We don’t know.

Do these answers differ for different countries, different customers, different types of business models? You guessed it, we don’t know.

OK, I’m overstating, but only a little bit. We’d know something thanks to the customers we’d visit in person. We’d have anecdotes from the companies in Board meetings. We would talk to management and to the sales team and learn from them.

But the simple truth is, the amount of educated guesswork was enormous.

The “impact math” you’d have found from us then, and which is still prevalent today in much of the impact investing sector, assumed that every customer in every place was more or less the same. It assumed that every product, no matter who it was sold to and where they lived, had the same impact.

And the thing is, those assumptions were often way off.

This isn’t just important in terms of how we learn, or in terms of how we deploy capital to solutions that make more of a difference, or even in terms of how we serve our companies better.

It’s important to the customers themselves. Really important.

If you’re the person buying a stove, and you still have to collect wood or charcoal for your other stove, it matters, because you’re still wasting time and money and your home is full of smoke.

If you’re the mother who saves up for a solar panel on her roof, only to discover three months later that the panel doesn’t work when it rains, it matters because you’re in debt and your home is still dark.

If you’re a customer off the grid and, despite tens of millions of new investment in off-grid companies, you’ll still be in the dark five years from now, it matters to you.

And if it turns out that certain products are bright enough, durable enough, and flexible enough that they make it easier to start and run a business, and if that helps more shops stay open later so more customers can make more money, and local economies can grow, that matters a lot too.

These are the questions we are starting to be able answer thanks to Lean Data—because we talk directly to customers (more than 5,500 of them, in this case, twice for each customer), we hear what they have to say, we learn about their lived experience and can use that to help our companies serve them better.

Some of those stories are here in this report: data on who the customers are, whether they save money, if they feel safer, if their homes are less smoky. With all this data at our fingertips, we begin to understand which companies have the most impact, which companies reach deepest into low-income markets, where there are trade-offs between financial and social returns.

Giving these customers voice to tell us what is actually happening in their lives, rather than just assuming that we know, is the first step towards real understanding. It’s the first step towards dialogue. It’s the first step towards holding ourselves accountable to the promises we make and the claims we share.

I don’t make a habit of reading nonprofit annual reports, and you probably don’t either, but this one is different. I hope you’ll check it out: bit.ly/EnergyImpactReport

Uncorrelated Impact Understanding

Not long ago, I was speaking to a group of sophisticated impact investors from across the spectrum: everything from fully liquid, market-beating financial return expectations to market builders focused on creating social impact who are open to a broader range of financial returns.

The focus of my talk was Acumen’s work on Lean Data, which is our industry-leading approach to gathering customer data at scale. We’re cracking the nut on using technology to give voice to tens of thousands of customers in ways that allow companies to serve them better. I believe that this will, over time, help the sector as a whole deploy more capital to more opportunities that have more social impact. It’s exciting.

But before digging in to the details of Lean Data, I started the talk with an assertion:

The seriousness with which you work to understand impact should be uncorrelated with your expectations around financial return.

I actually said this twice, because we’re so used to talking about correlations (positive or negative) between social impact and financial returns that I wanted to be very clear what I was, and was not, talking about.

My point is, if you say you are in the business of creating impact, then, irrespective of the instrument you use, the financial returns you expect, and the risk you’re willing to take, you’ve got to be serious about understanding impact.

Interestingly, I heard some resistance on this point. The resistance mostly took the form of “I know impact when I see it” or, “why would I waste time on this, it will just distract me from doing the real work?”

I believe there are some cases in which we really understand impact, but I believe those are the exception. Indeed we are so quick to say “we know enough” in a world in which we know shockingly little.

For example, take the $800 billion spent annually by the U.S. government. Peter Orszag, and Jim Nussle, who successively ran the U.S. Office of Management and Budget, write in Moneyball for Government that “Less than one dollar out of every $100 the federal government spends is backed by even the most basic evidence that money is being spent wisely.”

Less than $8 billion of the $800 billion spent annually by the U.S. government is backed “by even the most basic evidence?” Wow. Color me unpersuaded by the argument that we generally know enough.

I think what’s really going on is that we:

Overestimate how much we know

Overestimate the cost of getting great data – because approaches that came before Lean Data typically cost 100x as much

Create an artificial distinction between “creating customer value” and “creating social impact”

Assume that, no matter what anyone says, this is about marketing and dealing with funders, not about learning

Underestimate the value of what we can learn.

On top of this, I worry that we say too lightly that we’re in the business of creating social change, or we assume that this “caring about impact” stuff should be left to the folks who are on the frontiers of solving tough, challenging problems in innovative ways.

The truth is, we are quick to celebrate and advocate for more money walking through the “I (also) want to create social impact” door and then get awfully timid talking about whether that impact is getting created or, more broadly, how much we understand about the connection between the investment, the intervention and the impact it creates.

Caring about impact doesn’t mean you don’t understand how to make money. It doesn’t mean you’re not a serious investor. It doesn’t mean that you’re giving something up.

It’s simply saying: this is who I am, this is what I do. I’m in the business of creating massive positive change in the world. And I know how to do that better than anyone.

You can say all of those things and not blink for a second when someone asks you what your financial returns are going to be.

If we are in the business of change, then we have to be in the business of understanding how change happens.

Building our impact intuition

I was speaking to an impact investor recently, and he was saying that investment decisions are ultimately based on an intuitive sense the investor has about the company: the deal, the team, the market opportunity. And shouldn’t we just use our intuition to assess impact?

This is the most common unspoken premise used by impact investors to justify not collecting impact data.

So, where does this intuition come from? And is there such a thing as good and bad impact intuition?

Intuition is subconscious pattern recognition. And patterns are the sum total of the information we’ve taken in. If that information, and our ability to understand and process it, is of high quality, then we develop good intuition. If not, not.

A good investor is awash in quantitative and qualitative data that inform her investment intuition. For example, on the quantitative side, she’ll know what she expected gross margins to be, the predicted length of a company’s working capital cycle, and how many years she forecasted it would take for the company to get to profitability.

But that original financial model will have a very short shelf life: after the investment, she’ll get reams of data to show whether her predictions were right or wrong.

But in the world of impact, she’ll handle things differently.

She’ll look at research and benchmarks to develop a thesis. And she’ll stop there and multiply products sold by those benchmarks [e.g. 10 lights sold * X predicted impact/light = 10x impact].

This is like creating a pre-investment financial model of a company and then, two years later, when asked how the company is performing, using the model’s original variables to answer that question.

Not only would this answer not be any good, but her impact intuition would never improve.

Why do we accept the idea that we can understand the impact we are creating in people’s lives by looking at comparables? Why do we nod when told that it’s hard to get better data (it’s not)? How can we say that “we know impact when we see it” if we don’t gather data to understand actual performance?

The only explanation is this: we are not the people whose lives are, or are not, improved by a given intervention; we are not personally affected by a positive or negative ROI on a “better” solution; and the difference between potential and actual impact doesn’t land on our doorstep, or in our pocketbooks, or in our child’s cough or the quality of the education he receives.

The only way we’ll create better impact intuition is if we apply ourselves seriously to the question of learning what does and doesn’t improve people’s lives.

We don’t settle for “it’s too hard” anywhere else but here.

Impact measurement over the next decade

I had the chance to participate on a panel at SOCAP about the future of impact measurement, and was surprised how challenging I found Karim Harji’s framing question:

Where is impact measurement headed over the next decade? What is it going to take to get there? 

After pondering on this question for a while, I ended up at the conclusion that the future is very bright at the level of company-customer interaction.

I say this because in the coming decade, social enterprises, like all companies, will necessarily begin accessing and managing much more customer data gathered remotely through devices. It’s a bit easier to see this future when one is in San Francisco staying at an Air BnB and taking Lyfts everywhere: as mobile phones become both the communications and transaction platforms for nearly everything in everyone’s lives, companies, no matter what their specific business or the customers they serve, will have more data about us. While it’s true that poorer, more remote customers will lag millennials in San Francisco in terms of how soon they get on this conveyor belt, the direction this is heading, for everyone, is clear.

With that in mind, the only question at the company-customer intersection is whether and to what extent companies will incorporate data about social impact into their growing data flow. My thesis is that doing so will be a competitive advantage, allowing companies that move first to better understand how well their products and services are improving their customer’s lives, thereby driving greater loyalty, share of wallet, and share of mind and voice.

I believe this because, as our Acumen impact team has worked with companies on Lean Data projects, it’s become increasingly clear that value creation is impact when you’re dealing with critical goods and services like electricity or education or healthcare: if the customer who buys her first solar lamp stops using kerosene, uses the lamp to keep her business open later at night, and also uses a second lamp for her kids to study at night, then that lamp is creating deep and meaningful value (impact) for her. And all our data show that this same customer is nearly always a net promoter of the company, a source of positive word of mouth, and a high-value and loyal customer.

If this thesis plays out over time, then we’re about to be riding a huge, powerful wave that we’ll simply have to redirect slightly to incorporate thoughtful impact data capture and to drive towards impact management. Soon, even resource-strapped, impact-focused companies in the developing world will have no choice but to gather and utilize more data (including impact data) from end customers if they want to serve these customers effectively.

The question I find harder to answer, interestingly, is: What is going to happen to the capital market for impact? Here, things seem a bit muddier.

In order for capital to increasingly flow towards high-impact opportunities, there has to be some standardization in terms of how impact is measured and communicated, so that an investor looking to compare impact performance can compare opportunity A and B in the same way she compares financial performance for these same two opportunities.

I believe this evolution is a very important one, indeed it might be the most important development that needs to happen if the impact investing marketplace is to realize its full potential. However, unlike the evolution at the company-customer level, it’s less clear to me that there’s forward momentum pushing us in the right direction. It seems possible that we are due for a step-change in terms of how investors deploy capital for impact, and it seems just as possible that five or ten years from now things will be as bespoke and hard to decipher as they are today.

My best guess is that what’s needed to make a shift here is that a handful of highly influential and interconnected players – those holding large amounts of capital that they distribute through a large ecosystem of connected funders – need to establish their own higher, clearer impact measurement standards that they will use to deploy capital, such that their new standards flow all the way down the chain and slowly shift expectations for, and raise the bar for, everyone in the space. This was the role that the U.S. Government played with LEED certification through the GSA, which owns 9,600 buildings in 2,200 communities across the U.S., and I suspect it’s the pattern that needs to play out in impact investing too.

For more on this topic, here’s the link to the SOCAP16 plenary I got to do with Karim Harji, Jim Fruchterman, Kelly McCarthy, and Paul DiLeo.

Lean Data Podcast

On Monday, Tony Loyd was nice enough to include me in his great series of Social Entrepreneur podcasts. We covered a lot of topics but dug in most deeply on Lean Data, particularly on how we are using it at Acumen to amplify the voice of low-income customers so our entrepreneurs can better serve them.  It was a fun conversation.

(if you’re not seeing the embedded link click here)

 

If this kind of thing is up your alley, you might want to sign up to receive the specialized newsletter we’ve created to share hot-off-the-press insights on what we’re learning through Lean Data. We send it out once every six weeks or so, so it won’t clog your inbox, and it’s full of great stuff.

It’s called Impact Matters and you can sign up here.

 

A confluence of impact and scale

I spent last week at the annual meeting of the Global Impact Investing Network (GIIN), and I was struck by three trends that could take our sector to the next level.

The first is around taking impact seriously. The second is how different the impact measurement challenge looks depending on where you sit. The third is the acceleration of the rate at which mainstream financial capital is entering our space.

Throughout the GIIN conference, impact — the role it plays in defining our work and how to improve the quality of our impact data — was front and center in a way that I’ve not felt before. For example, one of the first panels kicking off this year’s event was on market segmentation. While segmentation is not a new topic in impact investing, the panel was titled “Market Segmentation through an Impact Lens.” The panelists — from Skopos Impact Fund, Tideline, Athena Capital Management and Omidyar — discussed their research and client-facing efforts to make sense of impact investing from the perspective of impact objectives.

This shouldn’t be brand new, but it is. An orientation to start segmentation with an impact lens runs against the natural tendency to segment investors by asset class or sector strategy, and it’s certainly a far cry from accepting that “intentionality” (as in: my intention is to make such-and-such happen with limited accountability on the data to figure out whether or not real change is happening) is a high-enough bar to set for the sector in terms of impact.

If we could pull off organizing ourselves, as impact investors, by the change we’re trying to make in the world rather than by the investing strategies we’re using to make that happen, that would be a big step forward.

Second, we need much better impact data AND we need to help people who are drowning in too much indecipherable, low-quality data.

I had the chance to participate in two panels focused squarely on advances in impact measurement. What I learned from these panels is that better impact data isn’t enough — there’s a huge desire for simplification too.

At Acumen, our Lean Data work has focused relentlessly on going directly to the low-income customers we aim to serve so we can understand what they have to say. Our objective is to improve the quality of impact data we have by scaling up our capacity to listen to the voices these customers, so we and our investees can better serve them.

While I’m convinced that this kind of listening must to be the foundation of everything we do as a sector, it’s not enough. Listening to my fellow panelists — from Goldman Sachs, Zurich Re, Abraaj Capital and Leapfrog — I heard that big institutions with large, diverse portfolios of impact investments not only desire better impact data but they also need help simplifying and clarifying the reams of impact data they already feel they receive.

Ironically, these large institutions have too much data coming in and most of it’s not very good. Our job is both to improve the strength of the signal and also lessen the noise.

Lastly, it was impossible not to notice that more and more big-name financial players are coming to the table.

The simple fact of having an impact measurement conversation between Acumen and Leapfrog on the one hand (two organizations that are essentially growing startups, with between $100M and $1B in capital under management), and Goldman Sachs, Zurich Re and Abraaj Capital on the other means that there are innovations in impact management happening across the spectrum of impact capital. That’s hugely positive.

Then, at the end of the day, we got to hear Former Governor Deval Patrick and Deborah Winshel discuss the impact investing strategies they began implementing in the last year at Bain Capital and Blackrock. Both articulated their goals to fully integrate impact into the global practices of these uber-blue chip firms, firms that collectively represent more than $4.5 trillion in assets. While it’s early in the journey for both Bain and Blackrock, it’s clear that their actions could have a huge influence with other mainstream financial players and beyond.

As I left the conference and made my way back to New York, I was struck with the feeling that we are entering a new phase in our sector. Having passed through the teething pains of our early days and our loud, sometimes impulsive childhood, we’re ready to start growing up a bit. This means harnessing — rather than just shouting about — the increased momentum building in our space, thanks to the entrance of major new players, while also taking a much more sober and serious look at the ultimate goal of this work, which is to make a real, large-scale and lasting difference in the well-being of people and the planet.

If, in this next chapter, we can find a way to have impact investing go deeper on impact and bigger in terms of scale and reach, we will truly be in a position to take this work to the next level.

What’s in a Question?

This post originally appeared on Medium.  I’ll keep reposting these on my blog from time to time. If you want to learn more about Lean Data, check out the full story in this Stanford Social Innovation Review Article.  And there’s still one week to sign up for the free +Acumen Lean Data course.  It’s a great thing to do with a team.

Every day, more than 5 million new cellphones are sold. That’s more than 10 times the number of babies born each day. We are barreling towards a world where a cellphone will be in every pocket by 2020, and a smartphone in every pocket soon after that.

This revolution is making the unimaginable real— in the near future, we will have the opportunity to start a dialogue with literally every person on the planet. This new two-way conversation, where everyone participates, will pull billions of people into the mainstream by connecting them with one another.

At Acumen, we see inexpensive cellphones in the hands of a billion new low-income customers as a chance to supercharge the work we’re doing to end poverty. Through our Lean Data initiative, we are taking advantage of the spread of cellphones to talk to previously excluded segments of society. The focus of Lean Data is to equip startup social enterprises in the developing world with the tools and techniques to start a dialogue with their customers. Our aim is to empower these customers to articulate what they need to improve their lives.

Since starting this work in 2014, one of the most important lessons we’ve learned is that a cellphone in every pocket is just a starting point. The art of every Lean Data project is in the questions we ask. Ask the wrong questions, and you get back little of value. Ask the right ones, and you can move from data to information to actionable insights.

Great questions connect with customers and give them an opportunity to share their voice. But crafting a great question is no easy task. The slightest shifts in word choice can affect understanding; the smallest differences in intonation alter perceptions of sincerity. All of these nuances can bias the data and diminish its value.

For example, in trying to understand the usage of solar home systems in Kenya, we started with the question, “How often are you currently using (product/service)?” After testing this question over SMS, we received feedback suggesting we omit the word “often” and make the question more simple and direct. We quickly amended the question to “When do you use (product/service)?,” provided sample multiple choice replies, and received a higher level of understanding.

Getting questions right is not a new idea. Indeed, Angus Deaton’s recent Nobel Prize was largely the result of his foundational work on designing household surveys. What’s new is trying to gather rich data over a cellphone. While you can run an effective focus group with a loose guide of topics and you can cover a lot of ground in a 90-minute one-on-one interview, a typical SMS survey is limited to 10 questions and 150 characters per question. These constraints are a powerful pressure-cooker for the questions we ask. We’ve got to make every word and every question count.

So what makes a great question?

For us, a great question is one that is easily and consistently understood by customers. It’s one that makes the complex simple. And it’s one that yields insight around what matters to the customer and the social enterprise trying to serve them.

One of the biggest challenges in impact measurement and international development is understanding not just the breadth but the depth of impact. In Acumen’s case, depth is defined by the degree of change in their well-being a customer experiences from one of our investments’ products or services. For example, we know that a solar light is a better solution than a kerosene lamp, but exactly how much better and why is tricky to figure out. This isn’t an academic exercise for Acumen or our companies. Ultimately, we need to understand our customers’ needs to know where to direct our capital to drive the greatest impact, and without impact data we are simply flying blind.

Because we work across multiple sectors addressing a number of the problems of poverty, our challenge extends beyond just figuring out the quantitative impact of owning a solar light or sending a child to a low-cost private school. Our goal is to go one step further and understand the qualitative difference in value that our customers experience when comparing the various products and services available to them.

Can we really compare the impact of a year of schooling to owning a solar home system? We’re not sure, but we think it’s worth a shot. We believe that trying to understand these comparisons from a customer’s perspective will push us to listen harder and deeper, and it will test the limits of our ability to get rich data through mobile phones.

We asked ourselves if we could create a question or a set of questions that get at this topic directly, helping our customers share what they value most and why.

 

While a single question to cut through the complexity of our work seemed far-fetched, we knew that similar attempts have been made before. Twelve years ago, Frederick F. Reichheld, Rob Markey and Bain & Company developed the Net Promoter Score® (NPS). According to the Harvard Business Review, the NPS “substitut[ed] a single question for the complex black box of the typical customer satisfaction survey.” Today, it’s become widely adopted by the Fortune 500 as one of the most effective ways to measure customer loyalty. Just as NPS provides companies with a method to effectively judge performance and generate qualitative customer feedback, we wanted to create a single, unifying question to compare social impact.

Photo by Joanne Schneider

We started by asking ourselves whether the NPS question — “How likely is it that you would recommend [product/service] to a friend or colleague?” [1–10 scale]” — could serve as a good proxy for how much impact a product had for our customers. We wanted to test this by asking NPS questions together with our depth of impact questions to see if products with a higher NPS also had a higher depth of impact.

We piloted this approach in Kenya and India in two surveys, and the initial results were not as promising as we had hoped.

Despite the proven success of NPS with more affluent, educated customers, the question didn’t seem to perform well with our customers who are typically poor, have limited formal education and little experience with surveys. In follow-up conversations, we heard that the 0–10 scale was hard for them to understand and the hypothetical “would recommend” language didn’t translate well.

Lean Data surveys are short and inexpensive to conduct, so it’s easy to test and refine questions. We experimented with four different versions of the question before landing on a question, inspired by NPS, that seems to perform well: “Have you ever recommended product/service to a friend?” We also played with three different answer scales and arrived at a workable solution. Instead of a 0–10 scale, customers choose between three responses: “Yes, I’ve told many friends;” “Yes I’ve told some friends;” or “No, I have not.”

Once we saw the effectiveness of this question, we wanted to go further, to learn not only whether or not customers recommended a product but also the drivers of meaningfulness of that impact. Drawing on the concept of Constituent Voice developed by Keystone Accountability, we developed a second question, asking customers to respond from “strongly agree” to “strongly disagree” to the statement: “There have been changes in my home because of (product/service).”

In the early tests we’ve run, we’ve seen correlation between reported depth of impact and the strength of agreement to this “meaningfulness” question. For example, owners of solar lights who “strongly agree” with the statement reported an 83 percent reduction in expenditure kerosene, while the customers who said “agree” only reported a 69 percent savings on kerosene. These are just preliminary results, but we’re starting to see that this question might allow us to compare across different interventions, so that customers can tell us what they value the most and why.

While we’re still fine-tuning both of these questions, the progress we’ve made is exciting. Low-income customers are enthusiastic to engage in dialogue, and we are seeing that it’s possible — if you work at it — to develop new questions that capture rich, meaningful data about the wants and preferences of this emerging set of customers. At the end of one of our surveys, one happy customer expressed her satisfaction with the service she received at a health clinic and then added, “I really enjoyed being interviewed.” Clearly, we’re on to something.

These are the kinds of customers whose voices we aim to hear. Our Lean Data work is focused squarely on helping the startup social enterprises we invest in to listen more actively to the low-income customers they serve. For them, Lean Data is a chance to talk to their often remote and dispersed customer base in a way that doesn’t break the bank.

While Lean Data is, today, being used mostly by startup social enterprises, our work in learning to ask the right questions over mobile phones is universal. The low-income customer of today is the low middle-income customer of tomorrow. Hundreds of millions of people in the developing world are poised to improve their well-being, but this depends on how well we, as a society, listen to them and adjust our efforts to meet their needs.

So much of this rests on the simple act of caring enough to ask the right questions.

The Power of Lean Data

In the last few months, I’ve been writing more about the evolution in how we’re thinking about impact measurement at Acumen. We call in Lean Data.

Until now, there’s really not been a good way for social enterprises to measure their impact in a way that makes sense for them and adds values for their companies and for their customers.

I think we can change that.

For the full soup-to-nuts story of Lean Data, check out the article that we published yesterday in Stanford Social Innovation Review: The Power of Lean Data. I had the great pleasure of writing this piece with Tom Adams of Acumen and Alnoor Ebrahim of Harvard Business School.
