HOW PLENTIFY IS TURNING AFRICA'S ENERGY CRISIS INTO A GLOBAL CLIMATE SOLUTION
1. You spent a significant part of your career in globally recognized firms such as Google, McKinsey, South Pole. You worked as an advisor on renewable finance to the South African government. What led you to leave this prestigious career to start a hardware company building geyser controllers?
Through all those roles, I saw that most clean energy activity in Africa at the time fell into two buckets: large wind and solar projects to power the grid, and tiny home systems or micro grids to provide electricity access.
Very little was being done for the majority of Africa's population that was already connected to a grid system but suffering the world's most expensive and unreliable power.
When this problem and opportunity dawned on me, I was at Google, and this was not within their strategic focus. If it was something I was going to tackle, I would have to go it alone.
By then I was not unfamiliar with building. At Google, I helped build out a transcontinental African energy team across Kenya and California, I built the Sub-Saharan African office of South Pole Group into a sustainable operation, and I even created a small consulting business that helped to fund grad school for myself and my partner.
So armed with a healthy dose of delusional optimism, I quit my job at Google and dove head first into Plentify.
2. Plentify’s core idea is simple but counterintuitive: shift when homes use energy, not how much. How did you convince your first customers, partners, and investors that this was the right problem to solve, given how entrenched traditional energy thinking is?
The first people we got to believe in our mission were our people. We managed to attract a truly incredible group of engineers, designers and operators very early in our business that really believe in our mission and epitomize our values. They have laid the foundation for much of our success.
Convincing investors took time. We had our first successes with visionary grant providers who provided catalytic capital either because they backed our vision or backed us as social entrepreneurs taking risks to make an impact in the world. So much credit is due to Echoing Green, the Tamer Fund for Social Ventures, the African Entrepreneurship Awards, GIZ, EEP Africa and Digital Energy Africa.
After we showed some progress, we were able to secure the support of commercial investors. This started with a family office who knew us well, and later grew to include top climate venture investors from Africa and North America.
Convincing customers was a journey. In our early days, we tested the desire for load management in multi-dwelling buildings as a way to drive down electricity costs. It was so hard to grab attention – customers had no idea what load management was, and electricity spend was just not material enough for them to care.
We maintained conviction that this was the future and continued building towards it, even while we served other applications with our technology, for example in detecting water heater leaks in partnership with insurance companies.
Fast forward a few years though, and South Africa’s load shedding had completely transformed the market. Now not only did customers know what load management was, but they saw it as key to solving the acute energy problems that they were facing, and were actively seeking out our services. Now even Balwin, the largest residential property developer in South Africa, has made our technology a standard feature in their developments.
3. South Africa’s load-shedding crisis was brutal, but your co-founder has said it “forced Plentify to solve real problems immediately.” How did this adversity shape the company, and in what ways did it give you a strategic edge over competitors?
We have grown up through a very interesting time in South Africa: We have faced an acute energy crisis with outages of up to 10 to 12 hours per day. At the same time (and as a result) we have experienced one of the world's most rapid energy transitions, where the share of private generation grew from 3% to 18% within the space of 3 years.
In the face of this rapid disruption and change, we have needed to build solutions to address so many different energy problems. This has positioned us very strongly, as our product is now much more multifaceted, powerful and resilient than competitors that have grown up in much more stable markets without the diversity of problems that we have had the advantage of solving.
4. Plentify manages hardware, software, and AI simultaneously - notoriously complex to scale. Where has that complexity caught you off guard, and how have you had to rethink processes or the business model as you’ve grown?
This has been very complex to scale, and there are a few examples of how we have been caught off guard:
As a first example: early on, we took the approach of building things that don't scale – ensuring that we had a market for our products before we over-invested in processes. That was a very useful and advantageous approach to remain nimble and allow us to find our niches in the market.
However, when we started scaling rapidly, this put a lot of pressure on the people on whom these hacky systems were relying.
We have since invested heavily in our internal systems function and the technology to support and automate our operations, so that we can scale programmatically. I don't think I would have done anything differently here, as remaining nimble was necessary to get to where we are.
As a second example: When we were going through a particularly rapid growth cycle, we faced a hairy moment where the working capital requirements to fund the hardware to satisfy this demand were putting our balance sheet at risk.
When that happened, we managed to change our business model to receive more cash up front and secure debt financing for working capital. In this case, I wish we would have anticipated these cash requirements sooner.
5. The intelligence behind your consumer devices sits in the Plentify platform ; the AI that learns behavior patterns, weather data, and load-shedding schedules. How advanced is that system today, and what are the biggest challenges still left for it to solve?
We've been building the system for the better part of a decade, so it's pretty advanced by now. The Plentify platform orchestrates the home’s energy demand in real-time. It solves the mismatch between electricity demand and the cheapest, cleanest energy extremely effectively, and does so in an individual home, in a microgrid like an apartment building, or across the distribution network.
This is not a static problem though. The electricity system is going through a multi-trillion dollar transformation. In every step of this transformation, the challenges imposed on the grid, the regulations that are in place, and the incentives that exist will evolve. We need to constantly be innovating for this new energy future.
6. You sell both consumer devices and B2B energy solutions to developers and utilities. How do you balance these very different customer segments, and which segment is currently driving your growth most effectively?
We are primarily a B2B2C business where property companies and solar companies are our biggest channels. They adopt our technology because it helps their energy systems shift more of their consumption to cheap solar, arbitrage grid electricity tariffs, and reduce the size of battery storage required.
We also sell direct-to-consumer through our website, but that is a small portion of our business and is there primarily for us to test and learn about the end user as much as possible. This enables us to package those lessons and give it to our B2B partners so that they can be as effective as possible at selling.
7. You’ve raised nearly $15 million from investors across South Africa, Europe, and North America. As an African founder scaling energy infrastructure, what do international investors still misunderstand about building solutions here, and how have you navigated that?
We only have experience with investors that are interested in energy and hardware in general. Within that pool, we have found that international investors who are not interested in investing usually point to Africa being unfamiliar to them in terms of operations, legal frameworks, and general risk.
For those who we have managed to attract, it is due to a combination of their appreciation for the immense opportunity in Africa, and for the applicability of the technology that we are building for energy systems around the world.
8. Plentify is preparing pilots in the UK, Australia, and Brazil. You built your playbook in one of the world’s most extreme energy environments. What has translated well to these markets, and what has surprised you about exporting your model?
Our foray into these markets has validated that the energy problems that we are solving in South Africa are global. They take slightly different shapes in each market in terms of the regulations that exist, the loads that are most important, and the channels that dominate – but ultimately it's the same underlying problems that need to be solved.
9. You are an Archbishop Tutu Leadership Fellow and Echoing Green Fellow, linking leadership to social purpose. As Plentify scales commercially, how do you ensure these values remain central to your culture and decision-making?
Plentify is first and foremost a mission-driven organization. We exist to fulfill our mission of enabling utilities to deliver affordable, reliable, and clean energy. Our business model is fully aligned with our mission, meaning that the more we sell, the greater impact we have.
In addition, we have defined a set of values, and we hold each other accountable to behave by those values. Our first value is Impact, centralizing the importance of the mission to who we are, and how we engage and make decisions.
10. Africa produces very little carbon yet faces severe climate consequences. What do you want people globally to understand about the work African climate-tech founders like Plentify are doing, and why it matters far beyond the continent?
Our experience at Plentify has been that South Africa has been the most incredible laboratory for building our business because of the plethora of energy challenges which exist.
As African climate-tech founders, this is not unique, and there are many areas where Africa will experience the impacts of climate change long before anyone else. By solving these local problems, but doing so in a scalable way which has a global market in mind, we can create more opportunities to export African-born technology to the world.
