There are professionals who accumulate years in an industry, and there are those who accumulate depth. Esther Linda Nigiwan belongs firmly in the second category. Over a decade, she has moved through some of the most consequential corners of Africa’s digital financial services landscape, from Numida Technologies’ MSME lending operations in Uganda to Wave Mobile Money’s East Africa distribution machine, from SeerBit’s pan-African payments infrastructure to Pyypl’s blockchain-powered financial inclusion play across Africa and the Middle East.
Now, at the ten-year mark, she has added one more role to her portfolio: newsletter editor at Africa Fintech Insider, her newly launched LinkedIn publication, is her bid to shift more of the continent’s fintech conversation toward the voices of practitioners, the people who have had to make the calls, not just observe them.
We sat down with her to go deeper on the journey, the newsletter, and the state of African fintech in 2025.
When you look back across ten years, was there a single moment when you knew fintech was where you wanted to build your professional life?
It was not a single moment. It was a realisation that crept up on me. Early in my career at Numida, I was working directly with small business owners trying to access credit. These were people running real enterprises, employing people, feeding families, and the traditional financial system had essentially decided they did not exist. When I saw how a simple digital lending product could change a business owner’s trajectory within weeks, something shifted in me. I understood that fintech was not just about technology or transactions. It was about economic dignity. Once you see that, you cannot unsee it. I stopped thinking about fintech as a career and started thinking about it as a calling.
Your path spans distribution, country leadership, and now regional leadership. Did you have a plan, or did it evolve more organically?
Honestly, it was more intention than plan. I did not have a five-year roadmap pinned to a wall. What I had was a clear commitment to always being in rooms where consequential decisions were being made, and to making sure I understood every layer of how a fintech business actually works, not just the layer I happened to be sitting in. I deliberately moved between distribution, sales, and commercial leadership because I wanted to understand the full value chain. The leaders who struggle most are those who have only ever seen the business from one vantage point. Every move I made was guided by one question: what will this role force me to learn that I do not yet know?
Wave Mobile Money and SeerBit represent very different parts of the fintech value chain. What did each teach you that the other could not?
Wave taught me the unglamorous, essential truth about financial services: the last mile is everything. You can have the most elegant product in the world, but if your agent on the ground in a rural trading centre does not have float, does not trust the system, and cannot explain it to a customer, none of it matters. SeerBit, on the other hand, taught me how financial infrastructure gets built and sold at an institutional level, how you walk into a bank boardroom, speak their language, and make the case for a partnership that transforms their digital proposition.
Wendi, which we launched with Post Bank Uganda and which onboarded over two million customers in three months, would not have been possible without the lessons from both. You need to understand the rails and the road.

Which environment energises you more, early-stage startups or established platforms?
I have genuine love for both, but if I am honest, I am most energised at the inflection point, when a company has proven its model but is still hungry, still moving fast, still willing to make bold bets. That is the stage where leadership has the most leverage.
At Pyypl, I joined at a moment when the vision for Africa was clear but the execution was still being built. Being able to architect that, to decide which markets to enter first, which partnerships to anchor, how to structure a team across eight jurisdictions, that is the kind of challenge that makes you better. Pure startup chaos can be exciting but it can also be inefficient. Established bureaucracy can be stable but it can kill momentum. The sweet spot, for me, is building with urgency inside a structure that can actually scale.
What is the most significant shift you have witnessed in how Africa’s fintech sector operates over the decade?
The shift from aspiration to accountability. When I started, the conversation was almost entirely about potential, the unbanked population, smartphone penetration rates, the opportunity. And the opportunity was real. But what has changed is that investors, regulators, and customers are now demanding proof. Unit economics matter. Compliance is not optional. Sustainable growth has replaced growth-at-all-costs.
The companies that are thriving today are the ones that figured out how to serve customers profitably in regulated environments, not just how to acquire them cheaply. That shift has raised the bar for everyone, including me, and I think it has made the sector more credible and more durable.
What has been the hardest professional challenge you have faced, and what did it force you to learn?
Leading a multi-country expansion during a period of global economic instability and tightening fintech regulation simultaneously. At Pyypl, I was building the Africa business across eight markets while navigating central bank requirements that were evolving in real time, currency volatility that affected settlement economics, and a global funding environment that was becoming more cautious.
The easy answer would have been to slow down. The right answer was to get sharper, to tighten our corridor sequencing, prioritise markets where the regulatory path was clearest, and build partnerships that gave us local credibility with authorities. It forced me to become a much more precise thinker about risk, sequencing, and resource allocation. It also taught me that in this environment, clarity of communication with your team is a competitive advantage. When people understand why decisions are being made, they execute better.
How have you navigated the wave of regulatory scrutiny the sector has faced in recent years?
I have always believed that regulation, handled well, is a fintech company’s friend, not its enemy. The companies that approach regulators as adversaries consistently lose. The ones that engage early, share data honestly, and help central banks understand new models tend to get the licences, the approvals, and the operating room they need.
At Pyypl, I invested significant time in direct regulatory engagement across jurisdictions, not just compliance filings. Building genuine relationships with financial authorities changed how we operated in those markets.
As for where it is heading, I expect we will see more harmonisation of cross-border payment regulation across the continent, driven partly by the AfCFTA momentum. That will create real opportunities for platforms that have already built compliant infrastructure across multiple markets.
How has the tightening funding environment changed the decisions being made at leadership level?
It has forced a level of commercial discipline that the sector needed. The years of cheap capital created habits like aggressive customer acquisition with little regard for retention economics, geographic expansion ahead of product-market fit, headcount growth that outpaced revenue.
The funding contraction has been painful for many companies, but it has also clarified what good looks like. Leaders are now making decisions based on path to profitability, not just growth metrics. Partnerships are being structured more carefully.
Market entry sequencing is more rigorous. For someone who has always believed in building sustainably, this environment actually validates the approach. The next phase of African fintech will be built by operators, not just fundraisers.
As a woman building a career in what remains a heavily male-dominated industry, what has your experience actually been?
It is getting better, but not as fast as the rhetoric suggests. The panels are more diverse. The LinkedIn posts about women in fintech are more plentiful. But the boardrooms, the GP tables, the decision-making circles, those are still disproportionately male. My experience has been that the bias is rarely overt. It shows up in smaller ways: being spoken over, having your ideas credited to someone else, being assessed on potential while male peers are assessed on track record. What has helped me is building an undeniable record, the numbers, the markets, the teams, the results, and refusing to make myself smaller to make others comfortable. What is actually driving change is less the diversity programmes and more the visibility of women who are just getting on with it and winning. That is what I want Africa Fintech Insider to contribute to: making more of those stories impossible to ignore.
You launched Africa Fintech Insider at the ten-year mark. Was that timing deliberate?
A little bit of both. The idea had been forming for a while, but there was something about ten years that made it feel like the right moment to stop consuming the conversation and start contributing to it more deliberately.
A decade gives you a particular kind of clarity. You have seen enough cycles to have perspective. You have enough scar tissue to be honest. And you have built enough of a network to know what conversations are actually happening behind closed doors versus what is being said publicly.
I wanted to bridge that gap, to write with the candour and specificity that practitioners have with each other, for an audience that deserves the same level of honesty.
There is already a lot of fintech content about Africa. What gap were you specifically trying to fill?
Most fintech content about Africa is written either from the outside looking in, analysts, investors, observers, or it is promotional, companies talking about themselves. Very little is written by operators, for operators and aspiring operators, with genuine intellectual honesty about what is working and what is not.
The reader I am writing for is the country manager figuring out a regulatory problem in a new market, the commercial director trying to structure a partnership that actually works, the woman in her second fintech role trying to understand how the industry actually functions versus how it presents itself. I want Africa Fintech Insider to be the publication that people in the sector read because it makes them sharper, not just better informed.
What themes do you most want to explore in the newsletter’s first year?
Cross-border payment infrastructure and the real reasons it remains so fragmented. The economics of financial inclusion, whether the business models actually work at scale. Regulatory strategy as a competitive advantage. Women in African fintech beyond the tokenistic narrative.
And the honest post-mortems on companies that did not make it, because we learn more from failure than we are currently willing to admit publicly. And a great deal about leadership and how to climb the corporate ladder in this industry.
Newsletters live and die on consistency. How do you plan to sustain it alongside a demanding full-time role?
By treating editorial discipline the same way I treat commercial discipline, with structure and accountability. I write in the early mornings before the day consumes me. I have a rolling editorial calendar so I am never starting from zero.
And I draw on my daily work for material, the questions I am grappling with in my role are often the questions the sector is grappling with. The newsletter makes me a sharper thinker, which makes me a better operator. They feed each other rather than competing.
If Africa Fintech Insider becomes everything you want it to be in five years, what does that look like?
It is the publication of record for African fintech practitioners. It has broken stories that mattered. It has elevated voices, particularly women, who were doing consequential work without adequate visibility. It has influenced regulatory conversations and investment theses.
And it has built a community of readers who know each other, work with each other, and hold the sector to a higher standard because of the conversations it started. That is what I am building toward.
What is the most exciting development in African fintech right now that is not getting enough attention?
The quiet but consequential build-out of stablecoin infrastructure for cross-border commerce. Beyond the crypto speculation narrative, there are real use cases emerging, merchants settling across borders in dollar-pegged instruments, diaspora remittances moving at near-zero cost, SMEs hedging currency risk for the first time.
This is not yet mainstream, but the rails are being laid. The companies paying attention to this now will have a significant structural advantage within three to five years.
Cross-border payments remain one of the continent’s biggest structural challenges. Where do you see this going?
The infrastructure will improve materially within the next five years, driven by a combination of regulatory harmonisation, the expansion of real-time payment system interoperability, and the maturation of stablecoin settlement. But the harder problem is not technical. It is commercial, building sustainable pricing models that work for all parties in the value chain simultaneously. That takes longer to solve because it requires trust between competitors, regulators, and market makers who do not always have aligned incentives. I am optimistic, but I am a realistic optimist. The corridor I am most excited about is intra-Africa trade payments, which are still absurdly expensive and slow given the distances involved.
Are we actually making progress on financial inclusion, or are we still largely talking to ourselves?
Both, depending on the metric. Account ownership numbers have improved significantly, and mobile money has been genuinely transformative in East Africa. But account ownership is not the same as active financial participation. The person with an M-Pesa wallet who only uses it for airtime top-ups has been counted as financially included, but they are not accessing credit, savings, or insurance in any meaningful way.
The next chapter of financial inclusion is about depth, not breadth, moving people from access to active participation. That requires products that are actually designed for the way people at the base of the pyramid manage money, which is much more complex and irregular than most product teams assume.
What is your honest assessment of where Uganda sits within Africa’s broader fintech ecosystem?
Uganda is underrated and under-invested relative to its actual capabilities. We have genuine mobile money penetration, a young and digitally native population, a regulatory environment that has become more progressive, and an entrepreneurial culture that produces resilient operators. What we lack is the capital density and ecosystem infrastructure of Lagos or Nairobi, the accelerators, the angel networks, the institutional funding pipelines. But I think that gap is closing. The talent is here. The market is real. What Uganda needs is more of its own success stories told loudly enough that global capital starts paying closer attention. That is partly what I am trying to do.
What does a ten-year career in fintech do to you, personally? What does it cost, and what does it give back?
It gives you a particular kind of resilience, the kind that only comes from having been in markets that collapsed, partnerships that fell apart, and products that launched to silence instead of applause. It also gives you pattern recognition that is genuinely valuable and hard to teach. What it costs is harder to name.
There is a relentlessness to operating in high-growth environments that does not easily switch off. But what it gives back, the knowledge that the work matters, that the markets you entered are more financially connected than they were before you arrived, that is a reward I would take every time.
Who are the people who shaped how you think about this industry?
I am deliberately careful about naming individuals because the truth is it was rarely the loudest voices in the room. It was the operators, the country managers, the compliance leads, the product people who sat across from me and were honest about what was not working. The colleagues who pushed back on my assumptions and made me defend my reasoning.
The customers who told us, in their own words, why our product did not work for them. Those are the teachers I am most grateful for. The industry talks a lot about mentorship from above. I have learned just as much from peers and from the people we were trying to serve. That said, I would not be honest if I did not acknowledge Adams Kibet, who lit a particular light in me during our time together at Wave.
If you could speak to yourself on the first day of your fintech career, what would you tell her?
The sector will change faster than you expect and slower than it promises. Stay close to the customer and stay rigorous about the numbers. Those two things will never mislead you. Do not wait to be invited into rooms; build the credibility that makes you impossible to exclude. And invest in other women earlier and more deliberately than feels comfortable, because the ecosystem you wish existed will not build itself.
What do you want people to say about your contribution to African fintech in another ten years?
That she built things that lasted. That she opened doors she did not have to open. That she told the truth about this industry at a time when it was easier not to. And that Nigiwan was a force to reckon with.
