By 2012, four years after market launch, Wonga had grown from a single-floor startup to a company producing roughly £309 million in annual revenue and £62 million in net profit. Customer Net Promoter Score sat at +73 — a number we cited publicly and that, at the time, exceeded every UK retail bank by a wide margin. The credit-decisioning engine had become one of the first fully-automated real-time systems in consumer credit anywhere in the world, and a generation of customers who had been quietly excluded by traditional banks was responding accordingly.

By every external measure, the business was a triumph.

In November 2013, I resigned as CEO.

The story of why is the most important thing I took out of those seven years, and it is not the story most people tell about Wonga. It is a story about conviction — about the difference between conviction inside a single founder’s head and conviction inside a board.

The fracture

Externally, two forces had converged.

The first was a board split between those who wanted to invest in new markets, new products, and the wider financial-technology platform the engine had been built to support, and those focused on near-term financials and an IPO. The original company was always meant to be one product on a much larger system. The dispute was about whether to fund the system or sell the product.

The second was regulatory friction from authorities who did not yet understand AI-driven credit decisioning, did not yet understand the customers we were lending to, and did not yet understand that the alternatives those customers had been using were structurally worse. Some of that scrutiny was deserved and some was misdirected. Either way, the regulatory weather was changing, and the room was divided about how to respond.

Either of those forces alone would have been a hard problem. Together they were terminal — not because the business could not survive them, but because the strategic mandate to build the broader platform was no longer there. A large secondary share sale resolved the impasse, the share register reshaped itself, and I moved on. Niall Wass took over as chief executive.

What followed was a different company. The strategy narrowed: fewer markets, fewer products, retreat from the internationalisation roadmap, replacement of the custom risk model with off-the-shelf software, reallocation of investment from data science and engineering to regulatory compliance. There was turnover of almost the entire team as a consequence. It did not end well.

The lesson stayed with me, and it has shaped how I write cheques today.

What I had got wrong

A great product and great customers are not enough. The unit economics are not enough. The team is not enough. The market is not enough. Without a unified board and a clear strategic mandate, even the strongest business can be pulled apart from within.

I had built Wonga around a single insight: that by 2005 there was enough data and alternative information available that machines could make less prejudiced, more consistent, and more appropriate credit decisions than humans for many financial purposes. The insight was correct. The product worked. The customers loved it. The numbers proved it.

But conviction inside a founder’s head is private. Conviction at a boardroom table is public, and it has to be reaffirmed every quarter, in conditions neither side foresaw when the cap table was assembled. Capital is not patient on its own. Patient capital is a discipline, and the discipline is shared.

In retrospect, three failure modes had been compounding since the Series C.

The first was a slow drift in the cap-table mandate. Each successive round attracted investors whose internal models for our business looked different from the previous round’s. There was no document at the table for any of those rounds that said this is exactly what we are building, on this timeline, in these geographies, with this technology as the platform. Without it, every new investor brought their own version of what they thought they had bought. Those versions diverged over the next three years. The divergence was invisible until it wasn’t.

The second was the difference between investors who wanted the company I had described and investors who wanted the equity I had offered. Both were honourable positions. They were not the same position. I had not done enough work in the early rounds to test which was which.

The third was the implicit assumption that strategic alignment, once present, would stay present. It does not. Board alignment is not a state. It is a practice. Every quarter you have to rebuild it, in conditions that may not resemble the conditions in which the alignment was first formed.

What I would do differently

Looking back, I would have done a few things differently.

I would have raised less capital, more slowly, from people whose strategic mandate matched mine for longer than three years. I would have spent more time in the early rounds testing not just whether an investor wanted the equity, but whether they wanted the exact business I was building, in the exact geographies I planned to be in, on the exact timeline I needed to get there.

I would have written the strategic mandate down — what we are building, what we are not building, when each milestone matures, what counts as a deviation — and asked every new shareholder to read it and sign before the cheque cleared. Not as a legal instrument. As a brief, shared, written record of the version of the company each new investor was buying into. The point was never enforcement. The point was making the assumptions visible so that drift would be observable.

I would have spent more time, deliberately, putting the founder voice and the board voice into the same room before a crisis arrived. The conviction of a founder and the conviction of a board are not the same instrument. They have to be tuned to each other. That tuning takes hours that feel unproductive at the time and are the most productive hours in the life of the company.

How this changes what I look for now

The hardest part of that lesson is that it cuts both ways. As a builder, you have to be uncompromising about who shares your conviction before they buy a seat at your table. As an investor — which is what I have been since 2014, and permanently since Dust Road Ventures was formalised — you have to be honest about what you are buying when you write the cheque.

You are not buying equity. You are buying a seat at a table where conviction will be tested under pressure. The test will come — usually two or three years in, when the markets shift or the regulators arrive or the early-customer flywheel slows. If you have not earned the founder’s trust before that day, the day will not go well.

When I evaluate a seed-stage company now, the cap-table question I am most interested in is not who else has come in, or at what valuation. It is: does this founder know exactly what each investor on this table believes they have bought? If the answer is no, every subsequent round will compound the same misalignment I lived through. If the answer is yes, the founder has the only piece of infrastructure that protects long-term conviction from short-term pressure.

I still believe Wonga was the right company at the right time. Built profitably through the global financial crisis, when almost every other finance business worldwide was on the brink. Built around a credit-decisioning system that focused on repayment probability rather than on what a person looked like or where they came from. The customers — millions of them — were not a mistake. The technology was a leap. The numbers were real.

What broke was the alignment between the people in the room and the company on the page.

A great product and great customers are not enough. I will spend the rest of my career remembering that.

Questions

Why did Errol Damelin resign as CEO of Wonga in November 2013?
The board had divided between investors who wanted to back the broader financial-technology platform Wonga's engine had been built to support and investors focused on near-term financials and an IPO. Regulatory friction from authorities who did not yet understand AI-driven credit decisioning compounded the split. The strategic mandate that justified the original company was no longer in the room, so he stepped down and moved on. Niall Wass took over as CEO.
What is the difference between founder conviction and board conviction?
Conviction inside a single founder's head is private and durable. Conviction at a boardroom table is public, and it has to be reaffirmed every quarter under conditions neither side foresaw when the cap table was assembled. The skill of running a venture-backed company is not having conviction — it is keeping conviction aligned across people whose mandates and time horizons diverge over time.
What does Errol Damelin look for in board alignment now when he invests?
A documented strategic mandate signed at the cap-table stage — what the company is building, what it is explicitly not building, when each milestone matures, what counts as a deviation. He treats divergence from that mandate as a serious early signal, often more telling than a missed quarter.
Does this lesson contradict the dust-road thesis?
No — it strengthens it. The dust-road thesis is about backing founders who see a path the market does not yet believe in. Founder conviction is the starting condition. Board alignment is what keeps that conviction able to act across the long stretches when the market has not yet arrived.
