Builder, investor, immigrant. A life across four continents, three companies, and 75+ investments — told as a timeline.
Born at a hospital in Johannesburg to parents already living in Klerksdorp — a small mining town in what was then the western Transvaal. Gold country. The landscape — flat, vast, heat-hazed — would become a metaphor for everything that followed.
Neil Armstrong walks on the moon. The world watches on television sets that most South African households do not yet own.
Growing up in a home where debate was the dinner table sport. Ideas were tested, not accepted. The habit of questioning everything — including the world outside the window — started here.
Students in Soweto march against Bantu Education. Police open fire. The image of Hector Pieterson becomes the icon of a generation's refusal. For a child growing up white in a mining town, the distance between Klerksdorp and Soweto was geographic, not moral.
Studies Business Science at UCT. Elected to the Student Representative Council. The campus is a crucible — anti-apartheid politics, intellectual ambition, and the question of what a young South African owes the country he was born into.
Conviction before consensus. As a white South African in the late 1980s, the comfortable path was to look away. He helped organise demonstrations against the apartheid government's practice of detention without trial, and was detained at one of them. The clearest memory from that day: the hatred in the eyes of the policemen, and the German Shepherds — trained to terrorise — lunging at the crowd. The willingness to put short-term comfort aside for a battle worth fighting crystallised here. It never left.
The wall falls. The Cold War ends. In South Africa, the dominoes begin to move.
Nelson Mandela walks out of Victor Verster Prison after 27 years. For South Africans who had marched and been detained, this is the moment the world tilts.
South Africa was on the cusp of real change, but Cape Town — pre-internet — felt disconnected from the rest of the world. The pull was outward: to connect, to test himself against the best. He still loves the smell of the bush — the salty Atlantic pounding the rocks at Bantry Bay, the vast Kalahari silence, the light of the Cape. South Africa remains one of his homes. But the world was bigger than one country, and he needed to find out how much of it he could reach.
Israel: a country that builds with urgency — small, surrounded, perpetually reinventing itself. For a South African who had just watched one country transform, Israel felt like another place where nothing was settled and everything was being built. Israel becomes, alongside South Africa and Britain, one of the three countries that define him.
Serves in the Israeli Defence Forces. A South African immigrant in his early twenties, in a country not yet at peace. Real combat teaches you things nothing else can — how to function under genuine pressure, how to trust the people beside you, how to make decisions when the stakes are not theoretical. The resilience and clarity that came from military service never left.
Completes an MS in Management through the joint Boston University / Ben-Gurion University programme, physically based in Israel. Simultaneously begins working in investment banking.
Three years at YLR Investment Management, focused on financing the emerging Israeli technology sector. This is where the instinct for building starts to replace the instinct for studying — seeing founders up close, understanding what makes technology companies work from the inside.
Joins a start-up to help build Barzelan, a high-tech steel wire manufacturing company in Beit Shemesh, Israel. Factories, physical logistics, raw materials, supply chains, inventory, and sales. Before fintech, before software — the first venture was built with metal.
Supply Chain Connect and its founder moved to London — to be close to customers, to build the centre of the business somewhere he could understand the market deeply. London had always been a great global city, and when the opportunity came to build there, he jumped at it. Fourth country. Another continent, another chapter.
The bubble bursts. Billions evaporate. For a software company just getting started, survival meant something specific: keeping the business funded when the European VC ecosystem virtually shut down, holding the team together, finding customers willing to pay real money for real software while the dot-com wreckage was still smouldering. The lesson carried forward: real businesses outlast stories about businesses.
Founds Supply Chain Connect, a hosted, cloud-based supply chain software company and B2B marketplace for industrial procurement. The idea: bring transparency, efficiency, and automation to a world still running on fax machines and phone calls. Built from London during the dot-com bust.
The towers fall. The world divides into before and after.
Supply Chain Connect is acquired by ChemConnect. First company built, first company sold. The cycle of building something from nothing and letting it go begins.
Founds Wonga — born from a conviction that the traditional finance industry was built on outdated assumptions, prejudicing many people. Credit decisioning was still dominated by bank managers who tended to be white and middle-aged, implicitly prejudicing those who weren't. Damelin believed that by 2005 there was enough data and alternative information available that machines could make less prejudiced, more consistent, and more appropriate decisions than humans for many purposes. The insight was the basis for what became the world's first real-time AI system in consumer credit — already in place from the moment Wonga went live in 2007.
The global financial system seizes. Banks that were too big to fail do exactly that. Wonga, born in the middle of the crisis, grows profitably as trust in traditional finance collapses — funded, profitable, and expanding while almost every finance business worldwide was on the brink of collapse.
Satoshi Nakamoto mines the first Bitcoin block. A new financial system begins to emerge in the margins.
Scale. The automated lending model proves out. What started as an experiment becomes infrastructure.
Named TechCrunch Founder of the Year (2010), Guardian Digital Entrepreneur of the Year, and Ernst & Young UK Entrepreneur of the Year (2011).
Introduced to Bitcoin by Wences Casares — the Argentine entrepreneur who would become known as 'Patient Zero' for bringing crypto to Silicon Valley. The main point of Bitcoin wasn't its price as an asset. It was freedom from human decision-making — the same theme that had pushed him to create Wonga. The network is global, inclusive, and available to anybody anywhere. To this day, he considers it one of the greatest human inventions.
Wonga grew from launch to over $500 million in annual revenue in five years — a run-rate above $500M when Damelin resigned as CEO in November 2013. The company was generating over $100M in annual cash flow, with a customer Net Promoter Score of 73 — in Apple and Google territory, ahead of every bank in the UK. Internally, the business was strong. Externally, two forces made it impossible to build the broader financial technology platform he envisioned: a board split between those who wanted to invest in new markets and those focused on near-term financials and an IPO; and regulatory friction from authorities who didn't yet understand the product, its AI-driven decisioning, or its customers. A large secondary share sale resolved the impasse, and Damelin moved on. The lesson stayed: a great product and great customers aren't enough. Without a unified board and a clear strategic mandate, even the strongest business can be pulled apart from within.

A pattern that would define the next decade: build something meaningful, push it as far as it will go, then step back. Decompress. Open the mind to what comes next. Make good decisions, not fast ones. During this period of reflection, two things emerged. The first was the concept for Tide — which would become another billion-dollar business. The second was the realisation that investing, backing other builders at the earliest stage, was not a side project. It was the next chapter.
Formalises the investing practice under the Rhythm Ventures banner. The precursor to Dust Road Ventures — same instinct, same approach, earlier chapter.
Begins writing seed-stage cheques full-time. The operator becomes an investor — but the instinct is the same: find people building things the market doesn't yet know it needs, and back them before the road is paved.
Co-founds Tide, a digital banking platform for small businesses. The third company. Conceived during the interregnum, built into another billion-dollar business. Proof that the builder's instinct doesn't retire — it finds new problems.
The UK votes to leave the European Union. The tectonic plates of European politics shift.
The world stops. Companies built for digital thrive. Companies that weren't, don't.
Wise lists on the London Stock Exchange. Cazoo lists on the NYSE. Two portfolio companies reach the public markets.
The worst attack on Jewish civilians since the Holocaust. For someone with deep roots in Israel — one of the three countries that define him — this is not a news event. It is personal.
Fifteen years after the genesis block, Bitcoin crosses $100,000. Twelve years after Wences Casares first introduced the idea, the thesis has played out.
The investing practice is formalised as Dust Road Ventures — a seed-stage investment firm deploying permanent private capital. The name comes from the roads of southern Africa: unpaved, uncertain, and the only way to get somewhere no one has been.
A new venture is taking shape — solving a pain point that most people don't know exists yet. AI has opened paths that weren't previously possible, and the feeling is one Damelin recognises: the same charge he felt in 1994 when he was first introduced to the internet and fell in love with the global connectivity and the opportunities to connect people everywhere. He has never been more excited about building. The portfolio is deepening. The writing is starting. The story isn't over. It's accelerating.
