I build the things I want to use, and sweat the details until they feel simple.

About

I build better than I trade. It took a law degree, a startup, and a full-time trading stint to work that out.

I grew up in South Africa. Studied politics, psychology, and philosophy, then law, then spent two years as an M&A attorney at Hogan Lovells. I left to co-found Hubtiger, a cycling-analytics startup. After exiting I traded crypto full-time, long enough to realise my passion for building. I joined Nansen in 2021, went from Growth to Staff PM, ran the core analytics product, and now lead trading: turning a platform people use for analytics into one they trade on.

Away from the screen I'm a father, happiest on a long mountain walk with my golden retriever or a mountain bike ride. Most of my non-work screen time goes to managing my portfolio or researching health hacks.

How I think about product

  1. Become the user.

    Don't study users from a distance, become one. I trained for multi-day stage races to build for cyclists, and moved my whole portfolio into crypto. Their problems become yours.

  2. Users owe you nothing.

    You're one of a hundred products they touch. Nobody reads the docs or files the bug report, they just leave. Build like every session is a trial about to expire.

  3. Run the roadmap like a portfolio.

    Trading taught me position sizing. Size bets by conviction, cut losers fast without ego, add to the winners. Most roadmaps do the opposite: equal bets, kept alive too long, starved the moment they start working.

  4. Embrace AI, reject slop.

    I build from the terminal with AI all day, agents running in parallel. That's not the edge; soon everyone works this way. The edge is knowing what good looks like before the model does. Use AI for leverage, never for judgment.

  5. Be opinionated.

    If it needs configuring before it's useful, you skipped the hard decision. Ship the default you'd pick yourself, and let the few who care override it.

  6. Marketing is part of the product.

    Half the product failures I've seen were narrative failures. The team built the thing and assumed it would explain itself. If you can't frame why it matters, you've built half a product.

  7. Question feedback deeply.

    The most dangerous feedback is articulate feedback from the wrong user. Confident, specific, well-meant, and it quietly steers you away from the people you're actually building for.

What pulls me in

Markets

The largest and most honest information system humans have ever built.

A rare arena where amateurs and professionals compete on the same field, in real time. Trying to hold your own against the best is exceptionally stimulating.

Crypto

A free, more inclusive financial system, where anyone can own the same assets without third-party risk.

I came in with the 2016 cohort, for what Bitcoin and Ethereum were really about, and a decade in I still believe it. Access to the same assets, anywhere, with no one standing in the middle.

AI

The greatest enabler of my lifetime.

I can take an idea to a working version in a day, across product, design, and code. One person can build more than ever now.

Longevity

Optimising the one asset that compounds longest: my own health.

Diagnosed with cluster headaches in 2020. There's barely any research, and doctors said they can't be prevented. I've been extending the gap between cycles by about a quarter each year, and I won't stop until I've beaten it.
