I build products people love, and help founders do the same.

Build

Users don’t care how hard something was to build, only whether it works the first time. I like messy problems, where the path isn’t obvious and product, tech and business have to be solved together.

Looking for my next role, and always happy to talk about what you’re building.

Invest

The best founders watch what users do, not what they ask for. If you’re deep in a real problem and moving fast, I’d be glad to help where I can. Here’s where I’m looking right now.

• Fintech

  If you’re making money simpler, fairer or more global, especially for people the old system overlooks, let’s talk.

• Healthtech

  Healthcare still runs on paperwork and waiting rooms, and I’m interested in anyone changing that.

• Edtech

  AtlaSlope started as my own study tool, so I care about learning that sticks and doesn’t waste your time.

  I backed Eevi, an AI tutor that gets you speaking a new language from day one.

Advise

Strong convictions, weakly held. Being wrong early is cheap. Being right late is expensive. Most of my work is helping teams find out fast whether an idea is right, with the smallest test that will tell them. I work with a few teams at a time, so each gets real attention.

• Product strategy

  Deciding what to build next, and what to stop building.

• The product team

  Hiring your first product people, and building a team that doesn’t need you in every meeting.

• Zero to one

  Getting from an idea to something people actually use.

• Regulated products

  Licences and compliance planned in from the start, so they don’t slow you down later.

Projects

Side projects are where I try things out, mostly for fun. Right now they’re about wine: one maps where it comes from, the other helps you choose what’s in your glass.
