About
I partner with companies building in AI and web3.
10+ years in product across AI and web3. Leading teams from unicorns to early-stage startups. I still build things myself, using an AI-first approach on everything I do.
I started as an engineer, on a team Pinterest acquired. In 2015 I founded an AI startup in customer service, years before OpenAI and Anthropic. Since then I've led product at Pass, Enso, Klarna, Preply, Letgo and many more.
How I work
Thorough by default
I focus on details others skip. The work should be from end to end, that's what builds trust.
Design and code, not just specs
I take ideas from ideation to production. Prototyping makes product decisions sharper.
Outcomes over output
I optimize for shipped impact and metrics that move, measuring what works and what not.
