Work

Fifteen years crafting software for everyone from the Fortune 500 to folks on the subway. I still get a kick out of spotting my work in the wild.

• 2026Microsoft Excel: Design Director, leading product and design for the AI agents shipping to a billion+ people and their spreadsheets
• 2017Microsoft Outlook: led design for mobile on iOS and Android, took it from 100M to 300M+ weekly active users around the world. Read the case study
• 2015RogerTalk: founding member of a venture-backed zero-to-one, $1M raised from Chamath Palihapitiya, grew to 100K+ users

• 2011The Cools: a fashion marketplace with 50K users, LVMH's Antoine Arnault advising and the fashion press watching

Writing

Essays on building AI products, shipping at scale, and why software feels the way it does.

• What I've learned shipping AI agents in Excel
• What I look for in AI-first founders
• Outlook mobile: from 100M to 300M weekly users
• Thoughts on building a successful remote team
• How a side project started a conversation about our dear NY subway system
• Spotify: what we learned about sprints

Investments & advisory

I started angel investing in 2025. Two cheques so far, both into AI-first products, at $25k+ pre-seed and seed, and I bring other angels in. Then I stick around: product and design reviews, your first product or design hire, and a zero-to-one product leader who has shipped at billion scale.

I'm backing the founder more than the product. The five things I check, in order, are in What I look for in AI-first founders.

• Invested Biscuit build and run a business from a prompt
• Invested Pretty Data AI revenue tools for SMB
• Advised Institute for Advanced Architecture as technical specialist
• Send me your demo

Things I make

Side projects that scratch an itch. Small, shipped, and occasionally useful.

• BlixtSnap a Mac app for screenshots
• Essential Mix a SoundCloud mixtape for makers looking to flow
• NYC subway app an iOS app for the MTA, featured in The New York Times

Talks & interviews

I talk about what it takes to ship AI to a billion+ people, and what early-stage teams can steal from it. I'm saying yes to more conferences, podcasts, and press. Get in touch.

• 2025Speaker at the AI Summit, Barcelona
• 2023Interview with Lovers Magazine

Contact

Founders first, but product and design questions are always welcome. Barcelona-based, happy to talk across time zones.
