I love to solve hard technology problems that make people's lives better. That led me to build Forethought at the start of the AI wave — agentic AI powering over a billion customer interactions a month, acquired by Zendesk — and now Espa Labs, the AI executive assistant that helps everyone achieve more. I'm also going deep on quantum computing — which will be the next technological wave.

Startups

What happens when a hard problem meets a market. Founder & Chairman of Forethought (agentic AI powering 1B+ customer interactions a month, acquired by Zendesk) and founder & CEO of Espa Labs (the AI-native executive assistant, featured in Fast Company and on CNBC). I write about the journey in Sum of My Mistakes.

Investing

Backing the next generation. Angel investor in 30+ companies including Anthropic, Cognition, Neon, and Bluesky; LP, board member, and mentor to founders — paying forward the access I was given.

Algorithms

How I learned to solve hard problems. Theory of Problem Solving: 100+ competitive programming problems with full deconstructed editorials — the intuition, false starts, and proofs, not just the answers.

Quantum

The next technological wave, understood from first principles. Quantum algorithms dissected and reconstructed — plus Understanding the Universe, my narrative journey through physics.

Research

Curiosity, formalized. Publications in mathematical physics and machine learning, and patents in AI systems.

My core focus is building Espa Labs — if you want to build with us, I'd especially love to hear from you. Also the right place for investing and media inquiries.
