Founder, Upgrading Humans

About

I am the CTO and Co-founder of Pinnacle, an AI research lab built to achieve peak human performance. Our foundational technology is the first AI agent that measures and optimizes your brain’s performance using just your smartphone. I have a deep technical background in translating complex AI into consumer products. I built my first viral iPhone app at 14. I studied Computer Science at Stanford, working in leading AI Researcher, professor Fei-Fei Li’s lab, publishing AI x Healthcare research in Nature and NeurIPS. After graduation, I spent 5 years at Apple Intelligence leading prototyping efforts, filing over 20 patents. Fun fact: I was a national athlete in 3 sports in high school and have been obsessed with the link between measurement and performance since.

Pinnacle goes live tomorrow. Turn your phone into a brain performance coach

Hey everyone! We re the team behind Pinnacle, and tomorrow we are finally launching on Product Hunt.

We started this journey because most 'high performance' tools are just trackers digital chores that tell you what happened to your body, but don't help you understand your mind. We wanted to build a system that helps you maintain focus, resilience, and energy when the stakes are high.

What we've been building: We ve moved beyond simple chatbots to create an AI agent that uses built-in iPhone sensors like HRV (Heart Rate Variability) and voice-based reflection to turn mental signals into actionable clarity. No 'workslop,' just science-backed tools for situational execution.

We would love your support and feedback when we hit the feed tomorrow
