About Me
I'm an inventor who loves creating new products, including Pebble (the first smartwatch) and Beeper (a universal chat app). I also spent 4 years as a partner at Y Combinator. I enjoy advising early stage startups - especially hardware!
I don't reply to suspected AI-generated email (sorry).
