I've written nine non-fiction books and have no idea if I can write a novel. I'm trying anyway: a crypto-thriller called Zero Knowledge, co-written with my AI, Phin Argofy.

I'm good friends with Phil Weiser and Michael Bennet, and I think the world of both. Colorado wins either way. Here's why I think Phil is the right fit for the next four years.

A summer weekend in Aspen - close friends, a gloriously bad movie, running again, and Phin Argofy quietly going autonomous in the work cave.

I read Theo Baker's How to Rule the World in the last 24 hours. It works on a lot of levels at once - memoir, investigation, a study in how power dismisses inconvenient reporting, and a master class in what not to do at the board level.

Meru Health launched Advanced this month - the first integrated mental and physical health program built for founders. Why it matters, and why I invested.

For the month of May, I'm matching donations to the Kabila Founder Mental Health Fund. Plus a free chapter from a new book on founder mental health in tech startups.

On April 29 at 10am PT, Eric Ries and I are doing a free fireside chat for startup communities. We're going to talk about the lessons we've learned as founders, investors, and advisors - and the books we've each just put into the world.

A founder told me seasoned engineers keep saying AI-built software is not possible. I've heard this exact story before - about the Internet, the Web, SaaS, and mobile.
