Paul W.
San Francisco, California

38 jobs
I've started 3 companies as both CEO and CTO, raised over $15m, delivered 50+ AI consulting projects, and studied AI at Stanford.
I'm currently only available for a few hours every now and then, usually helping founders and executives navigate things like AI, company building, fundraising, hiring, and cofounder breakups.
People call me when:
(1) they're thinking through a major decision and want to talk to someone who can help them achieve clarity
(2) they're exploring something new and want to talk to someone experienced who can help them make sense of it all
(3) they're experiencing the depths of the startup rollercoaster and want to talk to someone who's been there to gain some perspective
I've advised 15+ pre-seed to Series A clients that have collectively raised tens of millions of dollars. Some testimonials from previous clients, some of whom I've been working with for years:
"Paul was a bright light at a very dark time at the beginning of our business. When there were initially doubts about the direction to move in, Paul instinctively broke down the issues one-by-one and provided a completely different perspective, ultimately renewing our hope and confidence in our decisions. His comprehensive business knowledge, coupled with his exhaustive experience in almost every topic made him absolutely invaluable as a mentor to our team. I cannot thank him enough and wholeheartedly recommend him to anyone looking for grounded, objective startup business advice. Thanks, Paul!"
- CEO of a bootstrapped AI startup that successfully reached PMF
"Paul is a superb asset to our team and has been for over a year. His thorough knowledge of real-world AI/ML techniques, combined with his ability to thoughtfully and supportively respond to our questions has helped our program to quickly level up. To our surprise, weโve also found Paul to be a great source of insight for all things startup-related, from roadmaps to fundraising to mindset. If youโre thinking of hiring him, Iโd imagine you will quickly discover the same."
- CEO of AI startup I've helped grow from 0 to $1m+ revenue (and an acquisition offer)
