Startup Lessons from Three Ventures, Y Combinator, and 100+ Coaching Clients

I've spent over a decade in the startup world — as a Y Combinator founder (Ridejoy, W12), a product builder (Headlight, Midgame), and a startup coach working with 100+ founders navigating everything from first fundraise to acquisition. These posts capture the hard-won lessons from that journey.

Whether you're raising your first round, pivoting for the third time, or wondering if you still have the fire, this page collects my best thinking on the craft of building companies and the mindset required to survive the journey.
