Hello!

I've been building start-ups since 2012. Half in the UK and half in San Francisco. I use this blog to share the lessons I've learned along the way about early-stage product market fit and growth.

I am currently the CEO and Co-Founder of Pump Up, a new type of multi-player harness which allows teams to collaborate with agents to run entire business processes.

I started my first real company as part of the very first Entrepreneur First cohort and Y Combinator's S2013 batch. Since then I've built a few things:

My background is technical. I started coding when I was about 12 or 13. My first introduction to programming was writing exploits and keygens in the mid-2000s with a combination of C, Perl, and x86 asm, learned primarily through hanging out on IRC and reading Phrack.

More recently I have been focused on speaking to customers, sales, and fundraising; but I still write a fair amount of code on the frontend.
