I’m Brad Feld. I’ve been playing with technology since I got an Apple ][ for my bar mitzvah. I’ve co-founded a handful of companies including Techstars , been a VC investor for 30 years, and have been blogging at feld.com for over 20 years. I’ve also written a bunch books about entrepreneurship .
This site is where I write about building with AI - specifically Claude Code, the tool I use every day to build software. I’m the co-founder and very part-time CTO of IntensityMagic , where we’re building a multi-product SaaS platform with a two-person team and a lot of AI.
Topics you’ll find here:
- Claude Code - workflows, skills, commands, and daily development
- CompanyOS - running a company with AI agents
- Open Source - contributions and projects
- AI Coding - what works, what doesn’t, and what I’m learning
The source for this site is on GitHub . It’s built with Hugo and PaperMod, deployed on Vercel, and the entire content pipeline - from note capture to publishing - runs through Claude Code.
