About Brad Feld

Brad Feld has deliberately structured his career into "third thirds," treating his current phase as focused on wisdom and mentorship rather than chasing new power, and operates by a "Give First" philosophy where he provides help without expecting returns while treating founders as peers rather than transactions. He pioneered the "startup community" concept and Boulder Thesis that shaped how cities worldwide build entrepreneurial ecosystems, and has been unusually open about founder mental health by sharing his own experiences with depression and anxiety to normalize these discussions in venture circles.

Brad Feld's Interests

What they've been talking about across their social media accounts
  • Deep engagement with hands-on coding and artificial intelligence, specifically documenting a personal journey using tools like Claude to build software. He shares granular technical insights from his own development work, such as using Next.js and Supabase, automating documentation, or rebuilding websites with Hugo, effectively treating AI as a daily pair programmer.
  • A profound appreciation for literature and the publishing world, frequently recommending books written by friends and industry peers. This interest extends beyond business non-fiction to include novels by authors like Eliot Peper, and he actively fosters community around these interests through initiatives like his own book club and promoting events for aspiring authors.
  • Commitment to strengthening the broader startup ecosystem through data sharing and community support. He regularly amplifies resources helpful to founders, such as high-level SaaS benchmark surveys, research on ethical challenges in entrepreneurship conducted with MIT, and discussions on the future of capitalism and startup communities.

Foundry Group operates as both a direct investor in startups and an LP in other venture funds, creating a curated network of like-minded partners rather than just providing capital, while maintaining an unusual flat partnership structure with no associates or analysts where equal partners do all the work themselves. The Boulder-based firm organizes investments around long-lived horizontal themes like "glue" and "protocol" rather than traditional sectors, and has built their brand on radical transparency by publishing playbooks, openly discussing fund decisions, and "open sourcing" their approach through books, blogs, and podcasts.
