Why HF0 Is a New Way to Build AI Companies

Can founders 10x their progress in 12 weeks? In this episode, I speak with Dave Fontenot, Founder of HF0, a groundbreaking startup residency that’s redefining how AI companies are built. HF0’s model—part hacker house, part monastic focus—is based on the idea that startups grow fastest when founders eliminate every distraction and operate in uninterrupted flow. Dave explains how the residency model is helping founders make “two years of progress in 12 weeks,” why the most dangerous distraction is the second most important thing in your business, and how recursive subtraction leads to breakthrough realizations. We discuss what true flow looks like, how competition in AI has changed company-building forever, and why the next generation of founders will work like athletes in training camp.

Highlights:

• How HF0 redefined startup acceleration by replacing addition with subtraction
• Why the most insidious distraction for founders is the second most important thing in their business
• How residency-based company building leads to “a year or two of progress in 12 weeks”
• The psychology behind avoidance—and why even elite founders escape the hardest problems
• How AI changes the calculus of startup speed by compressing iteration cycles
• Why “flow compounds” and how context continuity multiplies productivity
• The secret to building software 10x faster: protect the compound return of uninterrupted work
• Why empathy and trust—not specs—create products with soul
• How HF0’s model is spreading globally, spawning a new generation of residencies
• Practical ways to create “HF0 Lite” in your own life—down to ordering routines and workspace design
