Person
Creator of the Ruby on Rails web framework and the Omarchy Linux setup; CTO and co-founder of software maker 37signals (Basecamp, HEY).
David Heinemeier Hansson's agent-written Rust port of Campfire served 36,120 room-page requests a second to Rails' 217 in 37signals' own benchmark. A parity harness checks its behavior against Rails, but the numbers are company-run and stop short of production traffic.
Reality
37signals has made hand-written code an exception handled like a Sentry bug and is rebuilding HEY as six native apps on a Rust backend. DHH's line counts come from his own slides, so the policy and the rebuild are what an engineering lead can actually judge.
Reality
David Heinemeier Hansson said in his Rails World keynote that 37signals, the 27-year-old company behind Ruby on Rails, is done writing code by hand. Its stack now follows how well agents write each language, and other teams can measure that on their own code first.
Reality
One programmer ran the same bet on two codebases and got opposite results, which is closer to a controlled test than anything else in the agentic coding argument, and the published dates make it harder to read than it needs to be.
Reality
The company told staff the money went to the Omacom Foundation rather than to a person, and cited Omarchy's rank among its users as the reason. Customers and employees are reading it as a decision about a person anyway.
Reality
Omarchy's patron ledger names twelve individuals and two companies and adds up to the dollar. The nonprofit meant to hold the trademarks has no jurisdiction, entity or headquarters on the record, and that is the part a fleet owner should be pricing.
