San Francisco Ruby Startup Conference

​Ruby is where startups grow. The companies that scaled on Ruby and Rails are the products we use daily: Shopify, Coinbase, Figma, and Chime are public, and Stripe runs a 50-million-line Ruby monolith. A wave of unicorns is right behind them, from Fin, Gusto, and Persona to Checkr, Apollo and Factorial, and a new generation is shipping leaner than ever: Whop reached a $1.6B valuation with 15 engineers and SurgeAI reached $1.4B run rate, with less than 100 people - both on Rails. The San Francisco Ruby Startup Conference is for people behind the present and the future stories of success on Ruby.

​Three days in the heart of San Francisco for the founders and engineers betting on Ruby. Expect deep technical talks, founder stories, and organized networking sessions that turn into your next hire, co-founder, or open source project.

​Keynote: Garry Tan, President & CEO of Y Combinator

​"People are sleeping a bit on how much Ruby on Rails + Claude Code is a crazy unlock. Rails was designed for people who love syntactic sugar, and LLMs are sugar fiends."

​— Garry Tan

​Garry is a Rubyist, who originally built Bookface, YC's internal platform, on Rails. Since taking over YC in 2023, he's led its fastest-growing and most profitable batches on record. He's joining us to talk about Ruby, startups, AI, and what comes next.

​What to expect:

• ​Talks from engineers and founders shipping Ruby in production
