How OpenAI CEO Sam Altman Applied to YC's First Batch in 2005

Early Days at Stanford and Loopt

• 🧠 Sam Altman was a sophomore at Stanford University, working in an AI lab when he started his project, Loopt.
• 💡 Loopt began as a dorm room project and, according to Altman, would not have evolved into a company without the support of Y Combinator.

Discovering Y Combinator

• 🔍 Altman learned about the Summer Founders Program (YC's initial name) from Blake Ross, co-founder of Firefox, who posted about it on "the Facebook" at the time.
• 📚 He was already familiar with Paul Graham through his influential essays, which had a significant following.

The Interview Experience

• ✈️ Altman took a red-eye flight to Cambridge for the interview, staying on a friend's couch before walking to the Garden Street office.
• ⏳ The interview was a 40-minute session, described more as an office hour session with brainstorming and a demo, rather than a traditional interview.
• 🤫 Jessica Livingston, one of the four YC partners, was initially a secret member, with her affiliation kept private during the early stages.
• 📝 The application form initially suggested only "close calls" would be interviewed, leading applicants to believe they were on the bubble, though everyone was ultimately interviewed.

The Funding Offer

• 📞 Paul Graham called Altman during dinner on an old Palm Trio to offer funding, a moment Altman describes as a life pivot.
• ✅ Altman accepted the offer immediately, despite Graham's playful comment about it being an "intelligence test" to accept quickly.

Reflections on the First Batch

• 🚀 The first YC batch involved only eight companies, making the selection process highly competitive and memorable.
• 🤝 The overall experience was an all-day event that included hanging out with other companies and a group dinner, fostering a unique community atmosphere.
