YC Winter 2026 Startup Rankings #1 - o11 (9/10) š
I'm going through 30+ companies from Y Combinator's Winter 2026 batch and ranking them based on what I'd actually invest in. Here's company #1: o11 What They Do: AI platform for capital markets built directly into Microsoft 365 (Excel, Word, PowerPoint). They're targeting investment banks, hedge funds, and asset managers. Why I'm Bullish (9/10 Rating): 1. They Meet Users Where They Are - Capital markets firms haven't changed workflows in decades - They live in Excel and Word - Most AI companies fail because they ask users to abandon everything and adopt new platforms - o11 just plugs into the tools they already use every day 2. Founder Credibility is Insane - Aryah: Morehead-Cain Scholar, led AI at two major capital markets firms - Ajay: 4x founder, ex-Mayo Clinic AI Lab - Technical depth + domain expertise = rare combo 3. Business Model is a Money Printer - B2B SaaS in fintech = high margins, sticky contracts - Enterprise deals in capital markets = massive contract values - If they land 2-3 major banks, they're set - Switching costs are HIGH once integrated into daily workflows 4. TAM is Massive - Trillions flow through these firms - Efficiency gains = direct bottom-line impact - AI in capital markets is inevitable; question is who captures it What do you think?
