o11

o11 is a Y Combinator (W26) startup building AI agents that live inside the enterprise apps finance teams already use - Excel, PowerPoint, Word, and Google Workspace. Rather than answering questions in a sidebar, its agents do the work: generating three-statement models, investment committee memos, CIMs, buyer lists, and decks from natural-language prompts. Its customers include investment banks, private equity firms, hedge funds, and asset managers.
