Zarna builds AI associates for private capital, autonomous agents that handle deal work for private equity and M&A advisory firms. By connecting to firm data (CRM, shared drives, past deals, board decks), Zarna's agents tear down CIMs, build LBO models, generate tear sheets, draft IC memos, and update the CRM. The goal is to free investors from repetitive tasks so they can focus on judgment and relationships. Founded by four UC Berkeley alumni who were embedded as forward-deployed engineers inside AEA Investors, Zarna is part of Y Combinator's Fall 2025 batch.
