Mosaic is an AI-driven operating system for deal makers in private markets. The platform automates deal modeling analyses historically built and maintained manually in Excel — including leveraged buyouts (LBOs) and discounted cash flows (DCFs) — by combining deterministic, rules-based calculations with AI-powered document ingestion and agentic workflows. Its AI agent 'Mo' allows deal teams to generate MD-ready financial models via email prompt in as little as 5–10 minutes, compared to the weeks such analyses typically take. Mosaic targets private equity firms, investment banks, private credit funds, and hedge funds, and counts Warburg Pincus, Bridgepoint, CVC, New Mountain, and Evercore among its customers. Founded in New York by Ian Gutwinski (formerly 6 years in private equity at Onex Partners), who built the first version as a class project at MIT during his Harvard Business School MBA. The company — legally incorporated as Investor Technology Group, Inc. — raised an $18M Series A led by Radical Ventures in April 2026.
