Summary
Mosaic, an AI-driven deal modeling platform designed for private markets, has secured $18 million in Series A funding led by Radical Ventures. The capital infusion will fund product expansion across private equity workflows and accelerate the company's entry into adjacent verticals including investment banking and private credit markets.
The platform addresses a fundamental inefficiency in institutional investment workflows by automating deal analyses historically constructed and maintained manually in Excel spreadsheets. Mosaic combines deterministic, rules-based calculations with AI-powered data ingestion and agentic workflows to standardize analyses such as LBOs and DCFs while reducing the operational burden on deal teams. According to the company, customers report completion of core deal analyses up to 20 times faster than traditional methods while completely eliminating spreadsheet "mis-link" errors inherent in manual modeling.
Mosaic's customer base reflects substantial traction among top-tier institutional investors. The platform is currently deployed by leading private market firms including Warburg Pincus, Bridgepoint, CVC, New Mountain, and Evercore. During 2025, the company achieved significant market adoption, being selected by five of the top ten global private equity firms and two of the world's most prolific investment banks as their preferred AI-driven deal modeling solution.
Founder and CEO Ian Gutwinski framed the market opportunity as addressing a widespread productivity gap: "Before Mosaic, thousands of investors spent hundreds of hours iterating on generic spreadsheet templates to rebuild and refine the same calculation scaffolding for each new investment opportunity. Yet all those hours do nothing to improve investment outcomes." This positioning suggests Mosaic targets the redeployment of analyst time from mechanical tasks toward higher-value investment analysis and judgment.
The Series A financing validates investor confidence in Mosaic's solution architecture and market positioning within the institutional deal-making ecosystem, with Radical Ventures' backing indicating institutional venture capital recognition of the fintech opportunity in private markets infrastructure.
