Mosaic announced it has raised $18 million in a Series A round led by Radical Ventures to expand its AI-driven platform across private markets workflows and adjacent sectors.
Mosaic is developing an operating system for investors and advisors that automates complex deal modeling processes traditionally handled in spreadsheets. The platform combines deterministic, rules-based calculations with AI-driven data ingestion and agentic workflows to improve speed, accuracy, and consistency in financial analysis.
The company said its technology enables deal teams to complete core analyses such as leveraged buyouts and discounted cash flow models up to 20 times faster, while eliminating common spreadsheet errors. Its platform is already used by major private market institutions, including Warburg Pincus, Bridgepoint, CVC, New Mountain, and Evercore.
Mosaic’s agentic AI feature, Mosaic Autopilot, allows users to initiate financial models via email prompts, automatically generating fully built models within minutes based on supporting documents and firm-specific parameters.
The company plans to use the new funding to expand its engineering, product, customer enablement, and go-to-market teams, with headcount expected to grow significantly by the end of 2026. Mosaic also aims to broaden its reach beyond private equity into investment banking and private credit.
As part of the financing, Ryan Shannon of Radical Ventures and Troy Pospisil, CEO of Ontra.ai, will join the company’s board of directors, while John Megrue of Radical Ventures will serve as a strategic advisor.
Mosaic said its approach differs from traditional AI tools by focusing on deterministic, audit-ready outputs that can be standardized across organizations, enabling better decision-making and institutional knowledge over time.
KEY QUOTES:
“Before Mosaic, thousands of investors (myself included) 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. We built Mosaic so investors and bankers can spend less time linking and more time thinking. Our platform gives users the speed of automation and the reliability of deterministic calculations, so they can trust the analysis every time.”
Ian Gutwinski, Founder And CEO, Mosaic
“When I worked in Investment Banking and Private Equity, I was always shocked at how much time some of the most expensive talent in the world spent trying to fix broken models with sheer brute force. With Mosaic, that same expensive talent can instead spend their time thinking about the crucial decisions that separate good investments from great ones.”
Ryan Shannon, Partner, Radical Ventures
“There’s a ton of noise in the financial services world right now when it comes to AI tools. Unfortunately, the vast majority of these offerings overpromise and underdeliver, and are not delivering real value to firms. Mosaic is a rare exception of a team that deeply understands what the top investment banks, private equity funds, and private credit funds need, and is one of the few products actually delivering value today.”
John Megrue, Vice Chairman, Radical Ventures
“I’m excited to be joining Mosaic’s Board after backing the company early as a personal investor. Mosaic is tackling a complex problem for a market I care deeply about, and I believe Ian and the world-class team he’s assembled around him possess the unique mix of industry experience, technical depth, and relentlessness to actually change embedded behavior that hasn’t evolved in 50 years. Amidst an AI hype cycle, Mosaic is sticking to the first principles of entrepreneurship that I admire: being customer-obsessed and using every available technology and resource – whether AI, workflow, or world-class support – to deliver outcomes that its customers truly value.”
Troy Pospisil, Founder And CEO, Ontra.ai
