Radical Ventures led the round. Troy Pospisil, the founder and chief executive of Ontra.ai, also invested. No valuation was disclosed.

What Mosaic does
Mosaic's platform automates deal modelling that investors and bankers have traditionally built in spreadsheets. It combines rules-based calculations, which the company says are repeatable and auditable, with AI workflows that take in inputs automatically. It also says its approach removes the broken-link errors that are common in spreadsheet models.
A product called Mosaic Autopilot, released in 2025, is an agent that takes an emailed prompt, optionally with source documents such as a confidential information memorandum, applies a firm's default assumptions and returns a model in about five minutes, according to the company's announcement.
Customers and claims
The announcement names Warburg Pincus, Bridgepoint, CVC, New Mountain and Evercore as users. It says Mosaic was selected by five of the top ten global private equity firms and two major investment banks in 2025, and that the platform is used by thousands of finance professionals.
The company says core analyses such as leveraged-buyout and discounted-cash-flow models run up to 20 times faster, and that a model-preparation process can fall from about a week to about ten minutes. It also cites more than 350,000 hours saved and $5.6tn in assets under management at firms using the product. These figures come from the company, and the sources did not describe independent verification.
Use of the funds
Mosaic said it will spend on engineering and product, on training investors and bankers to use the platform, and on go-to-market work across private equity, private credit and investment banking. Pulse 2.0 summarised this as expanding the engineering, product, customer-enablement and go-to-market teams.
The company said the planned investment in people over the next twelve months is roughly an order of magnitude greater than its total investment over its four-year history. Longer term, it wants to extend into front- and middle-office work such as portfolio monitoring, valuations, reporting and hold-or-sell analysis.
The people behind it
Ian Gutwinski is the founder and chief executive, and the blog says the company has been operating for about four years. The company's blog says he spent about a decade in private equity and investment banking. Mosaic lists offices in New York and Toronto without saying which is its headquarters, and it did not give a headcount or total funding.
Pospisil said Mosaic is sticking to the first principles of entrepreneurship that he admires, according to the company's blog and Pulse 2.0.
