Summary
Mosaic, an AI-powered SaaS platform specializing in deal model automation, announced a $18 million Series A funding round to expand its footprint across private markets. The New York-based startup, founded by Ian Gutwinski, has positioned itself as the leading digital deal-modeling platform for private equity and is now broadening its addressable market into institutional investment banking.

The company's core value proposition centers on automating the time-intensive infrastructure work of financial modeling. Mosaic's platform generates deal models with near-instantaneous speed using rules-based algorithms that eliminate common Excel-based modeling errors such as formula miscalculations, incorrect linking, and data inconsistencies. By streamlining the mechanical aspects of model construction, the platform allows deal teams to allocate more analytical capacity to higher-order value creation analysis and strategic problem-solving.

A significant strategic milestone accompanies the funding: Mosaic announced a formal partnership with Evercore, a premier independent investment bank. Under this collaboration, Evercore's Financial Sponsors Group—one of the most active advisors to PE firms globally—will lead the platform's initial rollout into investment banking workflows. Neil Shah, Senior Managing Director and Co-Head of Evercore's Financial Sponsors Group, noted that the platform "represents an opportunity to streamline financial modelling, allowing our teams to focus on creative and compelling solutions for our clients." This expansion extends Mosaic's capabilities beyond private equity buyout analysis into M&A advisory, capital markets work, and valuation modeling.

The Series A funding will support Mosaic's development roadmap across multiple investment banking use cases and enhance collaboration with Evercore to refine platform functionality. The company's broader strategic objective reflects industry recognition that automation of routine financial modeling tasks can improve both operational efficiency and work-life balance for junior finance professionals—addressing a persistent pain point in deal-intensive advisory businesses.
