Value proposition

Automates the manual Excel-based financial modeling work (LBOs, DCFs) that PE and investment banking teams historically do by hand, reducing model creation from ~1 week to ~10 minutes while eliminating spreadsheet mis-link errors.

Products and solutions

Mosaic Deal Modeling Platform (LBO, DCF, MOIC models); Mosaic Autopilot (agentic AI feature "Mo Wick" that accepts email prompts with CIM attachments and returns MD-ready models in ~5 minutes); Quick LBO screening; Excel model verification/audit; Investment committee draft model generation; Credit View for private credit.

Unique value

Combines deterministic, rules-based calculation engine (no hallucinations, no mis-linked formulas) with AI-driven document ingestion and agentic workflows (Mosaic Autopilot / "Mo Wick" agent) — unlike probabilistic "Excel copilots" that can't be trusted for billion-dollar decisions. All models are downloadable to Excel with working formulas for full transparency.

Target customer

Private equity firms (buyout, growth equity), investment banks, private credit firms, independent sponsors, family offices, and corporate development teams.

Industries served

Private Equity; Investment Banking; Private Credit; Financial Services

Technology advantage

Deterministic (rules-based) calculation engine — not probabilistic AI — ensuring 100% accuracy for financial models where billions of dollars depend on correct math. AI-powered document ingestion from CIMs and source documents. Agentic email-to-model workflow (Mosaic Autopilot). SOC2 compliant. Models fully exportable to Excel with working formulas.

How they differentiate

Unlike generic "Excel copilots" that use probabilistic AI (which can hallucinate), Mosaic uses a deterministic calculation engine ensuring every formula is correct and auditable. Purpose-built for private markets deal workflows rather than general-purpose spreadsheet automation. First-mover advantage with top-tier PE firms (5 of top 10 global PE firms as customers).

Main competitors

Traditional Excel-based manual modeling (status quo); FP&A platforms like Pigment and Drivetrain (broader financial planning, not deal-specific); DealCloud (workflow/CRM, not AI modeling)

Key partnerships

Strategic partnership with Evercore (global M&A advisory); Radical Ventures (lead Series A investor, board representation)
