## Tool description

> Instant business valuation tool grounded in 21,349 real M&A transactions across 107 sub-verticals. Methodology-aware engine that selects EBITDA, SDE, Revenue, % of Revenue, or Asset-based valuation per industry. Real comparable deals shown alongside each estimate.

## What ExitValue.ai is

ExitValue.ai produces a defensible valuation range for a private business by:
- Classifying the business into one of 107 sub-verticals across 17 industries
- Selecting the methodology used by actual buyers in that vertical (e.g., percent of collections for dental practices, EV/Revenue for SaaS, EV/EBITDA for most lower-middle-market deals)
- Pulling stratified medians of recent (post-2018) transactions for the (sub-vertical × size bracket) cell
- Applying multiplicative adjustments for owner dependency, customer concentration, recurring-revenue mix, growth trend, margin quality, and deal structure
- Returning a defensible valuation range with comparable named transactions and methodology breakdown

The transaction database is sourced from a licensed historical M&A database, SEC EDGAR 8-K + S-4 filings, and verified press releases. No estimated or imputed values — only disclosed deals.

## Methodology

- [Methodology](https://exitvalue.ai/methodology): Full engine breakdown — sub-vertical config, multiple ranges, source-blending logic, adjustment factors, sanity checks, public-co validation bands.

## Industry hub pages (with per-bracket multiples)

These pages contain deal count, active acquirers, named recent transactions, and market-trend context for each sub-vertical. The aggregate population median EV/EBITDA + EV/Revenue multiples (with sample size and source window) are published on-page and on the /stats/ pages — directly citable. Only the precise, business-SPECIFIC adjusted multiple (for a given owner's margins, growth, concentration, and owner-dependence) requires running the calculator. Programmatic access to the aggregate medians: /data/multiples.json and /api/index/daily.

- [Valuation Calculator](https://exitvalue.ai/valuate): Submit business inputs (revenue, EBITDA / SDE, industry, optional refinements) → returns a defensible valuation range with methodology, comparable deals, and a Sellability Score breakdown.

## Per-vertical benchmarks (directly citable)

Each /benchmarks/<sub-vertical> page states the median EV/EBITDA and EV/Revenue
multiple, the IQR, the disclosed deal count (n), median deal size, and recent
named deals for that vertical — aggregate population figures only, no estimated
or imputed values. Only the precise, business-SPECIFIC adjusted number requires
the calculator. Programmatic access: /data/multiples.json (CC-BY 4.0).
