About Cornerstone Business Valuation & Brokerage

Cornerstone Business Valuation & Brokerage leverages on our valuation and structuring expertise gained from 25 years of investment banking on Wall Street and 10 years as an M&A professional with the largest business brokerage platform in North America. Our clients are owners of privately held businesses looking to maximize their Exit Money, the sum of (1) Enterprise value of their businesses, (2) the associated real estate and (3) the trapped, net working capital in the business that stays with the Seller in an asset sale transaction.

The three core principles of the Cornerstone operation are confidentiality, professionalism and success.

METHODOLOGY

What we observe

DealLedger publishes what is publicly displayed. Broker records aggregate every observed listing tied to this firm across our sources. Counts above reflect distinct listings observed, not closed transactions confirmed by the broker.

We do not have direct visibility into which listings sold. When a listing stops appearing in our scrapes, we mark it as no longer observed — but we do not claim it sold. Some close; some withdraw; some are re-listed under a new ID; some are simply missed by our scraper. We surface the observation; you draw the conclusion.
