ProCloser.ai was founded by Aaron Whittaker to give business owners usable data before they choose an M&A advisor. Most owners pick a firm on a referral and a pitch deck. ProCloser publishes the deal ledger, firm profiles, and valuation benchmarks that should have been on the table first.
Aaron has spent his career in search and digital growth for professional services firms. He built ProCloser's Tech M&A Deal Index, the advisor directory, and the TrustRank methodology that tracks how often each firm is cited by AI search engines.
How the research is produced
Every guide, ranking, and firm profile on this site is produced by the ProCloser Research team from the firm's own deal data, directory records, and AI visibility tracking, and reviewed by Aaron before publication. Guides are updated as the underlying deal data changes. Rankings follow the TrustRank methodology. If you spot an error or have data that belongs in the next update, use the contact page.
