Search funds, their investors and the deal advisers
Your existing audience, listed here because it is also a paying segment. Searchers, the investors who back them, and the corporate finance boutiques and law firms that live off the same transactions.

Who signs: the searcher, the fund partner, the corporate finance principal, and the law firm partner who owns the succession practice.
