Proprietary Deal Flow

Definition

Proprietary deal flow refers to acquisition opportunities that a buyer accesses exclusively or semi-exclusively, outside of a competitive auction process. These deals are often sourced through direct relationships with business owners, referrals from trusted intermediaries, or fireside chats arranged before a formal process launches.

Context

Proprietary deal access is the aspirational outcome of the relationship-building strategies discussed throughout Deal Sourcery. In Ep. 23, Chris Reilly describes the spectrum from broad auctions (wide distribution, many buyers) to narrow processes (selective, few buyers) to fireside chats (pre-process, most exclusive). Firms that earn proprietary access do so through sustained Reciprocal Relationship Building with boutique bankers and COIs.

In Ep. 20, Jake Colognesi describes how Mamba Growth pursues proprietary access to bootstrapped SaaS founders who aren't running processes. These companies "don't need to do anything" — they're profitable and not seeking capital — so proprietary access comes from value-first outreach and trust-building over time, not from intermediary relationships.
