A proprietary deal is an investment opportunity that a PE firm sources directly through its own relationships and outreach, without competing against other buyers in an intermediary-led auction. The seller and the PE firm negotiate bilaterally, often before the company ever enters a formal sale process. In a market where broadly auctioned deals drive up purchase prices, proprietary sourcing is one of the few sustainable edges a GP can develop.
The economics are straightforward. In a competitive auction, multiple PE firms bid on the same asset, and the winner is typically whoever pays the highest price (or offers the most seller-friendly terms). This dynamic compresses returns at entry. A proprietary deal removes the competitive pressure. The PE firm negotiates directly with the owner, often at a valuation that reflects fair value rather than auction-inflated pricing. The difference in entry multiple between an auctioned deal and a proprietary one can be one to two turns of EBITDA, which on a $20M EBITDA company translates to $20-40M in enterprise value. That is money the fund does not need to spend.
Beyond price, proprietary deals offer advantages in process quality. With no competing bidders imposing timeline pressure, the PE firm can conduct more thorough due diligence. The seller, who has chosen to engage with this specific buyer, is more likely to be transparent and collaborative. The relationship between buyer and seller, which will matter enormously post-close when the seller often stays involved as an advisor or minority equity holder, starts on a stronger foundation.
Building proprietary deal sourcing capability is a long-term investment. It starts with sector specialization. A PE firm that becomes known as the buyer of choice in a specific industry, the firm that understands the business, respects the culture, and has a track record of successful outcomes, will receive direct inquiries from owners who want to sell to someone who “gets it.” This reputation takes years and multiple successful transactions to build, which is why emerging managers often struggle with proprietary sourcing early in their lifecycle.
The practical sourcing infrastructure includes direct outreach programs (systematically contacting business owners in target sectors), intermediary relationships (cultivating accountants, estate planners, and business attorneys who advise private company owners on succession and liquidity), industry involvement (attending trade shows, joining industry associations, speaking at conferences), and portfolio company networks (leveraging management teams and board members for introductions to peers and competitors).
For fund managers in fundraising, the proprietary sourcing narrative is one of the most scrutinized claims LPs evaluate. Saying “we source proprietary deals” in a pitch deck is easy. Backing it up with data, specific examples, and a documented sourcing process is what differentiates credible claims from marketing language. LPs will ask for the breakdown: what percentage of deal flow is proprietary versus intermediated, how many closed transactions were sourced proprietarily, and what the return differential has been between sourcing channels. Having real answers to those questions strengthens the fundraise materially.
Frequently Asked Questions
Why are proprietary deals more attractive than auctioned deals?
Proprietary deals typically result in lower purchase prices because there is no competitive bidding dynamic. They also provide more time for due diligence, allow the buyer to build a deeper relationship with the seller before closing, and often result in smoother post-acquisition transitions. According to multiple PE industry studies, proprietary deals have historically generated higher returns on average than auctioned transactions.
How do PE firms source proprietary deals?
The most effective proprietary sourcing comes from sector specialization and relationship-building over years. Specific tactics include direct outreach to business owners in target sectors, cultivating referral networks among accountants, attorneys, and wealth advisors who serve private company owners, attending industry conferences and trade shows, leveraging portfolio company management teams for introductions, and building a reputation as the buyer of choice in a specific niche.
What percentage of PE deals are truly proprietary?
Claims of proprietary sourcing are common in PE marketing materials, but truly bilateral deals where no other buyer was considered are rarer than advertised. Many deals described as proprietary actually had limited competition or a pre-emptive bid before a formal process launched. Realistically, 15-30% of middle-market deals are sourced through genuinely proprietary channels, depending on the firm's sector focus and relationship depth.
