Deal sourcing for family offices: where the flow comes from

Family office deal flow comes mainly from other families, from fund managers offering co-investment, and from the family's own operating network, with investment banks and intermediaries a secondary and more conflicted channel. The surveys agree that sourcing is the weakest part of most direct programmes. BlackRock's 2025 survey of 175 single family offices found 63% reported gaps in deal sourcing expertise, and BNY Wealth's 2025 report recorded a 120% jump in US offices seeking direct deal sourcing. An interviewee in Campden Wealth's 2025 North America report put the practical position plainly: "More or less all our warm leads come from other family offices."

The channels

Peers

Peer networks produce the warmest introductions because the referring family has usually done work on the deal and is often investing itself. A 2024 survey by Bastiat Partners and Kharis Capital reported by CNBC found 60% of family offices view networking with other offices as important and 74% are "eager for more introductions". PwC's 2025 deals study found club deals accounted for 69% of family office transactions in the first half of 2025, which means most direct deals already arrive with another family attached. The organisations through which families meet are described in family office co-investment networks.

Fund managers

For offices with a fund portfolio, the managers in it are the most scalable source of direct exposure. Campden's 2025 report found co-investments make up 8% of the North American private markets book and are increasing, with the opportunities coming through fund managers. Ropes & Gray's 2025 note found deal-by-deal co-investment remains the most common approach, and that managers increasingly accept co-investors who co-underwrite and ask for board seats. Bain's 2026 Global Private Equity Report found the median manager now offers 33 cents of co-investment for every dollar of fee-bearing capital, so on that median a family with $50m in a fund might expect to be shown around $16m of co-investment over the fund's life. The flow is real but it arrives on the manager's timetable, and families that cannot respond within weeks are dropped from the list.

Banks and intermediaries

Sell-side advisers run auctions, and family offices are rarely the natural winner of an auction against a fund with a dedicated team and committed capital. Institutional Investor reported in 2025 that some families use investment bankers "despite the conflicts of interest", while others rely on trusted private equity firms to identify candidates. The 2024 Bastiat Partners survey found 20% of offices named quality of deal flow as a primary concern and that families "may see 10 deals or more for every one that works". Intermediated flow is high in volume and low in conversion.

Proprietary flow

The deals that produce the best outcomes are usually the ones nobody else saw, and they come from the family's own industry. Citi's 2025 report found direct investing engagement was highest in North America at 77%, and SVB and Campden Wealth research reported by Opalesque found most venture-active offices rely on their existing networks for deal flow because the best deals remain hard to access. Proprietary sourcing works when the family is known in a sector as an owner rather than a financier, and when it can move faster than a fund on a deal that suits a long hold. It fails when an office chases deals outside its competence; Institutional Investor quoted a panelist describing a CIO "doing some direct stuff in spaces where he had no expertise".

BlackRock's survey, summarised by Caproasia, found 52% of offices named co-investment and direct deal sourcing opportunities as the external support they most want, ahead of any other service, and only 37% were confident in their deal sourcing. Morgan Lewis noted in 2025 that direct investing increasingly "enhance[s] deal flow through partnerships with funds and other investors". The practical programme that emerges from the data is narrow. It means defining the sectors where the family has an edge and telling managers and peers what the office wants to see, then building the capacity to say yes or no quickly. Once a deal arrives, the terms of sharing it are covered in club deals: how families syndicate, and the work required before committing in direct deal due diligence.
