Family offices are the largest allocator audience in alternatives, and the least visible one. They discover managers through networks, platforms, and referrals rather than public processes, and they vet with an endowment-trained lens: team quality first, structure and tax efficiency close behind, and a deep skepticism of anything that looks expensive, illiquid, and undifferentiated. Here is how the discovery and vetting actually work, in the words of the family office CIOs themselves.
Family offices now sit at the center of the alternatives market. On iConnections, they are the largest single share of the allocator audience: at Global Alts Europe, single family offices alone are 29% of expected allocators, and multi-family offices another 15%. Yet for most fund managers, the family office channel remains the hardest to read: no RFPs, no public mandates, and a decision process that happens almost entirely behind closed doors.
How do family offices discover new managers?
Family offices do not discover managers through databases alone. The channel mix is networks, referrals from other LPs and GPs, platforms where they can search on their own terms, and events where they control the agenda.
The discovery behavior is active, not passive. On iConnections, family offices are the largest share of the allocator base running searches and viewing fund profiles: part of the roughly 70,000 allocator-initiated searches on the platform every 90 days and more than 250,000 LP-to-GP profile clicks a year. Nearly half of live event meetings are allocator-initiated, which means family offices are frequently the ones requesting the meeting.
The practical implication for managers: family offices cannot call what they cannot find. A complete, specific, current fund profile is the entry ticket to a channel that runs on quiet, self-directed research.
What do family offices look for first?
Team quality, before everything else. Michel Del Buono, CIO of a16z Perennial, the family office Andreessen Horowitz built for its founders, put it in one sentence on stage at Global Alts New York 2026: “The only thing worse than 2 and 20 is 100 and zero.” His warning to family offices chasing direct deals to save on fees: look at the quality of the team first, because saving a few thousand dollars to get a worse investment is not a good trade.
After team, structure. Del Buono’s first-principles build at Perennial was explicitly endowment-style: bring the best practices of institutional asset management, from how the portfolio is structured to fee and tax efficiency, and minimize the headwinds of the traditional fund-of-funds approach. For taxable family office capital, he argues structure is alpha: capturing even half of the 500 to 600 basis point gross-to-net spread in a strategy like real estate can move a portfolio up a full quartile without needing to out-pick the market.
How deep does the vetting go?
Deeper than most managers expect, and on different dimensions than institutional RFPs.
Del Buono’s vetting lens runs through tax and structure first. His example: the same 16% headline return can net 16% in tax-aware real estate or 4% in private credit for a taxable investor, and almost nobody reports post-tax returns, which is why he argues tax-aware exposure should be the real benchmark for family capital. Tax-aware strategies, he noted, grew from roughly $10B to $150B in 24 months, a repeatable structural edge that requires no manager-picking skill at all.
On directs and co-invests, the vetting is structural too: he warns against shells of shells (L1, L2, L3 structures where you cannot tell who controls the entity or how distributions flow) and his advice to family offices is blunt: unless you know exactly who controls the vehicle, leave it to professionals.
And on portfolio construction, the one rule he says every veteran venture LP agrees on: vintage diversification. Returns concentrate in a few 10 to 15x vintages, and timing them is basically impossible.
How big does a family office have to be to run this playbook?
Del Buono puts a number on it: the Goldilocks zone for a multi-asset single family office is roughly $20 to $30B in AUM. Below $1 to $2B, he argues, a diversified single family office is hard to run properly, and the model shifts toward multi-family offices or outsourced structures.
For managers, that sizing reality explains the channel’s shape: thousands of family offices, a wide dispersion in sophistication, and a small number with true institutional infrastructure. The ones in between are exactly the allocators who rely most on platforms and trusted referrals to do their discovery.
What should managers do differently for family offices?
Four adjustments follow from how family offices actually vet.
Lead with the team, not the fee story. The CIO lens is quality first; a cheap version of a weak team loses to a fairly priced strong one.
Show the structure, not just the returns. Family offices managing taxable capital evaluate gross-to-net drag, so managers who can speak to tax and structural efficiency sound different from those who cannot.
Be findable where they search. The largest allocator audience in alternatives does its discovery quietly, on platforms and through networks, not through public processes.
And respect the relationship horizon. Family offices are not quarter-to-quarter capital; the same CIOs who vet hard also stick through drawdowns when the fit is real.
Frequently asked questions
How do family offices find fund managers?
Through networks, referrals, and platforms where they can search on their own terms. Family offices are the largest allocator audience on iConnections (29% single family offices and 15% multi-family offices at Global Alts Europe), where allocators run roughly 70,000 searches for managers every 90 days.
What do family offices look for in a fund manager?
Team quality first, then structure. Michel Del Buono, CIO of a16z Perennial, puts it as: the only thing worse than 2 and 20 is 100 and zero. For taxable capital, post-tax, post-fee outcomes and structural efficiency matter as much as headline returns.
How do family offices vet managers differently from institutions?
They apply endowment-style diligence (team, structure, vintage diversification) with an added tax and structure lens, and deep structural scrutiny of directs and co-invests, including who actually controls the vehicle and how distributions flow.
Are family offices active allocators to emerging managers?
Yes. Family offices are the largest share of the allocator base on iConnections, and nearly half of live event meetings on the platform are allocator-initiated.
The bottom line
Family offices are the biggest, quietest allocator audience in alternatives. They discover through networks and platforms, vet like endowments with a taxable-capital lens, and reward managers who lead with team quality and structural honesty. The channel is not mysterious; it is just self-directed, which means the managers who get found are the ones who made themselves findable.
