Most family offices that hold direct stakes in startups did not get them by cold-sourcing founders. They got them through club deals: writing a cheque alongside an angel syndicate, a lead angel or a venture fund that had already found and priced the round. It comes in three forms: shares taken directly on the cap table alongside a lead, a subscription through an SPV or nominee the lead has arranged, or co-investment rights exercised from a fund position.
This page is written for the family-office principal weighing the route in, and for the angel or syndicate lead deciding whether a family office belongs on the cap table.
The Carry's reading of the club-deal pattern: it endures because each side rents what it lacks. The office rents deal flow, pricing and diligence; the syndicate and its angels rent patient, flexible capital.
A club deal looks like one round on one cap table. It is really three sets of incentives agreeing to share it.
How are family office co-investments structured?
Three structures cover almost all of it. A family office can buy shares directly on the company's cap table alongside a lead investor; it can subscribe through a special purpose vehicle (SPV) or nominee arranged by an angel syndicate or lead; or it can take up co-investment rights offered by a venture fund in which it is already a limited partner.
Direct means the office, or a family member investing personally, sits on the share register in its own name and carries its own documents and diligence: the highest-control, highest-effort route, favoured by single family offices (one family's own operation, as against a multi-family office serving several) with in-house deal teams. The SPV or nominee route pools the office's money with a syndicate's other investors behind a single line on the register; the lead runs the process and the paperwork is standardised. How a one-deal vehicle works in practice is a page of its own. LP co-investment is the quietest route: the fund offers limited partners extra allocation in a specific portfolio company, often at reduced fee and carry, with the manager's work already done.
One structural point matters early. SEIS and EIS income tax relief belongs to individual investors, not entities: GOV.UK sets SEIS at 50% relief on up to £200,000 a tax year and EIS at 30% on up to £1m, and HMRC treats an individual who subscribes through a nominee as the subscriber (VCM10520). A company, a family investment company included, cannot claim it; family members investing personally can. The table above puts the three routes side by side.
Why do club deals dominate family office direct investing?
Because co-investing solves the two problems that stop a family office doing direct venture well: sourcing and diligence. Campden Wealth's research has consistently reported co-investments and club deals as the dominant structure for family-office direct dealmaking. A lead who lives in the market sees the deals and prices them; the office supplies capital without building a venture team it might use ten times a year.
The allocation context explains the appetite. The UBS Global Family Office Report 2026, which surveyed 307 family offices with average assets of roughly $1.3bn, puts alternatives at about 42% of the average portfolio, and finds direct and fund positions within private markets at rough parity, where 2021 skewed to direct (roughly 13% of the portfolio direct against 8% in funds). Campden Wealth's 2025 reporting puts private markets at about 29% of the average family-office portfolio. The picture: substantial exposure, with offices neither abandoning funds nor going it alone. Co-investment is the middle route, deal-level exposure with someone else's engine attached.
What does each side bring to a club deal?
The family office brings capital that can wait; the angel side brings the deals and a view on price.
The office's contribution is patience and cheque flexibility. It has no fund clock forcing an exit in year eight, it can size a cheque up or down without breaking a fund model, and it can follow on or bridge a company between rounds. For a VC lead that makes a family office a comfortable co-investor: the round gets filled without another fund competing for ownership.
The angel or syndicate lead's contribution is the engine: founder networks that produce deal flow, the diligence hours, the pricing discipline of someone doing this weekly, and often a board seat or operator mentoring after completion. The same relationship seen from the angel's seat in a VC-led round is covered separately, as is the way a syndicate organises itself around a lead. One boundary note: sharing a live deal with prospective investors sits inside the UK's financial promotion rules, covered from the lead's side in the guide to setting up a UK syndicate.
Where do interests diverge in a club deal?
In four predictable places: fees, information rights, follow-on behaviour and exit horizon. None is fatal. All are cheaper to surface before completion than after.
- Fees and carry. The lead's setup fee and carry pay for the sourcing and the diligence. A large family-office cheque sometimes tries to come in around the structure, straight onto the cap table at no fee, and whether the lead wears that depends on how badly the round needs the money. Both positions are rational; the friction is real.
- Information rights. An office running consolidated reporting wants data a small syndicate rarely negotiates for. Whoever wins that negotiation, the founder produces the reports, so rights tend to get rationed by cheque size.
- Follow-on behaviour. A deep-pocketed office can support a bridge or a down round that dilutes everyone who does not follow. Knowing in advance who intends to keep supporting the company changes how the angels read the risk.
- Exit horizon. A venture fund has a life and must return capital; an office can hold indefinitely; an angel may want liquidity at the first serious offer. The same secondary approach can look like a win, an irritation or a threat, depending on the seat.
What should each side check before sharing a cap table?
Both sides are testing the same thing from opposite directions: whether the other party's incentives hold for the life of the deal, which in early-stage venture is closer to ten years than five.
For the office, the questions are about the lead. Who sourced and priced the round, and what do they earn from it? Is the lead's own money in on the same terms? What are the carry, the fees and the reporting rights, and who decides inside the SPV, if there is one, when the follow-on or the secondary offer arrives?
For the angel or lead, the questions are about the cheque. Does the office decide at the pace of one principal or of a committee? Does the money come with appetite for follow-ons, or end at the first round? How did the office behave the last time a portfolio company hit trouble? References travel fast in a small market, in both directions.
A closing note on what this page is and isn't. It is general information about how co-investment structures work, not financial advice, and not a suggestion that any family office, angel or syndicate arrange a deal one way or another. Whether any route suits you turns on your circumstances, your tax position and the specific deal. Check the current scheme rules at GOV.UK and take advice from an FCA-regulated adviser before committing capital.
Frequently asked questions
Do family offices co-invest with angel syndicates?
Yes, commonly. Campden Wealth's research has consistently reported co-investments and club deals as the dominant structure for family-office direct deals. A syndicate gives the office sourced, priced and diligenced deals without the cost of an in-house venture team; the office gives the syndicate a larger, more patient cheque. The relationship is usually structured through an SPV or nominee run by the syndicate lead, or with the office taking shares directly on the cap table alongside the syndicate.
What is a club deal?
A club deal is a private investment made jointly by a small group of investors, typically a family office alongside angels, a syndicate or a venture fund, rather than by one institution alone. Participants invest on broadly the same terms in the same round, with one party, usually the lead, sourcing and pricing the deal. In UK startup investing the club generally holds shares either directly on the cap table or through a special purpose vehicle or nominee.
Can a family office claim SEIS or EIS relief on a co-investment?
Not as an entity. SEIS and EIS income tax relief belongs to individual investors: a company, including a family investment company, cannot claim it, and trustee subscriptions do not qualify. Family members who subscribe personally can claim, and HMRC treats an individual who subscribes through a nominee as the subscriber. The detail is on GOV.UK and in HMRC's Venture Capital Schemes Manual, and structuring around the relief is a matter for a qualified tax adviser.
What does a family office check before co-investing with an angel or VC?
The questions are usually about incentives as much as the company: who sourced and priced the deal and what they earn from it, whether the lead has invested on the same terms, what fees and carry the structure carries, what information rights come with the cheque, and who decides on follow-ons or a sale inside any SPV. Offices also weigh how the lead behaved in past deals that went sideways, just as leads take references on how an office behaves when a company hits trouble.
Is this article financial advice?
No. It is general information about how family-office co-investment is structured in the UK, not financial advice and not a recommendation of any investment, structure or route. Whether co-investing suits a family office or an angel depends on circumstances, tax position and the specific deal. Check the current rules at GOV.UK and take advice from an FCA-regulated adviser before committing capital.
