Family offices manage the wealth of a single wealthy family or a small group of families. They've become important investors in private companies, real estate, private equity funds and venture capital. They're also notoriously hard to find. Many have no website, no listed phone number and no interest in being contacted by strangers.

This guide explains how family offices work, how to find ones that fit what you're raising for or selling, and how to approach them in a way that doesn't get you ignored.

Single vs multi-family offices

  • Single-family office (SFO): serves one family. Often has a small team: a chief investment officer, a few investment professionals and administrative staff. Decision-making ultimately sits with the family.
  • Multi-family office (MFO): serves several families, often operating more like a wealth management firm. Usually more accessible and more structured, with formal investment processes.

For direct investments in private companies, SFOs are often the more interesting target because they have more flexibility. MFOs are often more relevant for fund managers raising capital.

Why family offices matter

Family offices have several traits that make them attractive investors:

  • Patient capital. Without the fixed fund life of a PE or VC fund, they can hold investments for a long time.
  • Flexible structures. They can invest in equity, debt, preferred structures or partnerships.
  • Industry expertise. Families that built a business in a particular sector often prefer to invest in that sector.
  • Speed. With a small team and direct access to decision-makers, some can move quickly.

They also have downsides: unpredictable priorities, small teams that can't evaluate many deals, and decisions that sometimes depend on family dynamics.

Step 1: Know what you're offering

Family offices are approached constantly. Before you start looking, define what you're offering and which family offices would plausibly care:

  • A direct investment in a company? Which sector, stage and size?
  • A co-investment alongside a fund or sponsor?
  • A fund commitment for a private equity, venture or real estate fund?
  • A business for sale that might suit a family office as a long-term holding?

Each of these appeals to a different type of family office, and sometimes a different person inside the same one.

Step 2: Where to find family offices

Deal and fund disclosures

When family offices invest, it sometimes becomes public: as a named investor in a funding announcement, a co-investor in a PE deal, an LP in a fund disclosed in a filing or press release, or a buyer of a business. Track these. A family office that has done two deals in your sector recently is a much warmer target than one found in a generic list.

Regulatory filings

In the US, family offices that meet the SEC's definition are generally exempt from investment adviser registration, so they often don't appear in adviser databases. But their investment vehicles can show up in filings. Form D filings sometimes list related persons associated with investment vehicles. Large family offices with significant US public equity holdings may file 13F reports. Our Form D search guide explains how to look.

Operating company connections

Many family offices were created after a family sold a business. If a well-known founder sold a company in your industry, there's a good chance a family office or personal investment vehicle followed. News of large private company sales is a useful lead source.

Professional advisers

Private banks, wealth managers, estate lawyers, accountants and tax advisers serve family offices. They won't hand over client lists, but if your opportunity is credible, some will make introductions.

Events and networks

Family office conferences and private investor networks exist in most financial centres. Some are worthwhile, others are mainly paid opportunities to pitch to service providers posing as investors. Check who actually attends before paying.

Paid databases

Several data providers sell family office databases. Quality varies a lot. Family offices change staff, priorities and contact details frequently, and some databases include investment firms that aren't really family offices. Treat database lists as a starting point and verify.

LinkedIn

Search for titles such as "chief investment officer" and "director of investments" combined with "family office", filtered by location. Many family office professionals are on LinkedIn even if the office itself has no public presence.

Step 3: Work out their mandate

Before contacting a family office, find out as much as you can about what they invest in. Useful clues:

ClueWhat it tells you
Source of family wealthLikely sector preferences and expertise
Past deals and co-investmentsStage, size and structure preferences
Team backgroundsPE-trained teams often do direct deals; wealth management backgrounds suggest fund investing
LocationMany prefer investments in their home region
Public statements or interviewsStated themes, such as impact or real assets

Step 4: Get introduced

Warm introductions work far better with family offices than cold outreach. Good routes:

  • investors already in your deal or fund,
  • other founders or managers the family office has backed,
  • lawyers, accountants and bankers who work with them,
  • other family offices, who often share deals with each other.

Family offices value discretion and trust. An introduction from someone they respect carries a lot of weight.

Step 5: If you must reach out cold

Cold outreach can work if it's specific and respectful. Keep it short, explain why you're contacting this family office specifically and make an easy ask.

Example cold note

Dear Ms. Laurent,

I noticed your office co-invested in the acquisition of a regional food packaging business last year. We're acquiring a similar business in the same region: a $4M EBITDA flexible packaging converter, founder-owned, with long-term customer contracts.

We've committed equity from our own fund and are inviting a small number of co-investors with sector experience. Would a 20-minute call to share the investment summary be useful?

Details are illustrative.

What family offices look for

  • Alignment: managers and founders with meaningful personal capital at risk.
  • Trust: a track record, references and transparency.
  • Fit: sector, size and structure that match their goals.
  • Control or influence: some want board seats or governance rights; others prefer passive roles.
  • Reasonable fees: family offices are often sceptical of high fee structures, especially for funds.
  • Discretion: many dislike publicity around their investments.

Common mistakes

  • Mass-emailing a purchased list. Family offices talk to each other and remember spam.
  • Pitching opportunities far outside their mandate.
  • Pushing for quick decisions. Many take time and involve family members.
  • Over-promising returns.
  • Ignoring the gatekeeper. Assistants and junior team members often decide what reaches the CIO.

Building a family office list that's actually useful

The most effective lists are small and well-researched: 50 to 150 family offices, each with a note on why they fit, recent relevant activity and a potential introduction path. That takes time to build, but it produces meetings. If you'd like a researched family office list tailored to your deal or fund, we can build one.

Direct deals vs fund commitments

How you approach a family office depends on what you're offering. The two most common opportunities, direct deals and fund commitments, are often evaluated by different people using different criteria.

Direct deal or co-investmentFund commitment
Who usually evaluates itDirect investment team or the principal personallyCIO or external investment adviser
What they focus onThe company, valuation, governance, control rightsManager track record, strategy, fees, alignment
Typical decision timeCan be fast for a clear fitOften slower, with formal diligence
Common objectionsToo small, wrong sector, no board seatFirst-time fund, fees too high, fund too small

Ask early who in the office handles opportunities like yours. Sending a fund pitch to someone who only does direct deals, or vice versa, wastes time and can leave a poor impression.

Following up without being a nuisance

Family offices often take weeks to respond, and silence doesn't always mean no. A reasonable rhythm is a polite follow-up after two weeks, another after a month, and then periodic updates when you have meaningful news, such as a deal closing, a new investor joining or a strong quarter. Each follow-up should add something new. "Just checking in" emails rarely help. A short note sharing progress gives them a reason to re-engage.

Respecting privacy

Many families value their privacy highly. Never share the names of family office investors, even with other prospective investors, without explicit permission. Be careful about publicising an investment or naming a family office in a press release unless they've agreed. Mishandling discretion is one of the quickest ways to lose a family office relationship, and the family office community is small enough that word travels.

Frequently asked questions

A private firm that manages the investments and often the wider financial affairs of a wealthy family (single-family office) or several families (multi-family office).

Do family offices invest in startups?

Many do, either directly or through venture funds. Interest varies widely, so check each family office's past activity.

How do I contact a family office?

Ideally through a warm introduction from someone they trust. Otherwise, a short, specific note explaining why the opportunity fits their known investments.

Are family office databases reliable?

They're a useful starting point, but contacts and mandates change often. Verify every entry and research recent activity before reaching out.
