Family offices in startup investing: where they are and what they fund

• 8,385 family-office records: 25% of US startup-investor records.
• 33% of startup investors outside CA, NY and MA are family offices, vs 12% inside them.
• Texas: 43% family offices; Dallas metro: 65%.
• Only 109 family-office records list a stage, so warm intros and direct questions do the work.
• Those that list a check size skew large: median minimum $2M.

Key findings

• 8,385 of the 33,282 US startup-investor records in our database (25%) are family offices or people who work at one.
• Family offices are far more prominent outside the coastal hubs: they make up 33% of startup-investor records outside California, New York and Massachusetts, against 12% inside those three states.
• In Texas, 711 of 1,654 startup-investor records (43%) are family offices. In the Dallas metro it is 65%.
• Only 109 family-office records (1.3%) list the stages they invest in. Family offices rarely publish a thesis, which is why founders overlook them.
• Those that do list a check size skew large: the median minimum is $2M, and 71 of the 109 with a check size start at $1M or more.

Why family offices matter to founders outside the hubs

A family office manages the wealth of one family, or a few. Some are large institutions with investment teams; many are small, run by a founder who sold a company or a family that built a regional business. They invest on their own timeline and answer to no outside limited partners. For a founder in Dallas, Atlanta or Chicago, the local family office is often the most important capital source that never shows up on a venture list. Read the plain-English definition in our family office glossary entry.

The data backs that up. Venture firms concentrate in a handful of coastal metros. Family offices are spread much more evenly, and in several large metros they outnumber every other kind of startup investor in our database combined.

Where family offices are, by state

Share is the family-office share of all startup-investor records in that state.

New York has the most family-office records in absolute terms, but they are a fifth of its startup investors. In Texas, Connecticut, New Jersey and Florida, family offices are well over a third. In California they are 7.3%, because venture firms dominate there.

Family offices by metro

Dallas, Charlotte, Houston and Atlanta stand out: in each, family offices make up about half or more of startup-investor records. If you are raising in one of those metros and only pitching venture firms, you are skipping most of the local capital in our data.

What family offices say they fund

Most family-office records do not publish stages, sectors or check sizes. Of the 8,385 records, 109 list a stage. Among those, 96 include seed, 71 include Series B or later, 57 include Series A and 17 include pre-seed. Of the 109 records that list a check size, 32 start between $250K and $1M and 71 start at $1M or more; the smaller bands have fewer than 10 records each and are not shown.

Read that as a signal, not a census. Family offices that publish a range tend to be the larger, more institutional ones. Smaller offices may write angel-sized checks into local companies without publishing a range at all. The reliable way to learn is to ask, ideally through someone who already knows the family.

How to approach a family office

1. Start local. Use the metro table above. Family offices usually prefer companies they can visit, and local pride matters.
2. Find the warm path. Family offices take few cold pitches. Their accountants, lawyers, bankers and portfolio founders are the usual route. Our warm intro playbook shows how to map those paths.
3. Match the family's history. A family that built a logistics or healthcare business often backs founders in that industry. Research the source of the wealth before the meeting.
4. Expect patience and fewer rounds of follow-on. Some offices move slowly and invest once; others become long-term backers. Ask how they have handled follow-on rounds.
5. Do not ask them to lead a pre-seed unless they say they do. Very few family-office records list pre-seed (17 in our data). Bring them in alongside a lead, or at seed once you have traction.

Methods note

Data: Zalarma investor database, as of 2026-11-01. A family-office record is any US record whose investor type includes "family office"; it can be a firm record or a person who works at a family office. The comparison base is 33,282 US startup-investor records (angels, venture firms and partners, micro-VCs, family offices, corporate VCs and accelerators). One record can carry more than one type. State and metro come from each record's location; records without a location are left out of those tables. Stage, sector and check size are only what each record lists. Counts under 10 are suppressed, and we compute no shares from suppressed cells. These are records in our database, not a census of every family office in the US.
