Family Office Database

Single vs Multi Family Office

The label "family office" covers two structures that behave very differently when you are raising a fund. A single family office (SFO) exists to serve one family. It answers to that family, invests off a mandate the principals set, and almost never advertises. Many of the 3,409 SFOs in this database are effectively private. You learn they exist through filings, a portfolio company, or a shared connection, not a website. That opacity is exactly why a maintained database is worth having: the hard part is knowing the office is there at all.

A multi family office (MFO) pools the infrastructure of several families. It looks and operates more like a boutique investment firm, often registers with the SEC as an RIA, and is generally reachable through a named investment team. The 3,859 MFOs here are usually the faster path to a first meeting, though a single MFO may write on behalf of many underlying families, each with a distinct appetite. Knowing which structure you are approaching changes how you pitch: an SFO wants alignment with one family's long-horizon goals, while an MFO is screening on behalf of clients and cares about repeatability and reporting.

How to Find Family Offices for Your Fund

Finding family offices is a sourcing problem before it is an outreach problem. Because SFOs rarely market, the usual playbook is slow: mine SEC Form ADV and Form D filings for names, read the wealth press, work backward from a portfolio company's cap table, and lean on warm introductions. It works, but it takes months and it misses the offices that never surface in the outlets you happen to read.

A structured database compresses that. The practical sequence most emerging managers follow: filter to the family office type and geography that fit your fund, narrow by AUM so you are talking to offices that can write a check your size, read each profile to confirm the mandate overlaps your thesis, then reach the specific person who handles fund commitments. The goal is a short, qualified list — thirty offices worth a real conversation beat three hundred generic sends.

If you are raising a first or second fund, start narrow. Family offices are among the most receptive LPs to emerging managers precisely because they can move without an investment committee and take a longer view, but they still expect you to have done the homework of knowing why their office in particular fits.

Where the Data Comes From

Each record is assembled from public and regulatory sources, not scraped guesses. Multi family offices and their affiliated RIAs surface through SEC Form ADV registrations; funds actively raising appear in SEC Form D filings; family foundations tied to an office show up in IRS Form 990 returns. Those signals are cross-referenced with firm websites, press disclosures, and direct research before a record is published, and contact data is reverified on a rolling basis. The full methodology covers sourcing, verification cadence, and how accuracy is measured.

Free Alternatives, Honestly

You do not have to pay to start. Open, crowd-sourced lists like OpenVC, public Google Sheets that circulate among founders, and patient LinkedIn searching will all turn up family office names for free. They are a reasonable first pass. What they will not do is stay current, carry AUM or verified decision-maker contacts, or cover the private single family offices that make up most of the market — those lists skew toward the offices that are already easy to find. LPbacked keeps the browsing layer free (counts, profiles, locations) and charges only when you need verified contacts and filtering at scale, with a 7-day trial so you can test the data against your own list before paying.
