Boston Family Office List

This list covers 30 family offices based in Boston. It includes 18 single-family offices and 12 multi-family offices, so readers can compare organizations serving one family with firms that work across multiple families. Disclosed focus areas include private equity and venture capital, alongside technology, real estate, alternative investments, hedge funds, fintech and artificial intelligence. The range of investment interests may help founders, fund managers and advisers identify profiles worth researching against a particular mandate. Public profiles also vary in depth: 11 offices disclose assets under management, while founding dates span a broad range. Use the table as a starting point for checking fit, not as evidence that an office is actively investing or accepts unsolicited proposals. Before reaching out, review each office’s stated focus and tailor a concise note to its investment approach.

Questions about this list

What kinds of family offices are included?

The list includes 18 single-family offices and 12 multi-family offices identified with Boston as their listed city. It does not add nearby offices. These categories describe the office structure, but do not by themselves indicate investment capacity, mandate or willingness to consider an approach.

Which investment interests appear most often?

Private equity is listed for 11 offices and venture capital for 10. Other recorded focus areas include technology, real estate, alternative investments, hedge funds, fintech and artificial intelligence. A focus label is a useful research clue, though it does not confirm a current mandate or a fit with a specific opportunity.

How should I approach a Boston family office?

Start by checking the office’s public profile and stated investment focus. Send a concise, relevant note that explains the opportunity, why it may fit that focus and what information is available for review. Avoid assuming that a family office accepts unsolicited proposals, and follow any published submission guidance.

Does the table show assets under management?

Assets under management are disclosed for 11 of the 30 listed offices. The field is shown where available, while the remaining profiles may not publish it. Treat disclosed figures as profile information rather than a complete comparison of resources or an indication of funds available for a particular investment.

What does the full list add?

The full list adds contact data, decision makers and check size fields to support more targeted research. Those fields can help founders, fund managers, investors and advisers assess whom to contact and whether a potential range may fit. A request provides information for research, not an introduction or investment outcome.
