The listed offices are based across several markets, with 13 in the United States, 2 in Australia, 2 in the United Kingdom and 1 in Sweden.

Questions about this list

What kind of offices are included in this CIO list?

The page contains 22 single-family office profiles associated with CIOs. It summarizes firm-level information such as locations and investment focus areas where those fields are available. A CIO-related profile can be a useful starting point for investment research, but it does not establish the person’s scope of authority or whether the office is reviewing opportunities.

Which locations are most represented?

The United States accounts for 13 offices, while Australia and the United Kingdom account for 2 each and Sweden for 1. London and New York are the most represented cities, with 2 offices apiece. These figures describe the locations in the list and are not a measure of investment activity in those markets.

What strategies and sectors appear in the profiles?

Hedge funds, private equity and real estate each appear for 6 offices. Alternative investments and venture capital each appear for 5. Software and healthtech are also listed for 3 offices each, and fund-of-funds for 2. Focus tags indicate stated areas of interest, not a commitment to a particular transaction.

How should I approach a family office CIO?

Research the office’s profile first and explain the connection between its stated focus and your opportunity. Make the strategy, stage, capital sought and potential fit easy to assess, and keep the first message direct. A CIO title may not cover every investment decision, so confirm the right decision process before relying on the title alone.

What extra information is in the full list?

The full list adds contact data, decision makers and check size fields. These details can support more focused prospect research and help you prepare relevant outreach. They do not guarantee a response, an introduction, funding or an investment decision.
