Seattle Single Family Offices List

This list covers five single family offices based in Seattle. Their recorded interests span real estate, technology, financial services, science park operation, commercial real estate development, industrial real estate, emerging education and energy. Each of those focus areas appears once, so the entries reflect a varied set of stated interests rather than a concentration in one sector. Public records show assets under management for two offices. The listed offices were founded between 2007 and 2015, with one founded after 2010. Founders and business owners can use these profiles to identify potential investment fit, while fund managers and research teams can compare the office focus areas and available firm details. Treat the stated interests as starting points for further diligence. A relevant sector alone does not establish that an office is actively investing, accepts outside approaches or fits a particular deal.

Questions about this list

What kinds of interests appear in the Seattle list?

The recorded interests include real estate, technology, financial services, science park operation, commercial and industrial real estate, emerging education and energy. Each focus area appears once in the profiles on this page. Use these categories to screen for possible relevance, then check an office's mandate and current activity before approaching.

Are all offices in this page single family offices?

Yes. The listed page statistics classify all five listed offices as single family offices, with no multi family offices recorded. That classification describes the database entries and does not by itself indicate how each office is structured or whether it invests external capital.

How much financial information is available?

Assets under management are disclosed for two of the five offices. The other entries do not have disclosed AUM in these page statistics. AUM is only one data point and does not establish available capital, preferred investment size or current willingness to invest.

How should I approach a Seattle family office?

Start with a concise explanation of the opportunity and why it may match the office's recorded interests. State the amount sought, intended use of funds, timing and relevant track record, then ask whether the office reviews opportunities like yours. Confirm fit before sending extensive materials, and avoid assuming that a listed focus means the office is actively investing.

What does the full list add?

The full list adds contact data, decision makers and check size fields to the public firm-level information shown here. Those details can help a researcher identify an appropriate person and assess potential fit before making a focused approach. Request the full list through the form to review the available fields.
