Family Angel Management Fund

Brock Mansfield, Managing Partner, leads all investment activity. His background spans Endeavour Capital and over 20 years of early-stage technology deals. The firm currently lists no other investment professionals publicly, indicating a concentrated decision-making structure.

Deal flow originates primarily through Mansfield's deep Seattle network. He is co-founder and Chairman of Envest, a Seattle angel network, and a past president of EO Seattle and the Stanford GSB Alumni Association. This community-driven model prioritizes local operator and founder relationships.

The firm invests directly in early-stage companies. Publicly reported activity shows co-investment alongside Seattle and San Francisco seed funds, but no fund-of-fund commitments. The firm invests its own vehicles' capital directly into portfolio companies.

FAMFund targets early-stage, seed, and venture rounds. Portfolio entries range from stealth-stage rounds (Hilos) to seed rounds (JetClosing, Integris) through later follow-on rounds supported by major venture firms like SoftBank. The strategy is stage-agnostic within early venture.

The firm does not publish an explicit exclusion list. Public portfolio composition suggests active avoidance of sectors requiring heavy regulatory navigation, deep science timelines, and non-technology manufacturing, with concentration instead on software, consumer platforms, and digital health.

No. The firm operates as an asset manager / private equity structure running pooled investment vehicles (Fund I and Fund II). While centered on a single managing partner, it functions as a private investment firm rather than a traditional family office.

Mansfield's civic engagement runs through separate volunteer and board roles. He is co-founder of Seattleworks and has served on boards for Lakeside School and the Mercer Island Boys & Girls Club. These operate distinctly from FAMFund's investment vehicles, with no evidence of a dedicated philanthropic foundation under the FAMFund umbrella.
