Treehouse Investments
Treehouse Investments was founded in 2013 by the Bangasser family. The family’s wealth originated in Seattle real estate holdings dating to the 1940s. The firm operates as a minority-owned single-family office that deploys capital at market rates while pursuing measurable environmental outcomes. The strategy centers on direct co-investments and SPVs in infrastructure assets. Focus areas include energy, water, and waste systems. Investments span Seed through Series B stages. Geographic reach covers North America, Europe, Asia, and Africa. Confirmed technology emphases include consumer tech, enterprise software, and ESG-related solutions. The firm also maintains a philanthropic component through mission-related investing. No AUM figure has been disclosed. Team size and additional offices remain unreported. The firm runs the Treehouse Climate Action Poem Prize, established in 2019 and administered with the Academy of American Poets. Treehouse Investments maintains a hybrid structure that combines permanent family capital with explicit tracking of non-financial KPIs alongside financial returns. This architecture separates the office from pure venture or traditional infrastructure managers while embedding sustainability metrics into every investment decision.
