What Treebeard Trust does

Treebeard Trust is a UK-registered charitable foundation (Charity Number 1200102) established in 2011 by Barnaby Wiener. It deploys capital through two complementary vehicles: grant funding and impact investments. The foundation operates across four thematic areas — Sustainable Planet, Vulnerable Communities, Justice, and Systems Change — and serves mission-driven organisations and grassroots initiatives primarily in the UK and East Africa, with a growing Sub-Saharan Africa presence delivered through a long-term partnership with Egmont Trust dating to 2013.

The foundation's products span two tiers. On the grants side, strategic partnerships receive £50,000 or more per year, while innovation grants range from £20,000 to £30,000. On the impact-investing side, initial deployable capital starts at £50,000 (cumulative up to £250,000) across equity, debt, and property vehicles, with debt instruments typically running five or more years. The portfolio includes dozens of organisations. Approximately 35% of the endowment is currently allocated to impact investments, with a stated target of reaching 50%. The foundation does not accept speculative applications; investees are sourced through trusted networks.

The operating model is intentionally lean: one part-time staff member, a five-trustee board (Barnaby Wiener, Cassandra Wiener, Elisabeth Barrett, Mike Mompi, Andrew Purvis), and Director Shishir Malhotra (joined 2020). Annual grant deployment is less than £1 million. The foundation is a signatory to the Funder Commitment on Climate Change (2020) and pivoted its strategy in 2019 from individual outcomes to systems change, reflecting an evolution toward addressing root causes rather than downstream symptoms.
