## Questions

### What is Truestone Impact Investment Management's investment mandate?

The firm pursues a private equity strategy that explicitly targets measurable social and environmental impact alongside competitive financial returns. Truestone deploys capital into direct investments where it can exercise active ownership to embed impact and governance improvements. The mandate spans early-stage ventures through to growth equity.

### Does Truestone operate as a traditional private equity firm or is it structured differently?

Truestone is structured as a specialist impact investment manager rather than a conventional private equity firm. Its investment process applies dual diligence — evaluating both financial return potential and impact additionality. This means portfolio construction and committee decisions weigh impact metrics alongside standard financial underwriting.

### Where does Truestone deploy capital geographically?

While headquartered in London, Truestone evaluates opportunities internationally, with historical focus on Sub-Saharan Africa, South Asia, and parts of Europe. The firm targets markets where private capital can address structural gaps, and where operating presence can directly influence company-level outcomes.

### Does Truestone manage separate vehicles for different impact themes or stages?

Details of Truestone's fund structure have not been widely disclosed. The firm covers a range of investment stages — early, expansion, and late-stage growth — but whether these sit within a single vehicle or multiple dedicated funds is not publicly documented.
