Impact funds, foundations, ESG-focused LPs
Data rooms for impact and ESG investors
Impact investors ask two questions: will this return money, and will it deliver the outcome it promises? The room needs evidence for both.
Impact diligence adds a theory of change, outcome metrics, measurement methods and any third-party verification. ESG-focused LPs also review policies, emissions data and governance.
After investing, impact investors report on outcomes, so the room continues with periodic impact data next to financial reporting.
What matters most: Evidence and reporting over time; a room that holds versioned impact data next to financials.
