TOBY MITCHENALL'S IMPACT INVESTING ANALYSIS
IMPACT 75: 2026
METHODOLOGY
PEI Group’s GP lists and rankings are based on the amount of capital raised for private markets funds that held a final close between 1 January 2021 and 31 December 2025, as well as capital raised for funds that were actively fundraising at the end of the counting period.
For the purpose of these lists, we only count closed-end funds for which the fund manager has full discretion over the investment process, from selection over management to exit. As a consequence, we only accept blind-pool funds in which LPs cannot exercise investment decisions and have no liquidity options before the end of the (multiple years long but finite) fund life, without approval from the GP. Funds must invest solely into private assets and GP commitments (for interest alignment only) can be included, too. Capital committed by affiliated entities as well as fund leverage is not eligible. Finally, we do not count fund of funds as well as recycled or rolled-over capital from previous fundraises.

Impact capital: For this ranking, we use GIIN’s definition of impact, namely: “Impact investments are investments made with the intention to generate positive, measurable social and environmental impact alongside a financial return in private markets. Impact investments can be made in both emerging and developed markets, and target a range of returns from below market to market rate, depending on investors’ strategic goals.
“The impact investment market provides capital to address the world’s most pressing challenges in sectors such as renewable energy, sustainable agriculture, affordable/social housing, as well as debt and equity investments in firms that focus on providing answers to such challenges.”
For funds in market, capital raised via actual LP commitments which were made before the end of the counting period can be included, too. We cannot include commitments made after the end of the counting period nor do we accept targets or expected commitments. For open-end funds that launched prior to the beginning of the counting period, we only count capital raised entirely within the five-year counting period.
The Impact 75 is not a performance ranking, nor does it constitute investment recommendations.
