Patient capital, deployed on conviction

Sustainable Impact was founded by a two-decade veteran of sustainable investing, backed by a single-family office with a fifty-year history. That heritage gives us a long horizon and the latitude to shape each investment around the company it serves, not a fund timetable.

What we bring

How we back founders

We fund companies at every stage, from seed and Series A through to pre-IPO and buyout. Our single-investor structure keeps friction low, letting us move quickly, tailor terms and run the deal process end to end.

Guided by a board of renowned sustainability experts, we bring strategic and operational support, helping early-stage companies scale while turning impact into everyday practice.

We open our ecosystem to every portfolio company: introductions to customers, to strategic partners, and to the later-stage investors, including sovereign wealth and major venture funds, that carry a company forward.

A different kind of impact investor

A venture fund lives on a roughly ten-year clock: it must return capital whether or not a company has matured, and often sells its winners before their potential is fully realised. Our capital carries no such clock, so it can stay invested through the later years, where much of a venture return is ultimately made.

Source and method. This chart is illustrative. It plots the growth of a single hypothetical dollar compounding at 15% a year. The 15% figure is the pooled net annualised return (internal rate of return) of the Cambridge Associates LLC US Venture Capital Index over the 25-year period ending 30 June 2020, stated net of fees, expenses and carried interest. The two values marked on the curve are the arithmetic result of applying that rate, not separately observed data points: 4.0× is 1.15 to the power of 10 (a ten-year hold) and 8.1× is 1.15 to the power of 15 (a fifteen-year hold), each rounded to one decimal place. An internal rate of return is not the same measure as a constant annual compounding rate, so the curve is a simplified illustration of how a longer holding period can affect an outcome, not an exact model of venture capital returns. Past performance is not a guide to, and is no guarantee of, future results. This exhibit is provided for information and context only. It is not investment advice, not an offer or a solicitation to invest, not a forecast or projection, and not a representation of the past or expected returns of Sustainable Impact, any fund or vehicle it manages, or any investment. Index figures do not represent the return of any actual portfolio, and an index cannot be invested in directly. Cambridge Associates is the source of the underlying index data and is referenced for identification and attribution only.

How do we define a good investment?

We weigh three variables

01

Risk

We take on meaningful risk, especially at the earliest stages, where our capital and expertise create the most value. Our independence lets us size each position to the opportunity, not to a mandate.

02

Return

We target an IRR of 25%1 and a 10x multiple2, concentrating capital in a small group of exceptional companies.

03

Impact

Every investment must advance at least one UN Sustainable Development Goal and do no significant harm to the others, against the OECD and UN safeguards. Impact is not a constraint on returns; it is a third dimension we underwrite alongside them.

Note: all figures shown are forward-looking targets and objectives, not guarantees or projections of future results. Actual results may differ materially.

  1. Target internal rate of return (IRR) over the life of the vehicle; an objective only, not a forecast or guarantee of returns.
  2. Target gross multiple of invested capital over the life of the vehicle; an illustrative objective, not a projection.
  3. Target aggregate capital to be deployed over the vehicle's investment period; subject to change.
  4. Target annual CO₂ sequestration across portfolio companies at maturity, based on internal estimates and methodology; subject to revision.
