General Atlantic
General Atlantic is a New York growth-equity and private-equity firm, one of the world's largest, that invests in water only occasionally. Its single water bet is Allonnia, a synthetic-biology company whose foam-fractionation technology strips PFAS from contaminated water. As of 2025 it has backed one water company across four deals.

The take
General Atlantic is not a water fund, and that is the first thing a newcomer should understand. Founded in New York in 1980, it is one of the largest growth investors in the world, managing more than $100 billion across growth equity, credit, energy transition and sustainable infrastructure, with over 830 companies backed in its history. Water is a rounding error on that platform, which is exactly why its rare water bets are worth reading closely.
General Atlantic's water exposure runs through a single company: Allonnia, a Boston synthetic-biology business spun out of Ginkgo Bioworks in 2020 to attack waste and contamination with engineered microbes. The water angle is concrete: Allonnia's SAFF foam-fractionation system pulls PFAS, the so-called forever chemicals, out of contaminated water. General Atlantic has backed it across four rounds, most recently in late 2025, and the deal sits with its Life Sciences team, not a water desk.
General Atlantic treats water the way it treats most frontier categories: selectively, through the lens of a sector it already knows, and with a large cheque rather than scattered small bets. Brett Zbar, who runs its Life Sciences practice, leads General Atlantic's relationship with Allonnia, a biotechnology story that happens to clean water. Its wider climate effort, the BeyondNetZero fund and the Actis sustainable-infrastructure arm, gives General Atlantic more water-adjacent reach than its single tracked water deal suggests, but for now Allonnia is the whole of its water portfolio.

Frequently asked
- What does General Atlantic invest in?
- General Atlantic is a global growth-equity and private-equity firm that backs technology, financial services, healthcare, consumer and life-sciences companies worldwide. It also runs climate and infrastructure strategies. Within that broad mandate it makes only occasional water investments, the clearest being Allonnia, a synthetic-biology company that treats contaminated water.
- Is General Atlantic a water fund?
- No. General Atlantic is a generalist growth investor managing more than $100 billion, not a dedicated water fund. It appears in water coverage because of a single tracked water bet, Allonnia, whose technology removes PFAS from water. Specialist water funds invest across dozens of water companies; General Atlantic backs one.
- What water company has General Atlantic backed?
- General Atlantic has backed one water company in our database, Allonnia, across four funding rounds. Allonnia is a Boston synthetic-biology firm spun out of Ginkgo Bioworks in 2020. Its SAFF foam-fractionation system strips PFAS, known as forever chemicals, from contaminated water, and it also recovers critical minerals.
- Who runs General Atlantic?
- General Atlantic is led by Chairman and CEO Bill Ford, who joined in 1991 and has run the firm since 2007. Its only tracked water investment, Allonnia, sits with Brett Zbar, Managing Director and Global Head of Life Sciences, rather than a dedicated water or climate team.
- Where is General Atlantic based?
- General Atlantic is headquartered in New York City and invests globally, with offices across the Americas, Europe, Asia and the Middle East. Founded in 1980, it manages more than $100 billion across growth equity, credit, energy transition and sustainable infrastructure, including the occasional water-related company such as Allonnia.
