Founders seeking Prime Coalition funding should know this is not a venture fund in the usual sense. Prime Coalition is a nonprofit public charity — a US 501(c)(3) founded in 2014 — whose mission is to steer and influence capital towards scalable climate solutions by unlocking catalytic capital: charitable, impact-first investment into solutions that commercial capital cannot yet fund. The results it reports are striking: US$108MM of catalytic capital into Prime has crowded in US$2.8bn of external capital, supporting 58 companies.

Investment thesis

The mission statement: "We empower philanthropists to advance untapped climate solutions with speed and scale." Prime works through two strategies — steering capital (deploying charitable investment capital into early-stage climate ventures) and influencing capital (open tools and investor networks that improve climate investment practice). Impact and additionality are assessed on evidence, with speed and scale achieved by crowding in commercial capital behind the catalytic first cheque. Prime's own operating budget and AUM are not publicly disclosed.

Sectors, stages and cheque size

Sectors span climate tech broadly: energy, industrial processes, carbon capture and storage, shipping, battery recycling, buildings, EVs and forestry carbon. Stages cover early-stage ventures through Azolla Ventures and first-of-a-kind project deployment through Trellis Climate. Prime is not itself a fund manager, but the vehicles it launched carry real numbers: Azolla Fund I is a US$239 million blended fund (launched by Azolla Ventures, which Prime spun out in 2021), and the Prime Impact Fund was a US$50 million catalytic vehicle that made its 16th and final investment in 2021.

Notable portfolio and leadership

Via Azolla Ventures, the portfolio includes Heaten (high-temperature heat pumps for industrial processes), Funga (forest microbiome optimisation for carbon storage), SiTration (membranes for low-cost battery recycling), Carbon Reform (carbon capture systems in buildings), Calcarea (decarbonising shipping) and Scalvy (modular electric vehicle drivetrains). Sarah Kearney is Executive Director, named in Prime's press releases.

Programmes run by the firm

Prime's platform is its programme set: Azolla Ventures (early-stage impact-first climate VC, spun out 2021), the Prime Impact Fund (US$50m catalytic vehicle, completed), Trellis Climate (catalytic capital for first-of-a-kind climate projects), Project Frame (a nonprofit investor community of 340 investment firms representing US$471.8bn in VC/PE AUM as of January 2024, building forward-looking emissions impact methodology), CRANE (an open-access tool, built with Rho Impact, for assessing the forward-looking emissions impact of investments), and the Catalytic Capital Intermediation Resources Library for field-building. Prime's knowledge-sharing resources count 19,250 users, and 100+ philanthropists have made their first catalytic investment through the platform.

How to get funding from Prime Coalition

There is no public founder pitch or application page on primecoalition.org — capital is deployed through Azolla Ventures and philanthropist partners, and the site offers newsletter signup and "Join Us" partner outreach. Climate founders should engage Azolla Ventures directly for early-stage cheques, and note that Prime's tools (CRANE, Project Frame) are open resources worth using regardless.

Why it matters for founders

If you are building a climate solution that commercial VCs call "too early", Prime Coalition exists precisely for you: US$108MM in catalytic capital, US$2.8bn crowded in behind it, and the US$239 million Azolla Fund I writing early-stage cheques. The route in is Azolla Ventures — and the open tools like CRANE can strengthen any climate pitch.
