Key people at PRIME Coalition.
PRIME Coalition was founded in 2014 by Sarah Kearney (Founder & Executive Director).
Prime Coalition facilitates the deployment of philanthropic capital into nascent climate solutions. The organization leverages its expertise in philanthropy and evidence-based impact assessment to guide donors toward impactful programs focused on climate change mitigation, adaptation, and resilience, effectively removing hurdles for charitable investment in breakthrough technologies.
The coalition began its work in 2014, driven by the understanding that significant environmental challenges necessitate market-based solutions capable of rapid scaling. This insight led Prime and its early group of philanthropists to pioneer the use of catalytic capital alongside traditional grantmaking, specifically targeting the reduction of global greenhouse gas emissions through innovative early-stage technologies.
Its services cater to philanthropists looking to engage in climate finance, including many who are new to catalytic investing. Prime Coalition's overarching vision is to accelerate the advancement of untapped climate solutions, fostering both speed and scale in the collective effort to combat climate change and cultivate a more sustainable future.

Key people at PRIME Coalition.
Prime Coalition is a 501(c)(3) nonprofit organization founded in 2014 that mobilizes catalytic capital—philanthropic grants, recoverable grants, and program-related investments (PRIs)—to bridge funding gaps for high-impact climate tech companies facing commercialization risks.[3][7] Its mission centers on steering mission-aligned capital toward market-driven solutions that could mitigate gigaton-scale greenhouse gas emissions, particularly in sectors like clean energy, climate infrastructure, and transformative technologies.[1][4][7] Rather than traditional venture investing, Prime's philosophy emphasizes "additionality," deploying charitable funds into ventures unlikely to attract commercial capital otherwise, while fostering follow-on investments from impact-aligned managers.[2][3] Key programs include the Prime Impact Fund, Azolla Ventures (a $239 million blended fund launched in 2023), Trellis Climate for infrastructure scaling, and tools like the CRANE emissions assessment platform.[1][2][4] By 2025, Prime had channeled $76.5 million into its built funds and $21.8 million into facilitated ones, influencing the climate startup ecosystem by de-risking early-stage innovations and building evidence for catalytic models.[5]
Prime Coalition was founded in 2014 by Sarah Kearney in Cambridge, Massachusetts, to address the "valley of death" in clean energy tech commercialization—gaps between research grants and private investment, and between validation and deployment.[1][6] Kearney, recognizing that promising market-based climate solutions often stalled due to high risks and long timelines, positioned Prime as a financial intermediary to source, vet, and match these opportunities with philanthropic funders.[6] Early efforts focused on a "PRIME Investment Funnel" for screening enterprises and incubating the Aligned Intermediary with Stanford experts to engage large institutional investors like pensions and endowments.[1] By 2019, Prime pivoted to a portfolio approach with the $40 million Prime Impact Fund, blending catalytic capital to attract traditional investors.[6] Evolution continued with Azolla Ventures in 2023 and platform expansion in 2025 to include facilitated and curated funds, reflecting a shift from deal-by-deal matchmaking to scalable fund orchestration.[2][5]
Prime stands out in climate investing through its nonprofit structure and rigorous impact discipline:
Prime rides the urgent wave of climate tech scaling amid global net-zero pressures, where traditional VC shies from deep-tech risks despite trillion-dollar market needs.[6] Its timing aligns with rising philanthropic interest—U.S. foundations' 1% grant shift could rival global climate VC—and post-COP commitments for blended finance.[3] Favorable forces include policy tailwinds (e.g., IRA incentives), sovereign fund mobilization, and evidence gaps in impact measurement that Prime fills via CRANE and Frame.[1] By de-risking "valley of death" ventures in renewables, manufacturing, and infrastructure, Prime influences the ecosystem: it has spurred follow-on commercial capital, launched Azolla as a field experiment, and expanded platforms to orchestrate $100M+ by 2025, normalizing catalytic investing for pensions, family offices, and DAFS.[2][5][8]
Prime's trajectory points to scaled platform leadership, with quiet market testing of Prime-Curated funds in 2026 building on 2025 pilots, potentially channeling billions by aggregating more philanthropists into vetted climate vehicles.[5][7] Trends like AI-driven impact diligence, sovereign green funds, and gigaton infrastructure will amplify its role, especially as commercial capital chases de-risked winners. Its influence may evolve from niche intermediary to ecosystem orchestrator, recouping subsidies via fund partnerships while iterating on additionality proofs—positioning Prime as the essential waterway for catalytic capital in a $2T+ climate economy.[2][4] This cements its decade-long mission: unlocking untapped solutions at speed and scale.[7]
