Prime Impact Fund

Managing Directors Matthew Nordan, Johanna Wolfson, and Amy Duffuor jointly lead the investment team. Matthew Nordan, a long-time climate-tech investor, provides strategic direction. Johanna Wolfson brings a Ph.D. in physical chemistry and formerly led technology-to-market programs at the Department of Energy. Amy Duffuor adds renewable-energy project finance experience from Sunwealth. The day-to-day portfolio management is executed by Azolla Ventures, a related entity that shares key personnel.

Prime Impact Fund is an initiative of Prime Coalition, a 501(c)(3) nonprofit organization based in Cambridge, Massachusetts. Prime Coalition raises philanthropic and corporate capital to fund climate solutions that are too early or too technically risky for mainstream venture. The Prime Impact Fund portfolio itself is managed by Azolla Ventures, a separate investment firm. This structure separates charitable grantmaking from the equity portfolio while allowing Prime Coalition to anchor deals that Azolla subsequently executes.

The fund explicitly targets earliest-stage companies: pre-seed, seed, and start-up. It uses its catalytic capital structure to underwrite technical risk before commercial milestones are proven. Portfolio companies Lilac Solutions and Sublime Systems were backed while technology was still at bench or pilot scale. There is no indication the fund participates in growth equity or later-stage rounds.

The portfolio spans lithium extraction (Lilac Solutions), cement decarbonization (Sublime Systems), carbon removal (Charm Industrial, Verdox, Vesta), long-duration storage (Noon Energy), fusion (Avalanche Energy Design), industrial efficiency (Via Separations), and geothermal exploration (Zanskar). The fund screens every investment for gigaton-scale emissions reduction potential using proprietary techno-economic models alongside climate science.

All disclosed activity is direct venture investment into operating companies. There is no public record of fund-of-fund commitments, secondary purchases, or co-investment alongside outside general partners. The fund's thesis is built on proprietary sourcing of deep-tech startups, often from university laboratories and government research programs, rather than syndicate participation.

The firm states its investors are visionary families, foundations, and corporations, but no individual names have been publicly disclosed. The Prime Coalition parent accepts philanthropic donations, which can flow into the fund. This capital structure — mixing charitable grants with for-profit equity — is a deliberate design to de-risk early-stage climate ventures.

The fund does not publicly describe a co-investment program. Its website emphasizes the Prime Coalition initiative's role in bridging the gap left by traditional venture capital, suggesting the fund intends to lead or anchor rounds where conventional firms perceive excessive technology risk. Any syndication appears opportunistic rather than a core operating model.
