Prime Impact Fund Research
Investment Thesis
Prime Impact Fund invests in transformative technology companies with the potential for gigaton-scale climate impact. Founded in 2018 and governed by Prime Coalition, a 501(c)(3) nonprofit organization, Prime Impact Fund represents a unique venture capital model that prioritizes climate impact over financial returns. The fund is structured as 100% catalytic capital—philanthropic investment that accepts disproportionate risk and concessionary returns to address critical capital gaps in early-stage climate technology.
The fund's core belief is that breakthrough climate solutions come from ambitious entrepreneurs tackling hard-tech challenges. Prime Impact Fund focuses on companies that can reduce greenhouse gas emissions at gigaton scale, requiring both technological breakthrough and commercial viability. The fund emphasizes "diamonds in the rough"—startups that can grow into historically significant, planetarily impactful companies forming the foundation of a low-carbon economy.
Investment Stage and Check Size
Prime Impact Fund is an early-stage venture capital fund with the following investment parameters:
Stage Focus: Seed and Series A investments, with selective pre-seed participation for exceptional technical founders. The fund targets companies with early traction, proof-of-concept validation, and clear paths to addressing significant climate challenges.
Check Size: Typical investments range from $1 million to $4 million. The fund's modest check sizes reflect its focus on early-stage climate technology ventures that require patient, mission-aligned capital rather than the scale-focused checks of traditional venture investors.
Capital Availability: With $50 million deployed since 2020 (Fund I closed with $52 million), Prime Impact Fund has maintained a deliberate, quality-focused investment pace focusing on deep technical diligence and impact assessment.
Lead Tendency and Decision Process
Prime Impact Fund primarily leads or co-leads investment rounds, positioning itself as a committed capital partner rather than a passive follow-on investor. The fund's leadership structure enables partnership-based decision making:
- Three Co-Managing Directors (Matthew Nordan, Dr. Johanna Wolfson, Amy Duffuor) with complementary expertise in venture capital, clean technology, and impact investing
- Board seat participation on portfolio companies
- Active management involvement focused on scaling impact alongside business growth
- Long-term holding periods and patient capital approach typical of catalytic investment vehicles
Recent Investment Activity
Prime Impact Fund has demonstrated consistent deployment and strong conviction in its portfolio:

- Companies addressing fundamental scientific and engineering challenges
- Solutions with clear paths to gigaton-scale impact
- Teams aligned with long-term impact goals beyond financial returns
The fund explicitly evaluates "techno-economics and climate impact with equal, fact-based rigor," meaning companies must be both technically viable and commercially sustainable.
Geographic and Market Focus
Primary Geographic Focus: United States, with particular concentration in climate technology hubs (Cambridge/Boston area as headquarters, San Francisco Bay Area, and other innovation centers).
Global Perspective: While US-focused, the fund recognizes that climate solutions require global deployment and serves entrepreneurs and technologies with global impact potential.
