TerraBlue
Novel electrochemical direct air carbon capture technology achieving costs below $150/ton. Targeting commercial deployment of systems capable of removing 1 million tons of CO2 annually by 2028. Backed by leading climate tech strategics.
Why We Invested
TerraBlue's founding team — ex-MIT electrochemistry researchers — had a genuine materials science breakthrough that dropped DAC energy consumption by 38% vs. leading incumbent processes. With three utility patents filed and a credible cost roadmap to sub-$100/ton, this was the most technically differentiated carbon removal bet we had seen.
Post-Investment Outcomes
Raised $28M Series A led by Breakthrough Energy Ventures (Q3 2025). First commercial 10,000-ton/year pilot facility operational in West Texas. Cost per ton certified at $142 — 6 months ahead of schedule. Contracted offtake agreements signed with two Fortune 100 companies totaling $45M over 5 years.
SolarGrid
Community solar platform enabling renters and low-income households to access clean energy without rooftop installation. Serving 45,000+ households across 18 states with an average 28% reduction in energy bills. Strong regulatory tailwinds.
Why We Invested
The founder's background building community energy programs at NRDC gave SolarGrid an immediate distribution advantage through 200+ community organizations across low-income markets. The IRA's direct-pay provision for community solar made the unit economics structurally sound for the first time, and SolarGrid was the most operationally sophisticated platform we had evaluated.
Post-Investment Outcomes
Grew from 8,000 to 45,000+ subscriber households in 14 months. Raised $20M Series A co-led by Energy Impact Partners and Generate Capital (Q1 2025). Expanded to 18 states. Average subscriber saves $420/year on energy bills. Partnership with HUD to reach public housing residents across 6 metro areas announced February 2025.
ClimateAI
Enterprise climate risk modeling platform used by banks, insurers, and real estate firms to quantify and price physical climate risk in their portfolios. Partnering with three of the top ten global banks. Revenue growing 3x year-over-year.
Why We Invested
The SEC's climate disclosure rules and ISSB standards were creating a compliance-driven market that barely existed the year before. ClimateAI's proprietary ensemble modeling approach — combining satellite imagery, hydrological models, and insurance loss data — produced physical risk projections 40% more accurate than incumbent catastrophe modeling firms. The enterprise sales pipeline was already $8M at seed close.
Post-Investment Outcomes
ARR grew 3x in 12 months to $4.2M. Now partnering with 3 of the top 10 global banks and 2 of the top 5 global insurers for portfolio-level physical risk assessment. Raised $24M Series A led by Obvious Ventures and Climate Capital in October 2024. Recognized as a Forrester Emerging Vendor in climate risk analytics, Q4 2024.
