NorthX Climate Tech is an independent Canadian nonprofit investor and commercialization catalyst for climate hard tech. Founded in October 2021 as the BC Centre for Innovation and Clean Energy (CICE), it launched with $105 million in commitments from the Government of British Columbia, Shell Canada, and the Government of Canada through Natural Resources Canada’s Energy Innovation Program. NorthX is based at Suite 1210, 1066 West Hastings Street in Vancouver and is led by President and CEO Sarah Goodman. NorthX backs physical technologies that can reduce or remove greenhouse gas emissions while producing economic benefits for British Columbia and Canada. Its focus includes energy storage and grid capacity, industrial decarbonization, clean fuels, wildfire prevention and response, carbon management, climate adaptation, and other hardware- and materials-led solutions. The organization targets the commercialization gap between technical promise and market deployment, especially projects at technology readiness levels 4–9. Funding is non-dilutive and tailored by opportunity: NorthX says investments may be repayable or non-repayable, with approved Open Intake projects receiving milestone-based reimbursement funding. Support extends beyond capital to technical validation, lifecycle assessment, investor and industry introductions, market readiness, and follow-on funding. NorthX reports that, by May 2026, it had backed more than 74 projects with over $57 million and helped catalyze more than $600 million in follow-on investment. Those figures are reported by NorthX and are not presented as independently audited outcomes. The Women in Climate Tech initiative adds a gender-lens pathway for capital-intensive climate ventures. In September 2026, NorthX reported that more than $36 million had been committed across 45 projects at companies with women in leadership—over 58% of its total capital commitments—and that those investments had unlocked more than $430 million in additional capital.

Prime Coalition is a Cambridge, Massachusetts nonprofit that helps philanthropists deploy catalytic capital into climate solutions that conventional investors often skip. Since 2014, Prime has focused on additionality: filling gaps where technology risk, long timelines, or first-of-a-kind infrastructure make ordinary venture or project finance a poor fit. The organization stewards impact-first programs rather than acting as a classic closed-end VC. That includes earlier vehicles such as Prime Impact Fund and Azolla Fund I (managed with Azolla Ventures), plus Trellis Climate for first-of-a-kind climate infrastructure projects that need risk-tolerant capital to reach commercial scale. Public materials cite on the order of $108M in catalytic capital into Prime programs and about $2.8B in external capital crowded in, with dozens of companies supported through impact-first funds. Prime's role in the ecosystem is bridge and standard-setter. It evaluates impact and additionality, helps philanthropists make their first catalytic investments, and publishes tools and field-building resources (including work around Project Frame). For founders, Prime is less a cold outbound check source and more a signal that your solution needs catalytic capital and can prove climate impact that markets alone will not fund yet. If you are building a breakthrough climate company or FOAK project that stalls in the valley between philanthropy and commercial capital, Prime is the kind of steward that exists to close that gap.

Prosper Global Ventures is the early-stage impact investing and venture-building platform of Prosper Global, the global development organization formerly known as Mercy Corps.

Earlier Fund I activity also included Southeast Asia. Prosper Global’s current Ventures page reports 61 early-stage companies supported, $753 million in follow-on capital catalyzed, and 46.3 million customers reached across 90 countries. Its 2025 impact report says 83% of portfolio companies had raised follow-on capital and 46% had at least one woman co-founder. These are Prosper Global Ventures’ reported portfolio figures, not independent impact measurements.

Representative investments made under the Mercy Corps Ventures name include Pula, which provides agricultural insurance and advisory products for smallholder farmers; Floodbase, which develops flood-risk data and analysis; Wasoko, a last-mile commerce and financing platform for small retailers; AgriAku, an agricultural input marketplace; Ejara, an inclusive savings and investment platform; and Verqor, an agri-fintech platform serving farmers in Mexico. Prosper Global Ventures is embedded within Prosper Global’s humanitarian and development network, giving portfolio companies potential pathways to test products with communities affected by climate volatility, financial exclusion, fragile food systems, and infrastructure gaps. The venture platform is associated with Scott Onder, its co-founder and senior investment leader, while Tjada D’Oyen McKenna leads the parent organization as CEO.
