Aina Ventures

ClimateAI Ventures (legal entity Aina Climate AI Ventures) is an early-stage venture capital firm and startup studio based in Redwood City, California, that backs companies using artificial intelligence to deliver climate impact across sectors such as climate technology, energy, and grid infrastructure. The firm invests at the pre-seed, seed, and seed-extension stages, primarily in U.S.-based founders. Its debut vehicle, Aina Climate AI Ventures I, filed its initial SEC Form D in October 2024 and remains open; reported limited partners include ImpactAssets and National Grid Partners. Specific check sizes and the total fund size are not publicly disclosed. Founders building AI-native climate solutions at the earliest stages are the strongest fit; those seeking later-stage growth capital, hardware-heavy projects outside the firm's AI thesis, or investment outside the U.S. are likely less suited.
