Vireo Ventures is an early-stage venture capital firm focused on climate tech, energy transition, and sustainability-driven software and infrastructure, typically investing at seed and early Series A. The firm looks for founders building commercially viable solutions that address emissions reduction, energy efficiency, or climate resilience with clear deployment paths. Vireo Ventures is most relevant for founders with climate-native business models and early traction, and is not suitable for general SaaS or consumer startups without a material climate impact thesis.
