Investment thesis
CTV invests in category-defining companies advancing the energy industry, targeting large, interconnected markets across the power sector. Its focus areas include power and renewables (both hardware and software), electrification technologies enabling net-zero emissions across commercial, industrial, and residential segments, emissions management (removal, monitoring, verification, and attribute tracking/trading), and digital strategies driving digitalization of the energy sector. CTV prefers companies from post-lab-bench through growth stages, writing checks of $2M-$10M, and leads roughly one in four of its investments. It seeks startups on a path to venture-scale returns where its backing can unlock unique commercial value, collaborating with Constellation's operating businesses and customers to drive mutual growth.
