Investment thesis
CTV backs category-defining startups on a path to venture-scale returns that can advance the energy industry and unlock unique commercial value through an investment from Constellation. Its focus spans large, interconnected markets: power and renewables (both hardware and software across the power sector), electrification and EV technologies enabling the transition to net-zero emissions across commercial, industrial and residential segments, emissions management (removal, monitoring, verification, and attribute tracking and trading), and digital strategies driven by digitalization trends in the energy sector. CTV collaborates with Constellation's operating businesses and customers to help portfolio companies grow, offering support beyond capital, including follow-on raises and commercial introductions.
