About BOLDR

Boldr is a UK energy-management company that connects residential HVAC and other home energy equipment through HVAC contractors so homes can manage demand and provide flexible capacity to the grid. Rather than selling only to consumers, Boldr supplies contractors with smart thermostats, connected controls and software for servicing and lifetime customer relationships, with distribution partnerships including Source 1 (Bosch) and Daikin in North America. Funding includes a $3.2 million seed in 2025 and a $5 million pre-Series A in August 2026 led by Unconventional Ventures with Ada Ventures, Inclimo, Techstars, S20, Prosegur and others to expand into central HVAC and grow the US contractor network.
