Boldr develops a software and hardware platform—including smart thermostats and connected controls—that gives HVAC contractors visibility and control over installed residential heating and cooling equipment. The company partners with contractors and supply houses (including Bosch-owned Source 1 and Daikin) to deploy and service controls rather than selling directly to homeowners. Its platform is designed to coordinate HVAC systems and eventually batteries, EV chargers and solar to provide flexible capacity to the power grid during periods of high demand. Boldr is initially focused on residential and light commercial HVAC, with plans to expand into central HVAC systems and additional distributed energy assets. The company has raised an oversubscribed $3.2M seed round and a $5M pre-Series A to fund product development and North American distribution expansion.
