London Startup Boldr Secures $3.2M To Power Homes And Support The Grid

The platform helps homeowners cut costs while supporting grid operators amid rising electricity demand.

The funding round saw participation from North American and European venture funds, including Ada Ventures, Unconventional Ventures, Inclimo Climate Tech Fund, Prosegur, Techstars, S20 Fund, and Viva Holdings—the latter also a Boldr customer. Boldr is backed by industry veterans, including the former Head of Manufacturing at Tesla and the former Head of Engineering at SpaceX.

With electrification of heating, cooling, EVs, AI and data centers driving power demand, the US grid faces pressure. Wind and solar generation often occurs outside peak times, complicating grid management, while large-scale projects like nuclear or utility-scale renewables are slow and costly. Boldr offers a practical, household-level solution.

Boldr’s smart heating and cooling products, paired with a companion app, automate climate control, enable grid-connected savings, and help households manage energy bills in real time. By leveraging existing HVAC systems alongside EVs, home batteries and rooftop solar, Boldr unlocks distributed, flexible capacity quickly and cost-effectively.

Delivered through contractor networks, Boldr’s hardware and software integrate seamlessly into homes, allowing users to optimise consumption, reduce bills, shift usage away from peak hours, and supply energy back to the grid when needed.

Madi Abylyazov, Boldr’s CEO and co-founder, said the company views each home as a potential power plant:

By tapping into everyday energy devices, starting with HVAC, we can provide peak capacity to the grid while helping families lower bills and optimise usage. This round fuels our expansion across the US HVAC market and beyond.

The funding will speed up Boldr’s mission to turn homes into active grid resources, cutting costs for homeowners while supporting grid operators in managing rising demand. The company plans to expand partnerships with HVAC contractors and wholesalers, integrate more high-load household devices, and scale its residential energy platform to enhance grid flexibility.
