Boldr Raises €4.2M for Smart HVAC and Grid Flexibility

Boldr, a London-based innovator in smart building energy management, has successfully closed a €4.2 million pre-Series A funding round. This capital infusion is earmarked for expanding its reach into North American markets, enhancing its software solutions for contractors, and broadening its smart climate control capabilities across diverse residential and commercial heating and cooling systems.

The investment was spearheaded by Unconventional Ventures, with significant backing from Ada Ventures, Tetrad Ventures, Davidovs Venture Collective, Roxbury Asset Management, the Inclimo Climate Tech Fund, Prosegur, Techstars, the S20 Fund, and PropelX. This latest funding follows a robust €2.7 million Seed round completed in 2025, underscoring growing investor confidence in Boldr's mission.

Madi Ablyazov, CEO and co-founder of Boldr, articulated the company's strategic vision: "The future power grid will be decentralized, composed of millions of homes working in concert. Achieving this scale requires empowering the contractors who are already on the front lines of installing and maintaining home energy systems. Our focus is to equip them with the technology necessary to build this distributed energy future." This approach directly targets the crucial role of HVAC professionals in enabling grid flexibility.

Boldr's funding aligns with a notable trend of increased investment in European climate technology, particularly in building energy management and grid flexibility solutions. Recent significant rounds in the sector include €21 million for Axle Energy, €10 million for GALVANY, €7.8 million for Companion.energy, €40 million for metiundo, and €11 million for Capalo AI, among others, collectively representing over €156 million in 2026 capital deployment. This highlights a dynamic market actively seeking solutions for energy efficiency and grid stabilization.

Alexis Horowitz-Burdick, Partner at Unconventional Ventures, commented on Boldr's market position: "Boldr is addressing a critical infrastructure challenge for the coming decade: creating scalable, affordable grid flexibility. By recognizing HVAC contractors as key partners in home electrification, Boldr is developing technology that not only improves contractor efficiency and customer service but also unlocks substantial distributed grid capacity. This positions them as a pivotal player in residential energy management."

Founded in 2022, Boldr's platform aims to connect various in-home systems, starting with HVAC. The company's long-term objective is to integrate heating and cooling, battery storage, EV charging, and solar installations into a unified network capable of intelligently managing electricity demand in response to grid needs. A key differentiator is Boldr's strategy of collaborating with existing contractor networks rather than solely targeting consumers directly, facilitating rapid deployment and scalability.

The company's Universal Thermostat offers a hardware-agnostic solution designed to streamline installations for HVAC professionals. Its wireless architecture, which separates the control module from the equipment-side subbase, can reduce installation labor costs by up to €428 per unit. Furthermore, each installed device provides real-time telemetry to Boldr's cloud platform, enabling remote diagnostics and proactive maintenance, thereby minimizing the need for on-site technician visits.
