Energy management startup Boldr has successfully secured $5 million in new funding to advance its mission of transforming residential energy consumption. The round, led by Unconventional Ventures, will fuel the launch of a new generation of HVAC controls designed specifically for contractors. Boldr aims to empower these professionals with technology that simplifies installations and enhances long-term service capabilities.


A Contractor-Centric Approach to HVAC Control

Boldr distinguishes itself by focusing on HVAC contractors rather than marketing directly to homeowners. The company views these technicians as the essential deployment and service network for its smart energy technology. This strategy positions contractors at the forefront of integrating homes into a more flexible and efficient energy grid.

At the heart of this initiative is the new Boldr Universal Thermostat, engineered for exceptional compatibility. It is designed to function seamlessly across a wide array of North American HVAC equipment, including both ductless and central systems. This versatility makes it a uniquely flexible tool for technicians who work with diverse heating and cooling technologies.

Solving Installation Challenges with Wireless Technology

A key innovation of the thermostat is its wireless architecture, which directly addresses a common installation obstacle. Technicians frequently encounter insufficient control wiring when upgrading systems, leading to complex and time-consuming work. Boldr's device communicates wirelessly with an equipment-side subbase, eliminating the need to run new wires.

This wireless solution offers significant financial and operational benefits for HVAC businesses. Boldr estimates that it can save contractors between $300 and $500 in labor and materials on applicable jobs. This efficiency allows technicians to complete work faster, increasing productivity and enabling them to handle more service calls.

Beyond Hardware: A Platform for Growth

The company's offering extends beyond physical hardware to a comprehensive software platform. Every installed thermostat connects to Boldr's contractor portal, providing businesses with valuable data and diagnostics. This connectivity gives them unprecedented visibility into their entire installed base of equipment.

This platform is designed to help contractors improve operational efficiency and build stronger customer relationships. It enables early problem identification, reduces unnecessary truck rolls, and provides deep equipment insights. For scaling HVAC businesses, this technology is crucial for increasing customer retention and generating recurring revenue.

Fueling Expansion and a Vision for the Future

The new $5 million in capital will be strategically deployed to accelerate the company's growth. Funds are earmarked for expanding from ductless controls into residential and commercial central HVAC systems. The investment will also support further development of the contractor platform and expand distribution partnerships across North America.

Boldr's long-term vision involves creating a decentralized energy network powered by interconnected homes. The company plans to extend its platform to manage other residential assets like batteries, EV chargers, and solar installations. This network would collectively manage energy demand, providing crucial flexibility and capacity to the power grid.


This latest funding round marks a significant milestone for Boldr, validating its unique contractor-focused strategy in the competitive energy technology sector. By providing practical tools that solve immediate challenges for technicians, the company is building the foundation for a more sustainable energy future. Boldr is positioning itself not just as a thermostat maker, but as a key enabler of the distributed power plant of tomorrow.
