Axle Energy announced a $25 million Series A funding round to accelerate its global expansion. The round was led by Energize Capital, with participation from returning investors Accel, Picus Capital, and Eka Ventures.

Axle Energy is building technology designed to connect distributed energy devices such as batteries, electric vehicles, and heat pumps into the broader energy system. The company’s goal is to help lower energy costs and reduce carbon emissions by making these distributed assets more useful and flexible at scale.

Since its founding three years ago, Axle Energy said it has shown that connected devices can play a central role in the future of energy. The company now supports more than 300,000 connected devices.

Those devices represent 2 GW of capacity, which Axle Energy noted is larger than a nuclear power reactor. This scale highlights the growing potential of distributed energy resources to support grid flexibility and cleaner electricity systems.

The new funding will help Axle Energy expand internationally and continue building infrastructure for a lower-cost, lower-carbon energy system. The company said the Series A will further its mission of unlocking distributed energy capacity from devices already deployed in homes and businesses.

The financing also reflects investor confidence in the growing role of distributed energy resources as electricity demand rises and grids require more flexible capacity. By coordinating devices such as batteries, EVs, and heat pumps, Axle Energy aims to help make clean energy systems more efficient, resilient, and affordable.
