Like a lightning bolt charging a green revolution, Energize Capital has plugged in $430 million in new funding to fuel the next wave of digital climate innovation. On Tuesday, the climate-focused venture firm announced the close of Ventures Fund III, marking its most electrifying push yet into asset-light climate solutions aimed at transforming energy and industrial systems.

The new fund, backed by an array of institutional and strategic partners, raises Energize’s total assets under management to a formidable $1.8 billion—solidifying its position as a heavyweight in the climate tech investing arena.

From Software to Substations: A Digital Vision for Decarbonization

Focused on earlier-stage companies operating at the crossroads of software, energy transition, and industrial digitization, Ventures Fund III targets what Energize calls “asset-light” solutions—companies with brains over brawn, wielding code instead of concrete.

“Operators today need more than just capital—they need specialist investors with domain depth and scaling experience,” said John Tough, managing partner at Energize. “Having weathered multiple market cycles, we understand how climate solutions have grown in complexity and potential.”

Energize intends to deploy the fund into ventures that push the boundaries of energy and infrastructure through innovative software, particularly platforms that enable better energy storage, grid interconnection, and sustainable commerce.

Early Bets: From Battery Brains to Resale Revolutions

Fund III has already energized a handful of promising startups, including:

• Tyba – A cutting-edge platform optimizing battery software performance

• Archive – A tech startup helping fashion brands launch and scale resale operations

• Nira – A digital grid interconnection tool aiding energy developers in navigating utility hurdles

These companies represent a broadening landscape where software eats carbon emissions, and technology reimagines industrial systems from the inside out.

A Deep Bench of Backers

The capital surge was made possible by a diverse syndicate of new and returning limited partners, including global pensions, corporate strategics, and impact-focused family offices. New backers include Första AP-Fonden, Capricorn, Keeling Capital, Reference Capital, Keysight Technologies, and WEX Venture Capital.

Veterans from past funds also returned, including GE Vernova, CDPQ, Builders Vision, UBS, and WEC. For Builders Vision’s Scott Gerdes, the decision was clear: “Energize brings unmatched industry insights and operational muscle to help software-based energy transition companies break through and scale.”

A Green Future, Supercharged by Code

With climate urgency rising and the demand for scalable clean technologies at an all-time high, Energize Capital's Ventures Fund III arrives as a force multiplier—amplifying the reach of early-stage solutions through strategic capital and deep industry know-how.

As the energy transition gallops ahead, Ventures Fund III isn’t just a financial tool—it's a power converter, turning bold ideas into grid-shifting reality.

Legal counsel involved in the transaction was not immediately available Tuesday, and Energize Capital declined to comment further.
