We are excited to share that Energize Capital has closed Ventures Fund III, totaling $430 million in capital commitments to the fund and its related vehicles, marking our fifth institutional fund and third of our Ventures strategy. This fund will back earlier-stage companies focused on scaling and empowering the next chapter of energy and industrial innovation through digital and software-enabled solutions. This latest raise brings Energize's total assets under management to over $1.8 billion, strengthening our capacity to support visionary entrepreneurs both through financial capital and our dedicated portfolio services platform, Energize EDGE.
For nearly a decade, Energize Capital has invested in climate solutions with ambition. In that time, we’ve partnered with some of the foremost founders across energy and industry—leaders who are building and operating at the intersection of digital innovation and climate to create a modern sustainable economy. Today, we’re announcing the latest chapter in our journey: the close of our oversubscribed Energize Ventures Fund III, with $430 million in capital commitments across the fund and its related vehicles. This marks our fifth institutional fund and the third dedicated to our Ventures strategy, reinforcing our conviction that climate solutions aren’t just indispensable—they’re only getting started.
Since we started investing, the climate solutions landscape has expanded far beyond what we thought was possible. Climate tech is no longer a siloed set of emerging technologies, but an essential lens that cuts across industries and underpins the global economies. The reshoring of manufacturing, the digitization of industrial operations, and the rise of the circular economy are reshaping physical infrastructure—and each of these shifts depends on software to optimize performance, reduce waste, and manage complexity. AI is accelerating this shift, enabling smarter forecasting, automation, and decision-making across critical systems. And in the U.S., where nearly all new energy capacity is now renewable, software is essential to integrating clean power and balancing a more dynamic, distributed grid. Together, these forces have created a reality where climate solutions are foundational to a stable, modern society. Even amid political shifts, market uncertainty, and workforce transitions, our conviction remains unchanged: the next era of growth depends on an economy that is sustainable, efficient, and digitally enabled.
That’s why we raised Ventures Fund III, our largest fund to date, oversubscribed and raised at record speed. Ventures III will function within our existing Ventures strategy, backing earlier-stage companies focused on scaling and enabling the new energy and industrial landscape through digital and software-enabled solutions.
This fund has been made possible by our new and returning limited partners, who represent world-class institutional, strategic, impact, and family office investors. We’re proud to welcome a new group of institutional names from across the U.S. and Europe into our LP base, including Första AP-Fonden (AP1), Capricorn, Reference Capital, Keeling Capital, Keysight Technologies, WEX Venture Capital, and several other international pensions. We remain grateful for the enduring support from existing investors, including GE Vernova, CDPQ, Builders Vision, UBS, WEC, and others. These partners share our conviction in the necessity of climate solutions and see the value of technologies that demonstrate durable growth, maintain sustainable revenue models, and address critical customer challenges.
"We have spoken to hundreds of venture managers focused on the energy transition and Energize stood out strongly with their thoughtful, self-reflective, and clear-eyed approach, as well as their deep domain expertise,” said Béla Hanratty, Managing Partner of Keeling Capital. “They have shown themselves to be outstanding partners, and we're excited to be a part of what they are building."
"As a leader in the mobility sector, WEX is experiencing firsthand how electrification could change our industry—requiring us to navigate energy markets in new ways," said David Klein, Head of WEX Venture Capital. "We chose to partner with Energize because their specialized expertise and investment theses across electrification, digitization, and energy infrastructure give us the insights to capitalize on this shift. We believe the energy transition will open new profit pools across the economy, and Energize is a great partner to help us unlock them."
In Ventures III, our initial investments will primarily target startups raising Series A, B, or C rounds. We will continue to rely on our research-driven approach, investing in asset-light companies that solve challenges across our thesis areas of electrification and mobility, industrial operations, decarbonization, infrastructure resilience, and renewable energy. As with our previous investments, we will prefer to lead rounds and take active partnership positions as engaged board members.
To date, Energize has deployed capital from Ventures III into five total investments, including Tyba, a battery optimization platform enabling profitable BESS deployment; Archive, a technology solution that works with global brands like The North Face and lululemon to launch and scale resale businesses; and Nira Energy, a profitable software platform that supports grid interconnection for energy developers. These investments represent our belief that there are growing opportunities today across the rich ecosystem of energy storage, grid software, and resource optimization.
Through this new fund, we will continue to identify and support leading innovators across these spaces and more.
“We partnered with Energize because we wanted strategic investors who understand our product within the complexities of the energy transition—and who can support us for the long haul,” said Chris Ariante, CEO and Co-founder of Nira Energy. “Scaling an energy software company comes with unique challenges that require deep, sector-specific expertise. As we expand into new products and customer segments, Energize has already brought insights, connections, and support that are helping us accelerate growth.”
Within Ventures III, we remain committed to being strong partners with our portfolio companies, both by taking board seats and through Energize EDGE. Today, our EDGE team represents over a quarter of our firm’s headcount and consists of seasoned industry experts dedicated to creating and preserving value across our portfolio. We provide in-depth support through five core pillars: go-to-market, finance and operations, impact, communications, and talent. This in-depth portfolio support remains a priority for Energize and an essential resource for our portfolio companies.
“We’re excited to partner with Energize Capital as part of their Ventures Fund III,” said Emily Gittins, Co-founder and CEO of Archive. “Since Energize has joined our cap table, we’ve already seen the benefits of being part of the Energize platform—from talent support to financial operations. We’re looking forward to deepening our work with their team as we scale resale marketplaces into a core, profitable channel for brands worldwide.”
We’re in a defining moment for climate solutions—one where the entrepreneurs who succeed will be those building not just fast, but with durability, intentionality, and vision. Ventures Fund III is for founders creating asset-light, digital solutions that meet the urgent demands of the energy transition while standing the test of time. At Energize, we’re here to be long-term partners to these builders and operators—providing the capital, expertise, and support they need to scale. If you’re building solutions that will power the sustainable economy, we want to hear from you.
Let’s get to work.
