Antora Energy Raises $550 million in Funding

Investors Behind the Funding

The round was backed by G2 Venture Partners and Eclipse (co-leads), alongside G2 Venture Partners, Eclipse, Ribbit Capital, Salesforce Ventures, Activate Capital, John Doerr, Westly Group, StepStone Group, Liberty Mutual Strategic Ventures, Decarbonization Partners, Impact Science Ventures, Trust Ventures, Breakthrough Energy Ventures, Lowercarbon Capital.

Company Profile and Market Context

Antora Energy operates in Industrials & Manufacturing. Surging AI data-center and heavy-industry electricity demand has pulled long-duration and thermal storage back into favor after a weak cleantech funding stretch, making this one of the largest cleantech rounds of 2026. Investors are rewarding companies that have moved past pilot stage to demonstrable manufacturing throughput and on-schedule deployment. Reshoring and domestic-supply-chain framing is now standard in US energy hardware pitches.

Strategic Use of Funds

Accelerate nationwide deployment of large-scale projects, expand production capacity, establish a second U.S. manufacturing hub, and strengthen the domestic supply chain.

Looking Ahead

"From factories to data centers, energy is the bottleneck to industrial growth. Antora has shown we can help break that bottleneck-delivering energy fast, at massive scale, with American innovation." - Andrew Ponec, Co-Founder and CEO, Antora Energy
