Halcyon, an AI energy data startup, closed a $21 million Series A round to build out its product and expand its team, CEO and co-founder Bruce Falck tells Axios Pro exclusively.
Why it matters: Companies are looking for help accessing power more quickly.
Zoom in: Energize Capital, which invests in digital-focused energy and climate startups, led the round.
- Zero Infinity Partners, Congruent Ventures, Obvious Ventures and Sabanci Climate Ventures participated.
What’s next: The company, founded in 2023, plans to hire across engineering, sales and customer service. “We’re focused on nailing the product,” says Falck.
- Halcyon is riding the wave of energy demand growth. “The biggest uptake is essentially solving time to power,” says co-founder and chief strategy officer Nat Bullard.
Catch up quick: Halcyon was co-founded by Falck, Twitter’s former head of revenue product; Bullard, a long-time energy analyst; and engineer Alexander Huras, who’s Chief Technology Officer.
- The company raised a $10.8 million seed round in 2024 led by Obvious Ventures and Congruent Ventures and joined by Overture Climate VC.
How it works: Halcyon uses machine learning and large language models to aggregate documents and organize data from public utility commissions, energy regulators and grid operators.
- The company sells data subscriptions, like its natural gas plant tracker, and also enables customers to search and query the energy data.
- Halycon’s machines read between two and 20,000 new documents a day, and any of these documents could be between one and 20,000 pages, says Falck: “It’s an enormous volume of content.”
Customers include hyperscalers like OpenAI and digital infrastructure providers like Cloverleaf, as well as financial firms, energy developers, infrastructure companies and equipment providers.
Zoom out: Electricity demand is growing quickly for the first time in decades in the U.S., thanks in part to the deployment of AI data centers.
