Halcyon raises $21 million

AI platform for energy Halcyon has raised $21 million in a Series A round led by Energize Capital, with participation from Zero Infinity Partners, Congruent Ventures, Obvious Ventures, and Sabanci Climate Ventures. To date, the company has raised ~ $32 million.

Founded in 2023, San Francisco-based Halcyon offers an AI platform designed to help energy professionals navigate complex regulatory and market data, enabling faster decision-making across areas such as data center siting, infrastructure investment, and energy development. The company aggregates and structures data from US regulators, including public utility commissions, ISOs, RTOs, and the Federal Energy Regulatory Commission, and combines it with AI tools for search, monitoring, and analysis.

“We’ve been humbled by the breadth of customer interest and use cases we’ve uncovered over the past two years, and we’re just getting started. The energy and AI buildout is one of the defining economic stories of our time, and the opportunity to apply modern compute, machine learning, and AI to it is bigger than we imagined. This fundraise means more resources to put to work for our customers, and we’re grateful to Energize Capital and everyone who’s supported us, challenged us, and pushed us to do better.” – Bruce Falck, CEO and co-founder of Halcyon.

“As the market for energy infrastructure grows, the volume and complexity of energy data crucial to decision-making is becoming increasingly difficult to access and analyze. In the U.S. alone, up to $850 billion will be invested in power and digital infrastructure in 2026, underscoring the need for timely, high-quality intelligence to inform decisions around capital allocation. Halcyon combines specialized energy industry expertise with a highly customized AI solution that makes it easier for customers to track, query and derive insights from large magnitudes of continuously evolving energy data.” – Tyler Lancaster, Partner and Co-Head of Ventures at Energize Capital.
