Boom Supersonic announced a $300 million Series B round led by Darsana Capital Partners, with participation from Altimeter Capital, ARK Invest, Bessemer Venture Partners, Robinhood Ventures and Y Combinator. The financing backs the company’s new Superpower natural-gas turbine business and provides a revenue stream to fund the development of its Overture supersonic airliner. Crusoe, an AI-focused data-center operator, became the launch customer, placing an order for 29 Superpower units that together generate 1.21 GW of power.
The round gives Boom a fully funded runway to deliver its first turbines, expand production capacity, and accelerate the certification of the Overture jet engine, all while creating a new, high-margin industrial business that leverages the same supersonic-grade technology that powers its aircraft.
Funding Overview
The $300 million Series B was anchored by Darsana Capital Partners, a New York-based firm with deep aerospace, AI and defense expertise. Co-investors include Altimeter Capital, ARK Invest, Bessemer Venture Partners, Robinhood Ventures and Y Combinator. According to Boom’s CEO Blake Scholl, the capital “fully funds Symphony engine development, and ongoing revenues from the Superpower business will finance certification and delivery of Overture.” The round also solidifies Boom’s balance sheet, enabling it to pursue a multi-gigawatt production ramp without diluting the company’s long-term capital efficiency.
Launch Customer, Crusoe
Crusoe has committed to 29 Superpower turbines, a 42 MW natural-gas unit packaged in a shipping-container-scale enclosure. The order totals roughly 1.21 GW of capacity and is valued at about $1.25 billion. “Boom’s innovative approach to power turbine technology builds on the company’s impressive breakthroughs in supersonic flight,” said Chase Lochmiller, co-founder and CEO of Crusoe. “We’re proud to be partnering closely with Boom as the launch customer for Superpower, an initiative that aligns perfectly with Crusoe’s energy-first approach to building the AI infrastructure of the future.” The deal gives Crusoe a water-less, high-temperature-tolerant power source for AI and HPC workloads that are increasingly constrained by traditional turbine performance.
Superpower Turbine Technology
Superpower derives 80% of its parts from Boom’s Symphony supersonic engine, repurposing aerospace-grade materials and high-temperature cycle designs for stationary power generation. Each unit delivers 42MW of ISO-rated output in a container-sized package, maintains full rated capacity at ambient temperatures above 110 °F, and operates without a dedicated water supply, an advantage for arid data-center sites. The turbines run on clean natural gas with optional diesel backup, offering a flexible fuel mix while targeting 39% efficiency comparable to other aeroderivative turbines.
Production Ramp & Manufacturing Roadmap
Boom plans to scale turbine output to “more than 4 GW annually by 2030,” a target that builds on its current backlog of over $1.25 billion. Initial units will be produced at existing facilities, with a dedicated turbine factory slated for announcement in 2026. The company has outlined incremental milestones: 1 GW in 2028, 2 GW in 2029, and 4 GW in 2030. This trajectory positions Superpower as a domestically manufactured, high-performance alternative to imported aeroderivative plants and supports broader U.S. reindustrialization goals.
Why Zillionize Invested
Boom is a rare combination of aerospace engineering excellence that caters to critical infrastructure. Boom’s ability to monetize its supersonic engine technology through Superpower provides a tangible, revenue-generating business that de-risks the capital-intensive Overture program. In short, Boom’s supersonic heritage, proven engineering, and emerging power-generation market make it exactly the type of high-tech venture that Zillionize looks for.
