Zeno Power develops compact, long-duration nuclear batteries intended to provide reliable energy in frontier environments. Its systems target demanding maritime and space applications such as seabed infrastructure, highly maneuverable satellites, and lunar landers. The company has secured over $60M in contracts from the U.S. Department of Defense and NASA to develop these batteries. Founded in 2018 and led by CEO Tyler Bernstein, Zeno Power has 65+ team members. The company plans to use the new funding to grow its team to over 100 employees across Seattle and Washington, DC, and to invest in manufacturing capabilities to scale production and meet customer demand. This funding brings Zeno's total capital raised to over $70M following a Series A led by Tribe Capital in 2022. Zeno Power develops commercial radioisotope power systems, transforming nuclear waste (notably strontium-90) into compact heat sources for use in frontier environments from seabed installations to lunar missions. The company successfully demonstrated its first strontium-90 heat source at Pacific Northwest National Laboratory in late 2023. Zeno holds over $60M in contracts with NASA, the U.S. Navy, and the U.S. Space Force, signaling government demand for its technology. The firm is positioning its systems for both government space and terrestrial missions and is introducing a new category of power systems to the commercial market. To support development and operations, Zeno secured a revolving credit facility that provides working capital flexibility. No revenue or user metrics were disclosed in the articles.
