Antares develops small modular reactors capable of producing roughly 100 kilowatts to 1 megawatt of electricity and designs its reactors to use TRISO fuel, which encapsulates uranium in carbon and ceramic shells. Its Mark-0 demonstration reactor reached criticality on June 4 at the Idaho National Laboratory. Antares is a finalist in the Pentagon’s Advanced Nuclear Power for Installations program and is pursuing deployments on Air Force bases in Colorado and Montana. The company plans to bring its first electricity-producing reactor online next year and targets military deployments in 2028. Financially, Antares has raised a total of $604 million to date, including a $96 million Series B in December and the $470 million Series C. The broader advanced nuclear sector faces challenges such as an immature U.S. supply chain and near-term cost competitiveness concerns; Lazard estimates new SMRs could cost about $214 per megawatt-hour, and Antares has not disclosed pricing.

MOTHER.tech develops Degen, an AI-driven creative app that lets artists, photographers, and designers package their visual style into one-tap generators ("gens") that users can apply to photos, references, or text. Each generator is created by a creator who earns a share of revenue every time their generator is used; the creator program is currently being tested and will open to all after launch. The app emphasizes speed, specificity, and subcultural aesthetics, releasing new generators daily and enabling users to remix, layer, and share results in private channels. Degen is available on iOS and Android by invite code with wider access planned following the seed-funded launch. MOTHER.tech was founded in 2023 by Kelsey Falter and Raissa Chagas and is based in Brooklyn.
