BSV Podcast 0126: Arceon

Balerion Senior Associate Aidan Daoussis sits down with Rahul Shirke, Founder & CEO of Arceon, to discuss advanced composites for space and defense. Arceon develops ceramic matrix composite components for extreme environments, including rocket nozzles, heat shields, leading edges, and hypersonic aeroshells. The company is focused on faster, scalable production of high-temperature materials for space and defense applications.Timestamped Overview00:00 – Introduction and Arceon company overview02:34 – Rahul Shirke’s background and the founding of Arceon03:49 – Extreme environments in solid rocket motors and hypersonics05:32 – How advanced materials simplify high-temperature systems06:28 – Arceon’s manufacturing process from polymer composite to ceramic matrix composite09:37 – Technical differentiation and faster production timelines11:05 – Company milestones, space projects, and defense qualification12:03 – Changes in the European space and defense ecosystem15:06 – Customer drivers: scale, weight reduction, reusability, and manufacturability16:32 – Comparison with Inconel and other high-temperature metals19:59 – Carbon fiber, proprietary resin, silicon infiltration, and damage tolerance22:29 – Static fire testing, AFRL testing, and nozzle extension development25:03 – Fundraising, government support, and scaling challenges in Europe27:04 – Demand split between defense and commercial space28:07 – Future implications for lunar infrastructure and hypersonic systems34:00 – Near-term milestones in heat shields, nozzle extensions, and defense production36:38 – Why scalable materials production may now be venture-backable39:28 – Process know-how, reproducibility, and barriers to copying Arceon43:47 – Why advanced materials matter across space, defense, semiconductors, and nuclear This is a public episode.
