## About

Founded in 2023 and based  in Tokyo, Japan, cosmobloom specializes in aerospace structural solutions. In August 2026, cosmobloom raised JPY 330 million in Seed funding from Toyota Invention Partners, Sega Sammy Holdings, Pola Orbis Holdings, Animal Spirits, Asia Defense Innovation Fund LLC, Z Venture Capital and Taiyo Kogyo Corporation.

Cosmobloom specializes in advanced flexible structural systems for aerospace applications, concentrating on the analysis, design, and development of deployable structures. Their core products, including the NEDA (Nonlinear Elastic Dynamics Analysis) code, have been crucial in simulating the deployment of solar sails, notably in projects such as JAXA’s IKAROS. They also develop ultra-lightweight antennas for small satellites and deorbiting devices, serving clients from governmental space agencies to private aerospace firms, primarily within Japan and the broader Asian markets, as well as internationally. Their focus on innovative solar power systems, including solar sails and star shades, positions them as contributors to next-generation space technology.

Cosmobloom’s revenue model relies on B2B transactions, especially through contracts with governmental and commercial space organizations. Their flagship products are sold through direct partnerships, involving project-based contracts tailored to client mission requirements. This model fosters long-term client relationships, which ensure recurring revenue opportunities through ongoing support and updates, although specific pricing structures remain undisclosed.

The company plans to use the August 2026 funding to advance space technology development and expand its team to support growth in the communications, space infrastructure, and defense sectors.
