## About

Portal Space Systems Inc. develops advanced aerospace solutions, specializing in multi-role spacecraft with ultra-high maneuverability for various orbital environments, enhancing operational flexibility across missions. Based in the US, Portal Space Systems Inc. focuses on the creation of innovative aerospace technologies. Portal Space Systems Inc. was co-founded by Jeff Thornburg (CEO), Ian Vorbach and Prashaanth Ravindran in 2021. In March 2026, Portal Space Systems Inc. raised USD 61.48 million in series A funding co-led by new investor Geodesic Capital and returning investor Mach33, with participation from other new investors Booz Allen Ventures, Ark Invest and returning investors AlleyCorp and FUSE. Other unspecified investors also participated in this round. Portal Space Systems specializes in advanced aerospace solutions, particularly focusing on the development of multi-role spacecraft designed for enhanced maneuverability and operational flexibility in various orbital environments. The company's flagship product, Supernova, is a highly versatile satellite bus engineered for ultra-high delta-V capabilities, allowing for rapid transitions between Low Earth Orbit (LEO), Medium Earth Orbit (MEO), and Geostationary Orbit (GEO). Supernova is equipped with radiation-tolerant technology and integrated space domain awareness sensors, providing critical data for mission planning and execution. The company aims to serve government agencies, commercial satellite operators, and defense contractors, particularly targeting clients in the United States and allied nations looking for innovative solutions in space operations. The existing product line is positioned to address the growing demand for agile, responsive space assets in an increasingly competitive space domain. Portal Space Systems generates revenue primarily through B2B transactions, focusing on partnerships and contracts with government entities, commercial partners, and defense agencies. The company engages in direct sales of its spacecraft and associated technologies, with potential revenue streams from service agreements and support contracts related to mission operations. Transactions occur through customized agreements outlining project scopes, timelines, and deliverables, catering to specific needs of each client. The pricing structure reflects the advanced engineering and technology integrated into its products, ensuring competitive positioning in the market. As the company expands its service offerings, revenue will come from both new sales and ongoing support contracts with existing clients, further solidifying its market presence in the aerospace sector. The company will use the March 2026 funding to support scale its growth and further development of its maneuverable spacecraft.
