Radius Capital

Radius Capital invests in early-stage deep tech, software, and AI companies that enable next-generation aerospace capabilities. The firm targets technologies across the aerospace value chain, including design and development tools, advanced manufacturing, robotics, and autonomous flight systems. While anchored in aerospace, these cyber-physical systems often have applications that extend into broader industrial and defense sectors.

Founder and Managing Director Peter Shannon and Partner Luka Tomljenovic lead the firm. Shannon co-authored the national Advanced Air Mobility strategy through the National Academies and advises NASA. Tomljenovic is a former Croatian Air Force fighter pilot and was previously a Partner at Airbus Ventures, where he led investments in aerospace technologies.

The firm invests in the full stack of enabling technologies — software, AI, robotics, and advanced manufacturing — that power complex cyber-physical systems. While many portfolio companies produce physical systems such as drones or robotic manufacturing cells, the thesis is built around the intelligence layer, design tools, and autonomous capabilities that make those systems viable.

Sourcing draws heavily on the firm's institutional advisory roles. Peter Shannon's ongoing work with NASA's Aeronautics Research and Technology Roundtable and the National Academies' Transportation Research Board provides visibility into emerging technical requirements and research. The firm's podcast, The Vertical Space, also serves as a platform for engaging founders and operators across the aerospace innovation ecosystem.

Radius Capital makes direct early-stage investments into portfolio companies. There is no public disclosure of fund-of-fund commitments or participation in external venture funds. The firm's model centers on concentrated, domain-specific direct investing.
