Letara Ltd., a startup specializing in the development and manufacturing of spacecraft propulsion systems using plastic as fuel to achieve "safety, affordability, and high thrust," has been selected as a 5th batch company for the "J-Startup" program, a startup support initiative operated by the Ministry of Economy, Trade and Industry. Led by Co-CEOs Landon Kamps and Shota Hirai.
J-Startup
J-Startup was launched in June 2018 with the mission of fostering startups with the potential to make a global impact. This program identifies promising startups based on recommendations from experienced venture capitalists, corporate innovation leaders, and other external experts. Selected startups receive intensive support from both government agencies and private sector ‘J-Startup Supporters.’ The program is jointly administered by the Ministry of Economy, Trade and Industry (METI), the Japan External Trade Organization (JETRO), and the New Energy and Industrial Technology Development Organization (NEDO).
Under this initiative, NEDO provides R&D funding support, JETRO facilitates international expansion, and METI offers preferential consideration in various government screening processes. Additionally, private sector partners contribute valuable collaboration opportunities and mentoring services, creating a comprehensive ecosystem to empower Japanese startups to compete and succeed in the global
marketplace.
Letara’s Vision "Anywhere in space within 24 hours“
Letara Ltd., a Hokkaido University recognized start-up, was founded to implement the decades of research conducted at Hokkaido University. By using plastic-based fuels and nitrous oxide, Letara has been able to mitigate key issues associated with traditional rocket motors, including high costs, safety risks, and potential for explosion. Letara has succeeded in developing a safe and affordable hybrid propulsion system while simultaneously maintaining the high thrust desired in conventional liquid and solid rocket propulsion systems.
