Seraphim Space, the world’s leading SpaceTech investor, today announced the launch of its Resilience & Growth Programme in partnership with the Japan External Trade Organisation (JETRO). The programme is designed to equip participants with the networks, market insight and commercial foundations needed to establish and scale their presence across the UK and wider European markets.
Kicked off at SPACETIDE in Tokyo in early July 2026, the programme brings together ten advanced Japanese space and deep-tech companies. Over the next five months, participants will receive tailored support from Seraphim and a network of leading industry organisations, including ADS, Crowell & Moring and other ecosystem partners. Through a combination of expert guidance, strategic introductions and market access assistance, the programme will help companies:
- Navigate European regulatory and procurement frameworks
- Develop commercial relationships with leading aerospace, defence and industrial organisations
- Connect with institutional investors and strategic sources of capital
- Engage with senior decision-makers across government and industry
Following the launch in Japan, the cohort travelled to the UK for the Farnborough International Airshow, engaging with potential customers, investors, partners and policymakers from across the global aerospace sector.
Alexander Holt, Managing Director at Seraphim Space Enterprise, said:
“Europe is entering a period of unprecedented investment and urgency across space and aerospace capabilities. At the same time, Japan is home to some of the most advanced and scalable technology companies in the sector.
“Through this partnership with JETRO, we are bringing those two forces together — enabling a new generation of world-class Japanese companies to access European markets, capital and strategic partnerships.
“These are not early-stage startups; they are proven businesses with the capability to deploy and scale internationally. Our role is to help unlock that growth and build meaningful, long-term collaboration across allied ecosystems.”
The programme draws on Seraphim’s longstanding experience supporting specialist startups in the space sector through its growth programmes, which bring together key stakeholders across the SpaceTech ecosystem helping companies scale. Since its inception in 2018, 119 startups from more than 30 countries have been through Seraphim’s growth programme and raised over $1.6bn in investment. Designed specifically for high-growth, scale-ready businesses, this cohort includes companies already established in Japan with significant technical maturity, spanning areas such as satellite data and imagery, propulsion, advanced materials, precision navigation and maritime technologies.
The initiative comes at a time of accelerating investment in European space technologies, driven by shifting geopolitical dynamics and a growing focus on sovereign capability. European investment increased by 26% in 2025 as governments and industry ramped up demand for technologies that enhance security, resilience and strategic autonomy.
However, despite this growth, Europe’s SpaceTech ecosystem remains relatively nascent compared to more mature markets, with smaller deal sizes and less growth capital available. The programme will therefore also explore how advanced Japanese technologies and engineering expertise can play a critical role in supporting Europe to scale its next generation of defence and space capabilities — strengthening collaboration between allied nations at a pivotal moment for the sector.
