Alumni Surpass $695M as Startups Address Global Defence, AI, and Space Sovereignty Challenges
London & San Francisco, [Date] – Seraphim Space, operating as Generation Space in the U.S., today announces the ten pioneering startups selected for Mission 15 of its world-leading SpaceTech Accelerator. Launched in 2018, the Seraphim programme has now supported more than 120 companies across 30+ countries, playing a vital role in building the infrastructure of the modern space economy. Collectively, alumni have raised $695.3 million in private funding, underscoring the sector’s momentum and growing investor appetite for space-enabled innovation.
As governments around the world, increase investments in sovereign launch, orbital defence, and dual-use AI, Seraphim’s Mission 15 cohort reflects this rising intersection of commercial opportunity and strategic capability. In Q1 2025 alone, private investment into space startups hit $2.1 billion, contributing to a 12% year-over-year increase in annual funding, now totalling $8.1 billion. Amid this backdrop, Seraphim continues to attract breakthrough companies pushing the boundaries of communications, Earth observation, in-orbit infrastructure, and national resilience.
Globalisation of Space: New Nations Enter the Arena
Mission 15 also signals the continued globalisation of the space economy, with startups selected from five countries, including the first-ever accelerator-backed company from Mongolia. As barriers to entry continue to fall, Seraphim is seeing increased participation from non-traditional space nations, reflecting how commercial access to space is becoming more inclusive, distributed, and geopolitically diverse.
“Each year, we see a broader spread of countries joining the new space race,” said Alexander Holt, Managing Director at Seraphim Space Enterprise. “This year, we’re proud to welcome our first Mongolian company. proof that space innovation is no longer the preserve of a few global powers. It’s a global movement, and Seraphim is at its core.”

“With Mission 15, we continue our commitment to identifying and supporting the brightest early-stage companies at the forefront of space innovation. The cohort arrives as our portfolio companies surpass an outstanding $695 million raised, a landmark figure that underscores not just investor confidence, but the real-world value these businesses are delivering. Many of these companies also reflect the growing fusion of commercial innovation with national strategic priorities—from orbital resilience to quantum cyber defences. This is the future of space, and we’re helping shape it.”
