Seraphim Space’s latest early-stage fund has surged past its $100 million target, marking a defining moment for the future of commercial space innovation. The new fund strengthens the firm’s position as the world’s leading SpaceTech-focused investor, now managing over $550 million across private and public vehicles. Backed by heavyweight institutions such as the British Business Bank, the National Security Strategic Investment Fund, and strategic corporates, including Arabsat, it builds on the support of long-standing partners Eutelsat, NEC, and SKY Perfect JSAT.
With headquarters in the UK and offices in the US and Germany, Seraphim deploys capital globally, targeting visionary entrepreneurs advancing space-enabled technologies. The fund is already supporting 17 standout companies across the US and Europe, each part of a wave reshaping how space capabilities intersect with the $100 trillion global economy.
A legacy that continues
Since 2016, Seraphim Space has been at the forefront of defining spacetech as a standalone investment category. Its ecosystem spans accelerators, dedicated venture funds and the London Stock Exchange–listed Seraphim Space Investment Trust, offering founders support from pre-incorporation through to pre-IPO.
Having backed 149 companies across 33 countries, with over £10 billion raised and nine unicorns, the firm has become a global benchmark for how to build and scale space-first ventures.
With this new oversubscribed fund, Seraphim is not just investing in spacetech but is shaping the next era of strategic, scientific, and economic transformation driven by space-enabled innovation.
The latest bet
The fund’s newest investment is Mutable Tactics, which highlights Seraphim’s thesis that autonomy will define the next decade of space and defence technology. Based in Cambridge, the startup has created a decision layer that allows unmanned systems, across air, sea, and land, to operate together even when communications degrade.
By translating a commander’s intent into executable actions, the system enables drone fleets to coordinate, adapt and function independently of GPS or stable networks. With its own funding round expected to close soon, Mutable Tactics stands out as a crucial enabler of resilient autonomous operations.
Portfolio of investments
Seraphim’s portfolio is broad, capturing the diverse ways orbit-driven intelligence and infrastructure now influence life on Earth.
In defence, companies like Auriga, Atmos Space Cargo, General Galactic and Privateer are building technologies that ensure safe access to and control of contested space environments, an area rapidly becoming inseparable from national security.
On the climate front, firms such as Delos, Adaptive Insurance and Renoster use the fusion of space data and advanced analytics to drive breakthroughs in climate resilience, monitoring, and risk management. These tools are helping institutions and governments plan for escalating environmental challenges with unprecedented precision.
Meanwhile, in life sciences, LambdaVision is pioneering work made possible only in microgravity, developing innovations aimed at improving human health in ways Earth-based labs simply cannot.
Rebuilding the infrastructure that connects Earth and orbit
As launch costs fall and access becomes more democratic, a new cohort of companies is reinventing the infrastructure linking terrestrial and orbital systems. AscendArc, Array Labs, Constellr, Hubble Networks, PiLogic and Ubotica are developing novel sensing, communication, and compute capabilities that will accelerate everything from global connectivity to real-time Earth observation.
These ventures represent a shift from viewing space as a distant domain to recognising it as an extension of the world’s digital and industrial backbone.
Mark Boggett, Seraphim Space said, “Ten years on from raising our first SpaceTech fund, we are still only in the early phases of tapping into the immense opportunities that Space holds to transform all our lives. The recent SpaceX–xAI merger is a clear validation of Seraphim’s long-held view: SpaceTech is fast becoming the foundational enabler for artificial intelligence and digital systems that will power the global economy. This latest close of our current venture fund empowers us to continue championing breakthrough innovations that will shape industries and deliver meaningful, long-term benefits for our planet over the coming decade and beyond.”
Christine Hockley, Managing Director & Co-Head of Funds, British Business Bank said: “This investment is another example of the long-term impact of the Bank’s cornerstone commitments. We have been a partner of Seraphim since their first fund, and the firm has successfully carved out a niche in a rapidly advancing area of frontier technology. By making a cornerstone commitment to Seraphim, we are expanding the pool of capital available for the UK’s space entrepreneurs and helping a specialist UK fund manager to thrive.”
