The funding round was led by DTCP and values the British maritime defence company at over $1bn.
"Kraken is excited to be partnering with DTCP, leading such a prestigious group of European and international investors. This significant funding round will accelerate Kraken’s global roll-out, enabling the deployment of hardened, reliable, mission-ready capabilities for NATO and its worldwide partners at an unprecedented scale in the maritime domain,"
The round was led by Santander Alternative Investments to support the commercial rollout of the company optical ground station.
"It is an exciting moment for Archangel Lightworks to be able to announce this successful round of capital as the demand for space-based information and connectivity continues to grow exponentially. The Archangel Lightworks team has done incredible work designing, building, and deploying our laser communications systems, and now is the time for us to accelerate with our partners, new and old, to meet the needs that we are hearing from our customers across markets."
Seraphim Space led the pre-seed round to help accelerate development of the company decision-layer software.
"Increasingly, the constraint is no longer hardware but human attention. We can deploy more drones than ever before, yet we still ask operators to control them one by one, often in environments where communications are unreliable. True autonomy breaks that one‑to‑one link, allowing humans to supervise and direct teams of systems rather than individual machines. That shift is essential for supporting modern military missions, where scale, speed and resilience matter, and where operators must remain focused on intent and outcomes rather than manual control."
Amadeus Capital Partners led the seed round, which will fund team expansion and product development.
"We spent all our careers fighting criminal activity online and care deeply about elevating trust in the internet. The decision to develop the technology behind Refute came after seeing firsthand that disinformation targeting organisations was the next big threat vector, especially for commercial companies."
The financing was led by EMV Capital Partners and will support operational scaling and early customer deployments.
"We are pleased to have secured this significant investment from our existing shareholder base, and to welcome NSSIF as a new strategic shareholder. This support is a testament to the disruptive potential of Sofant’s technology and the remarkable progress our team has made in recent months. With this additional capital, we are positioned to accelerate our commercial deployment and redefine what is possible in wireless communications."
