- Online Oceans
Led · Equity · Apr 2026
Online Oceans develops autonomous systems for persistent maritime coverage, combining a compact solar-powered autonomous surface vessel called Scout with a cloud-based command-and-control platform named Tether. The platform enables operators to manage missions, monitor assets, and access real-time data for continuous, connected fleet operations. The company targets defence and security use cases including anti-submarine warfare, protection of subsea infrastructure, border security, and counter-drug smuggling. Founded in 2025 by George Morton and Alistair Douglas and based in the UK, Online Oceans is positioning its offerings as a lower-cost, scalable alternative to crewed vessels and limited autonomous deployments. Financially, the company has raised £4M in the latest round led by Seraphim Space to scale manufacturing and support deployments. The firm plans to expand deployments and capacity to meet growing demand across defence and commercial markets.
- ATMOS Space Cargo
Participated · Series A · Apr 2026
ATMOS Space Cargo develops free-flying orbital transfer and re-entry vehicles (PHOENIX family) and offers space logistics services to commercial, institutional, and defence customers. PHOENIX 2 is described as a free-flying spacecraft with integrated propulsion and power capable of missions from hours to several months in LEO, performing autonomous de-orbit and controlled atmospheric re-entry using an Inflatable Atmospheric Decelerator (IAD) that is non-ablative and acts as a heat shield and aerodynamic brake. The company plans an initial three-vehicle PHOENIX 2 fleet operated as a phased campaign and is preparing recovery operations near Santa Maria in the Azores under an ANACOM licence. ATMOS is also developing PHOENIX 3, a next-generation return vehicle with an intended payload capacity of roughly one metric tonne, about ten times PHOENIX 2’s capacity. To serve governmental and defence needs it is launching ATMOS WORKS, a dedicated dual-use business unit. The company raised €25.7M in a Series A to fund these activities, including the PHOENIX 2 build, ATMOS WORKS launch, and PHOENIX 3 development, with participation from the EIC Accelerator which provides blended grant and equity financing.

- Mutable Tactics
Led · Seed · Mar 2026
Founded in 2024 by Colin MacLeod and Enrique Muñoz de Cote, Mutable Tactics builds AI-powered autonomy for robotic systems and is based in London. Its flagship orchestration system, Mastermind, provides edge autonomy that allows robots to continue missions when GPS or communications are lost. The platform uses intent-based control so commanders set high-level objectives while the AI translates those into actions, and it is designed to keep humans in the loop for rules of engagement and ethical constraints. The software is hardware-agnostic and intended to work with low-cost, off-the-shelf drone hardware. The company raised $2.1M in a pre-seed round to validate its technology with two European governments and support continued product development. No revenue, user, or other operating metrics are reported in the article.
