Oshen develops 1.2-metre C-Star unmanned surface vehicles that are wind- and solar-powered, can operate autonomously for months, and send data by satellite. The robots are light enough for a single person to launch from a boat and are designed to operate in coordinated groups that can cover hundreds of miles or concentrate at specific locations. Oshen’s C-Stars were the first uncrewed vehicles to collect real data from inside a Category 5 hurricane, and the company’s longest mission lasted eight months at sea. Manufacturing is now based in Plymouth and output has scaled from 15 units produced over the company’s first three years to a cadence of 15 robots every six weeks, with 100 additional units ordered. Customers and collaborators include the US Navy’s Naval Meteorology and Oceanography Command and partners such as ZeroUSV and MarineAI on defence-related trials. The company has grown from seven employees in September 2025 to almost 30 employees as it pursues higher-volume, lower-cost deployments to compete with larger rivals like Saildrone, Sofar Ocean and Boeing’s Liquid Robotics.

Callosum’s platform sits between applications and hardware, decomposing AI inference workloads, matching sub-tasks to specialised models and processors, and routing execution to the most suitable hardware to balance speed, cost and precision. The company claims up to 4x speed improvements, 70% lower compute costs and a 10% higher task success rate on complex agentic financial workloads compared with running a single frontier model on conventional GPUs. A family of tailored inference APIs is being launched, with some APIs already in production for complex workloads in financial services. Callosum works with a range of silicon and infrastructure partners — including Cerebras, Rebellions, Axelera, Tendrils and Supermicro — and is a founding member of ARIA’s Scaling Inference Lab. The startup was founded by Danyal Akarca and Jascha Achterberg, who met while doing PhDs at Cambridge, and plans to use the new funding to scale the technology, deepen ecosystem partnerships and grow the team.

Gridcog builds energy modelling and simulation software used by businesses to plan and optimise decentralised clean energy projects. Its platform is already deployed by several global enterprises, including Shell, Greenvolt, Perth Airport, AGL and Ausnet Services. The company is Australian-founded and operates offices across the UK, Europe and Australia. Gridcog plans to use the $12.5 million Series A to deepen its technology platform and expand its commercial, customer and product teams. The company positions its software as significantly faster and more transparent than traditional spreadsheet-based modelling, aiming to support more bankable and accelerated energy transition projects.

Founded in 2022 as a spinout from University College London and the Faraday Institution, Gaussion develops an external magnetic charging approach that can be retrofitted to existing lithium-ion battery packs. Its two main products are MagLiB, a magnetic printed circuit board add-on for packs, and Aeon, a control chip and software platform that together form a smart control layer. The company claims faster charging and extended battery lifespan without changing cell chemistry or design and supports 14 active commercial programs across automotive, aerospace, grid storage and consumer electronics. Gaussion has filed 66 patent applications in 17 families and reported about 19 employees as of June 2025. In October 2025 it moved into a 40,000-square-foot R&D facility in central London. The company positions itself to capture demand from AI data centres, electric vehicles and grid-scale storage as the battery management market grows.
