Online Oceans raises £4m in seed funding led by Seraphim Space to scale autonomous fleet manufacturing.
The seed round was led by Seraphim Space with backing from prominent technology founders and investors.
Online Oceans builds autonomous surface vessels and cloud-based software for persistent maritime coverage and security. The company operates from London and serves defence and commercial markets.
Online Oceans has secured £4m in seed funding led by Seraphim Space to scale manufacturing and support ongoing deployments. The round drew participation from a group of high-profile backers, including Peter Rive, Frank Thieser, Florian Seibel and Koro Capital.
Founded in early 2025, the London-based business develops autonomous surface vessels and command platforms designed to provide continuous maritime monitoring at scale. The fresh capital will be directed towards expanding production capabilities and meeting rising international demand across defence and commercial sectors.
From the founder
"Persistent maritime coverage has been too expensive for too long. That has limited what governments and operators can actually see, protect and respond to at sea. We built Online Oceans to change that. This funding allows us to scale production and support customers who need a far more practical way to monitor critical waters, protect infrastructure and maintain awareness over long periods."
George Morton
Founder and CEO at Online Oceans
Investor perspective
"Online Oceans is building a category-defining company at the intersection of defence, maritime autonomy and data. The breakthrough here is not just a lower-cost vessel. It is a new coverage model: dense, persistent fleets that can monitor critical waters continuously rather than sporadically. What impressed us was not just the technical insight, but the speed of execution. In little over a year, the team has moved from founding to production ramp, early customer traction and first data sales. We believe they have the potential to build a global leader in this category."
