A European software company for the age of AI agents.
NexusLayer builds the infrastructure AI agents need to do real work, builds its own products on that infrastructure, and helps organisations do the same. We combine long experience in enterprise Java with practical, production experience of AI, and we operate everything we build on our own servers in the European Union.
Three lines of business, one platform.
Each part of the company strengthens the others. What we learn operating our products improves the platform, and the platform is what we deliver for clients.
The layer
Infrastructure for AI agents: models, memory, knowledge, identity, secrets, workflows and observability.
20 servicesProducts
Focused applications for consumers and professionals, built on and proving the layer every day.
22 productsEngineering services
AI, Java and enterprise engineering for organisations that need dependable systems, delivered by the same team.

A clear, staged approach that produces evidence early and commits budget only once value is proven.

A working prototype on real data, built on the layer, with measurable success criteria agreed up front.
Deliver
Production engineering to enterprise standards, including security, testing, documentation and hand-over.
Operate
Optional managed operation in the EU, or a clean transfer to your own team.
Built to last
We design for the years a system will be in service, not for the demonstration.
Transparent
