About Us

At River API, we help UK companies build the technical backbone their business needs to succeed. Whether it’s weaving disconnected systems, rethinking complex integrations, or powering up your stack with API integrations and AI, our experts bring structure to the chaos and precision to the plan.
We’re a UK-based API and AI development company with distributed engineering teams across Europe. Our software team specialises in rebuilding failed architectures, delivering essential integrations under pressure, and shipping clean, stable APIs for platforms that can’t afford to fail.
From fast-growing SaaS startups to established enterprises, we work with companies ready to scale. You bring the business case. River API brings the team, the architecture, and the execution.
The stack? Deep. We speak Python, Node.js, FastAPI, Postgres, Kafka, AWS, LangChain, GraphQL, and enough experience with legacy systems to know exactly where things break and how to fix them.

Why Us?

We tidy up what others left behind

Half-built APIs. Failing integrations. Systems that “almost work.” River API specialises in fixing what others left behind. If your infrastructure is held together with quick fixes and messy code, our engineers will rebuild it right.

UK-rooted, Europe-backed

You get the clarity and consistency of a UK-headquartered partner, with the technical firepower of senior engineers across Europe. No communication gaps, just focused delivery.

Built for outcomes

We write scalable code, but we start with sharp questions. How does this tie to growth? What’s the actual bottleneck? The result: APIs and AI solutions that serve your roadmap, not distract from it.

Flexible resourcing, real accountability

Need one specialist to fix your API integration layer? A full-stack team to lead the custom API development? River API shapes our involvement around your real-world needs and stays on until the job’s done right.
