Fixing the flow of elective care by making every list count.

We’re a small, focused team with decades of joint experience supporting NHS hospitals to plan and deliver care more effectively. Our tools are built to solve real operational problems and cut through complexity - not add more.

Our ambition is simple: help surgical teams deliver more care with less chaos.

We’ve sat alongside transformation teams, data analysts, and clinical leads. We know the frustrations, the workarounds, and the weight of the backlog. That’s why Tetra is designed with the NHS in mind - pragmatic, easy-to-use, and ready to make change easier.

Our mission

We empower hospitals to make the best use of their resources and deliver more care, through intelligent patient and resource coordination.

Why we exist

We’ve seen the pressure NHS teams are under. The never-ending backlog. The last-minute changes. The frustration of underused lists and on-the-day cancellations. Too many systems and tools promise transformation but deliver admin. At Tetra, we believe surgical scheduling is an optimisation problem, not a personnel problem. That means letting technology pick up some of the time-consuming processing, so teams can focus on patient outcomes.

Led by strong values

Affordable, but not basic

We know the financial demands on every provider and know what it's like being on the other side of the purchasing decision. That's why we believe in affordability for every specialty, hospital and provider. At every price point, Tetra provides a significant return on investment.

Solve what matters

Too many systems are "nice-to-haves" - or claim to "support data-driven decision making" without showing real impact. We build tools that solve concrete problems, delivering clear booking advice that’s statistically proven to increase throughput.

Accessible by design

We design tools for our users. We do not overcomplicate or prioritise complicated features that users will not engage with. We focus on the fundamentals - providing tools that are easy to understand, get the job done, and just work.

Data security above all

We appreciate the sensitivity of the data you hold, and how difficult it can be to agree to share it. That's why we incorporate best-in-class practices, like pentesting at more frequent intervals than mandated, and end-to-end encryption - we do not store direct patient identifiers on our databases.

Flexible and adaptive to your needs

We recognise that there might be local ways of working, processes, and transformation that have worked for you, and not everything should be upended. That's why every deployment takes into account the things that work for you, and Tetra aims to support you with what's already making a difference.

Human problems, solved by AI

Too many AI or machine learning models are solutions looking for problems. We believe AI should serve frontline staff, not the other way around - every model we build starts with a need, not a novelty. We start with real-world challenges and use AI to solve them in practical, human-centered ways.
