Element 52.
Rare by nature.
Tellurium is one of the rarest elements on Earth — and the name fits. We're the kind of development partner that's hard to find: one team that designs, builds and ships.
Who we are
Builders first.
Tellurium didn't start as an agency. It started as a team building real platforms — service desks, billing engines, booking systems — for real operations, including our own. That's still how we think.
When we take on your project, you're not getting a sales layer and a subcontracted dev team somewhere else. The people you talk to are the people writing the code — a fully remote team working across UK and US hours.
See the work that proves itWhat we believe
Strong opinions,
held accountable.
A demo that impresses in a meeting and falls over in the real world helps nobody. We build for the day after launch.
If a feature isn't worth building, we'll say so. If something breaks, you hear it from us first. Long relationships beat quick wins.
Your code, your data, your infrastructure. We document everything and never hold a project hostage.
We ship fast because we've built these systems before — not because we cut the corners you'll trip on later.
The empty state, the error message, the loading moment — quality lives in the parts most teams skip.
Authentication, tenant isolation, encrypted credentials and audited access come standard on everything we build.
Our proof
We use what
we build.
The strongest thing on our CV: Gochi, a complete managed-services platform we designed and engineered, now operating as its own company. When your development partner has shipped and scaled its own product, you're getting advice from experience — not theory.
