We write everything down and hand over what we build.

What we kept seeing

Many organisations buy software that arrives late, comes without documentation, and is supported by a vendor who is hard to reach once the contract ends. Staff work around the system instead of with it, and the next upgrade starts from scratch.

A different way to work

Sonestack was set up to work the other way: a team that writes everything down, hands over what it builds, and offers support for as long as a client wants it. We cover the full stack, from the servers and networks underneath to the applications, data and training on top, so one accountable team answers for the whole system.

Where the name comes from

Every system is a stack of layers, from the hardware to the screens people use, and a fault in one layer reaches every layer above it. The name is a reminder to build every layer properly.

Where we are going

Our mission

Dependable systems that organisations own.

We plan, build and integrate software, data platforms and cloud infrastructure around the way our clients already work, then hand over the code, accounts and documentation so they stay in control.

Our vision

The partner organisations trust with their core systems.

We want to be the first call when a government agency or business needs a system that has to work every day, because our past projects were delivered as agreed and documented in full.

Five values we work by

These shape how we plan, build and report on every project.

  • Write it down

    Decisions, designs and handovers are documented as we go, so nothing depends on one person remembering it.

  • Say it plainly

    We give honest estimates and clear updates, including news a client would rather not hear. You always know where your project stands.

  • Answer for the whole system

    One team is accountable from the servers to the screens, so problems get fixed instead of passed between vendors.

  • Build for the people who use it

    We design around how staff actually work and test with them before anything goes live.

  • Secure from the first design

    Access control, audit trails and data protection are part of the plan from the start, never added at the end.

The tools we build with

We pick tools for reliability and long term maintenance, and adjust the set to fit each project rather than forcing every project into one set.
