Public services · Software engineering · Mobile games

Useful software, built with care.

We build accessible public and community websites, solve complex software problems and develop mobile games of our own. More than thirty years of engineering experience, from government services to national retail and trading systems.

* Estimate: applying the recalled “roughly one third” share of equity trades to the London Stock Exchange’s reported £4.595 trillion domestic and international equity turnover in 2002 gives about £1.53 trillion. The one-third share is an informal recollection, so this is an annual-equivalent estimate rather than a contemporaneous measurement of orders submitted through the system. See the LSE’s historical statistics.

What we do

The work

Whole products

Someone has to own the architecture, write the code, wire up the pipeline and get the thing in front of users. We take that on end to end — and we are just as happy embedded in a team that already has momentum.

Public services

Experience on UK public-sector programmes through managed service providers and agencies. Accessible interfaces, practical publishing workflows and delivery within established assurance processes.

Rescue and modernisation

Established estates moved to the cloud while the business carries on running. One was an £11m system picked up years after the original team had moved on, and brought back into active development.

Mobile and games

A handheld for FedEx. A racing game that went to number one. An iOS puzzle game in development right now. Small screens have their own rules.

For community boards

Commissioning and building Pride in Place websites

Built for the work after launch

A website should make the board easier to run and the programme easier to follow.

Residents need clear ways to understand projects, take part and see what happened next. The board needs a publishing process it can sustain, with ownership and responsibilities settled from the start.

We bring long experience of public-facing government services. Our free guide covers ownership, accessibility, privacy, publishing and the questions to ask any website supplier.
