More than just software delivery

We’re a software consultancy with a difference. We work with hi-tech businesses who have a technical team, or who aspire to a technical team, help them continuously deliver software, encourage excellence in their engineering and ultimately make sure they are self reliant. Think of us as software engineering player-coaches.

We provide experienced specialists in all the major software engineering disciplines – people that have learned lessons from fast moving startups and globally-recognised enterprises.

Strategic Partners

Our favoured way of working is as a technical delivery partner. We are at our most effective building or augmenting an in-house technical team. We do not view ourselves as outsourcers – our objective is to foster and encourage technical excellence and self-sufficiency in our clients, not to maximise consultants. We are a part of your team.

Multi-Disciplinary Expertise

We’ve set up startups from scratch, delivered petabyte scale data insights for governments, architected and managed cloud infrastructure and delivered production software in industries ranging from medical robotics to fintech. It’s difficult to surprise us.

Accessible Technology

We’re committed to ensuring professional technology solutions are accessible to all businesses, laying foundations to help you become self-sufficient to evolve.
