What we do

I

Technical leadership

Part-time CTO and architecture support for growing software businesses, from platform decisions to AI-assisted delivery.

II

Software development

Complex problems solved with straightforward, maintainable code. Experience across public sector, financial services and high-volume platforms.

III

Small business innovation

From a first website to a funded prototype, we help entrepreneurs make their ideas tangible.

Fractional technical leadership

Technical leadership, without the full-time hire

Many growing software businesses need the decisions a CTO makes well before they can justify hiring one. We provide part-time technical leadership, typically a few days a month, focused on the choices that shape how quickly and safely a team can deliver.

Platform

Modernisation and ownership

Taking control of infrastructure from outgoing suppliers, and modernising legacy technology that is slowing delivery.

Team

Structure and delivery

Right-sizing the team, from outsourced consultancies to lean contract developers, with practices that suit your context.

Security

Assurance and remediation

Commissioning external penetration testing and working through the findings, so security keeps pace with growth.

AI

AI-assisted delivery

Introducing AI-assisted development in a considered way, helping developers use it well and ship features faster.

We take on a very small number of these engagements at a time.

Software development

Built to last, not to impress

We write software that solves real business problems. Our engineering is grounded in three values that we've held since day one.

  • Success. If you succeed, we succeed. We align our work to your outcomes, not billable hours.
  • Simplicity. We write software that is easy to understand, maintain, and support.
  • Stability. We choose the right technology for the job, not whatever is trending.

Small business innovation

You don't have to be big to build something brilliant

Individual mentoring

For sole traders and small teams. We coach you to build simple solutions yourself, from a single-page site to your first Shopify store, and leave you with the tools to maintain them independently.

A couple of days

Idea prototyping

We love turning ideas on paper into something potential customers and investors can actually experience. A prototype is the fastest way to learn whether your idea works in the world.

A couple of weeks

Bespoke solutions

For businesses ready to build production systems. We work with you to architect and deliver a solution that scales. We're open to discussing equity arrangements in the right circumstances.
