James Walker speaking on stage

About

Engineer, ex-CEO, researcher.

I've spent the last decade building software businesses from scratch — first as a founding engineer at a company that was later acquired, then as the founder and CEO of my own, bootstrapped without venture capital. Now I build my own products, and talk and write about what I learned building the others. Hands-on most days.

The journey

Research-grade depth, founder-grade discipline.

The willingness to be in the codebase and in the strategic conversation in the same week — and the experience to know which one a given problem actually needs.

  1. Now

    Avoxy Technologies

    Founder

    Founding engineer and CTO for OneHundred and OnceHeld — both seed-funded on the strength of the build, both in live use; clients have raised over £5M to date. These days the building is my own products, and I'm not taking on new engagements.

  2. 2017 – 2025

    Curiosity Software

    Co-founder & CEO

    Bootstrapped, no venture capital, three co-founders in a room. Grew to an international team serving enterprise clients across financial services, technology, and consulting. Learned — at some cost — what to build first and what to let wait until there were real users and real revenue.

  3. Ongoing

    Recyclr

    Non-exec director & engineer

    Waste management tech — built for the UK's 2026 mandate.

  4. Early career

    Grid-Tools Ltd

    Early engineer

    Came up as an engineer at a software company later acquired by CA Technologies. My PhD in machine learning at Swansea sat behind the technical work the whole way through.
