About CodexSigma
We build the hard technology behind ambitious companies.
CodexSigma is a technology company spanning software, AI, robotics, semiconductors, and space. We work on systems where failure is not an option — payroll that files with HMRC, robots that run factory lines, satellites that keep supply chains moving.
We believe in ownership over hand-offs. Small, senior teams stay with a project from first sketch to production. Everything we ship is self-hostable and your data stays yours.
Our flagship product, QW Payroll & ERP, is the AI-powered payroll and ERP platform for the UK — multi-tenant, HMRC RTI ready, and built to run on your own servers.
