Testclub was founded in 2012, on 25 years of testing software where getting it wrong is expensive. Trading platforms, insurance, energy, government.
That work taught us where defects come from. Not bad code, but things nobody specified. The same gap that lets a bug through lets an attacker through.
That is why we test functionality and security of APIs and AI integrations now. It is the same work, but its importance has multiplied.

LinkedIn →Evidence over assertion. Every claim reproducible, every finding shown with impact.
Specification thinking. Asking questions the team may not have asked.
Understand, Map, Test, Report. Conclusions follow from evidence, never precede it.
This way of working has a longer argument behind it: why specification gaps are where bugs, breaches and AI failures live, and why the skill of finding them transfers.
Read our philosophy: Mind the gap →Before security, Testclub spent years building and repairing QA practices for clients including Schroders, EDF Energy, esure, Nephila Capital, Nando's and Sportingtech, including a full QA transformation at Sportingtech. That heritage is why the security work reads unfamiliar systems quickly: we've spent two decades learning how teams actually specify, build and break things.
