Two founders · one compact studio
Built on judgement, trust and a lot of software.
Daniel and Gary combine product leadership and architecture in one delivery loop, with capable models doing the mechanical work and evidence deciding when it is finished.
Why this exists
We wanted the freedom to build things properly.
Daniel and Gary worked together across regulated financial platforms before founding Zero Drift. They had already learned how each other thinks, where they disagree and whose judgement carries which kind of decision.
“So we don’t have to work for anyone else any more.”The founding brief
Gary McLean Hall
Former Head of Architecture at Hargreaves Lansdown. Gary leads system structure, technical boundaries and the independent challenge that stops confidence passing for proof.

How the studio works
People set the premise, make the consequential calls and own the claims. Models multiply the implementation effort. Mechanical gates test whether the result holds.
