About
Depth without unnecessary complexity.
Divide by Zero is an independent mathematics and technology consultancy, based in the UK and working internationally.
Our perspective
Good technical work makes the difficult clear—and the clear useful.
Built on experience.
Our work draws on more than 20 years across quantitative finance, mathematical modelling, technology and digital product development.
That experience includes founding and growing four product studios, building international teams of more than 100 people, and completing two successful acquisitions. It brings a practical understanding of what must happen after the model is complete or the architecture is drawn.
We combine first-principles thinking with commercial judgement. Recommendations are independent, direct and shaped around the problem—not a preferred technology, framework or predetermined answer.
How we work
A small set of principles.
Start with the real question
We define the decision and its constraints before reaching for methods or technology.
Make reasoning visible
Assumptions, trade-offs and uncertainty are explained clearly enough to challenge.
Design for use
Our work must survive contact with customers, teams, systems and commercial reality.
