AI & data

Put your data to work.

We build the pipelines, warehouse and reporting that make your data dependable, then the agents, assistants and models that act on it, run like any other production system.

Where we do our best work.

Most engagements start with one and grow. The same senior engineers stay on your account throughout.

In production, not in a deck

AI & data

The pipelines, warehouse and reporting that make your data dependable, and the agents, assistants and forecasting models that put it to work, with evaluation and a person in the loop wherever a wrong move is expensive.

Migration & modernisation

Legacy systems rarely fail all at once; they get slower, riskier and more expensive to change. We move them to modern architecture in rehearsed waves, each small enough to reverse.

How an engagement actually runs.

Four phases, no black boxes. You see the roadmap and the numbers before anyone writes code.

Continuous improvement

We stay on to tune, support and extend what we built.

Ongoing monitoring and optimisation
We stay on call for what we built
Why Vigesimal

A team of problem-solvers, not a body shop.

We would rather tell you what not to build than bill you for it. In practice that means honest estimates, small senior teams, and systems we are willing to be on call for.

Honest estimates
If a piece of work is not worth doing, we say so before you pay for it.
Senior by default
The engineers who scope your project are the ones who build it.
Small increments
Working software early and often, so a wrong turn costs days, not months.
We run what we build
We stay on call for our systems, which keeps us honest about how we build them.
