## What we do

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

- [AI & data](https://vigesimal.tech/service/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](https://vigesimal.tech/service/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.
- [Cloud optimisation](https://vigesimal.tech/service/cloud-optimisation): As you scale, cloud waste compounds. We audit what you run, cut what you do not need, right-size the rest.
- [DevOps & SRE consulting](https://vigesimal.tech/service/sre): CI/CD your team trusts, observability worth paging on, and infrastructure that holds at 3am.
- [Custom software development](https://vigesimal.tech/service/dev): Tailor-made web and mobile applications built around how your business actually works.

## How an engagement runs

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

1. **Discovery & consultation**: We learn the business, the systems, and what is actually blocking you.
   - Deep dive into goals and constraints
   - A clear read on what to fix first
2. **Design & development**: A sequenced roadmap, then working software in increments you can review, tested as it goes.
   - A plan with owners, dates and costs you can hold us to
   - Working software early, refined on your feedback
3. **Solution delivery**: Shipped to production on infrastructure that is monitored from day one.
   - Rehearsed releases with a rollback path
   - Handover your team can operate
4. **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.

## Partnerships

We build on the platforms our clients already trust.

- AWS Partner
- ClickHouse
- Coriolis

## Industries

Cloud, data and AI look the same on an architecture diagram and very different inside a bank, a retail network or a utility. These are the sectors we work in, and the problems we are usually brought in to solve.

- [Financial services & fintech](https://vigesimal.tech/industries#financial-services)
- [Retail & consumer goods](https://vigesimal.tech/industries#retail)
- [Energy & utilities](https://vigesimal.tech/industries#energy)

## Accelerator

The Vigesimal Accelerator helps early-stage startups build, scale and de-risk on the cloud. As an AWS Activate provider, we pair AWS cloud credits with hands-on engineering mentorship from years of building software, DevOps and SRE practices — so founders move faster on solid technical foundations.
