Syntax — a seasoned team, ten years and millions of dollars of investment, accelerated by AI agents

01 / 05The chaos

Every great system begins as chaos.

Spreadsheets, inboxes, twelve tools taped together. This is where our clients find us.

02 / 05The atelier

We fold it into order.

AI agents do the heavy lifting. Senior engineers, prompt engineers and QA direct, review and guarantee every line.

03 / 05The build

Built by agents. Approved by people.

Agents fold the interfaces together, piece by piece. Senior engineers and QA inspect every one before it ships.

04 / 05The systems

Enterprise systems, beautiful interfaces.

ERP, platforms and automation for corporates and public bodies.

01 — The story

Not a shortcut.
An investment.

A working prototype within the week comes from ten years, millions of dollars and senior people, not from AI alone. AI lets us do more, check more and ship more safely.

01 The first decade

Software people can’t
afford to get wrong.

Mortgage platforms and UK lenders. HR. A medical consultancy. Property. Conservation data. In every one: an audit trail, a rollback plan and a person’s name against every change.

02 Our own bets

Products we started
ourselves.

Xinecto was founded and built by our own team: idea, launched product, investment and eventually a buy-out. ClosingBench is a Syntax company. Our ROI dashboard we built for ourselves first.

    A CRM for the private sector, built from wireframes to end product.

    Built for ourselves first

    Automated data collection that proves whether automation is paying off.

03 The investment

The week is built
on a decade.

We have spent about ten years, and millions of dollars, building our own systems and AI engines: everything that makes a build quick, a screen beautiful and a release safe. That investment, plus the senior people who direct it, is what puts a working prototype in your hands within the week.

04 The turn

Review replaced
typing.

When agents got good enough to write real code, we kept the senior engineers and put agents underneath them, then rebuilt delivery around review rather than typing. It is still a great deal of senior work. What changed is how much of it we can do, how much we can check, and how much safer we can make what we ship.

The rule

A release doesn’t go out until a named senior engineer has approved it.

That isn’t a policy on a page — it’s a step in the pipeline that can’t be skipped.
