We build software you own.

Syntelic is a UK software firm, born in AI. We specialise in building systems that reflect how you actually work, and we put AI inside them, accountably, in production: systems that run businesses.

Four founders, nearly a century of SME and enterprise IT operations, development and leadership between us.

Four things, done properly.

Subscription replacement

You're paying five or six figures a year for software that almost fits. We analyse your current system; the business inputs/outputs, workflows and integrations, and build the system you would have chosen. Your data, your solution, your roadmap.

We have proven capability to create applications that precisely map existing functionality by analysing your existing platforms. Sometimes from raw browser traffic, sometimes from exports and sheets. We've mirrored hundreds of gigabytes of records with independent cross-checks on every count, and kept the mirror in sync while the replacement was built alongside it. It's exactly as tedious as it sounds, and it works.

Custom automation & applied AI

Consultation audio that becomes a clinical letter. A work queue that triages itself. An assistant that operates your system with the same permissions and audit trail as a member of staff. We build AI into working software, with approval steps before anything is sent and every action logged and attributable.

AI in production is an engineering discipline. We treat it as one.

Product engineering

Complete products: API, web portal, native iOS. A senior team, test-driven, deliberately few dependencies. Boring in the ways that matter, so the software is still maintainable in year five. Our own platform, Praxo, is the standing proof that we ship.

AI security & governance

Adopting AI across an organisation without losing control of it. We help businesses get visibility of every AI tool in use, set intent-aware policies against prompt injection and data leakage, and govern AI agents as well as the people using them.

A note from the four of us

We started Syntelic because we kept watching good businesses rent software that almost fit, and pay for the gap every day in fees, in workarounds, and in data they couldn't take with them.

Between the four of us there is almost a century of IT across small business, SME and enterprise. We've bought these systems as CIOs, supplied them as vendors, and written them line by line. We decided the next ones we built would be systems our clients own.

The rest follows from one observation: the organisations with the most to gain from AI are often the ones least able to survive getting it wrong. A large enterprise can absorb a failed programme. A fifty-person firm can't.

So we put infrastructure before interfaces, and evidence before estimates. Most of the problems we are called in to fix trace back to a tool bought before anyone asked what it would stand on.

We hold no reseller agreements and no platform allegiances. There are no licences in our model to defend, so our advice on any technology stays the same whether or not you act on it. You keep your own data, your own credentials and your own way out.

And we build with client teams, not around them. A good engagement leaves the people who own the system able to run it without us, and glad to keep us on all the same.

Praxo. Practice management for the AI era.

The platform we build, run and stand behind, for general practice, dental and other appointment-based clinics.

Everything connected

Records, diary, clinical notes, billing and communications in a single system. It sounds obvious. It's surprisingly rare.

Click or Tell.

A full visual interface, and an assistant that does the same work from a sentence: "Book Mr Johnson with Dr Khan next Tuesday at 2pm." Ten clicks become ten words.

Audited by design

Every action logged, AI-assisted actions flagged as such, approval before anything leaves the building. GDPR and NHS DSPT aligned, UK data residency.

Recorded in the live app: the assistant briefs the afternoon, then cancels an appointment. Reason requested, approval required, action logged. Demo practice data.

A senior team with delivery scars.

The four of us, and three principles we won't trade away, whoever the client is.

Tony, founder

Tony

Thirty years in the technology industry, from enterprise networking to fractional technology leadership.

Rich, founder

Rich

Thirty years on the commercial side of SME and enterprise IT. If you have ever bought from a vendor, he was on the other side of that table.

Warwick, founder

Warwick

Thirty years as a technical leader, in CIO and CTO roles, buying and running systems of exactly the kind we now build. Chartered Fellow of the British Computer Society.

Dominik, founder

Dominik

More than a decade across UX research, software and cloud engineering, in finance, media and healthcare.

For what it's worth, our coverage: enterprise architecture, networking across internet, WAN and LAN, and cloud architecture. We've worked with micro-businesses, start-ups, scale-ups and established firms, in more sectors than we can list without showing off.

We show our working

Everything on this site is a real system you can be shown: record counts, test suites, audit trails. If we can't demonstrate it, we don't claim it.

Boring is a feature

Few dependencies, test-driven, readable code, standard tools. The exciting part should be what the software does for your business.

Regulated-by-default

Our systems run in UK healthcare: encrypted records, role-based access, break-glass controls, full audit. We build to that standard even when nobody makes us.

Tell us what your software costs you.

We'll tell you what it would take to own it, and we'll be honest if the answer is "keep what you have". A real conversation with one of the four people who would do the work.
