About x·maze it

Founded in 1999 as an independent technology consultancy, x·maze it has spent a quarter of a century doing one thing: applying the right technology to each problem — honestly, and by hand.

Nicholas Tosis, Platform Engineer

Nicholas founded x·maze it in October 1999. Since then he has designed, built and run infrastructure for organisations of every size — from a two-person art consultancy in Mayfair to petascale genomic systems for the NHS. That's 25 years of shipped, running systems, not slideware.

The work spans the full spectrum: telephony systems and centralised backup, DNS and mail platforms, firewalls and security policies, cloud migration and Kubernetes — always built with open standards, and always to fit the client rather than the other way around.

How we work

The principles that guide every project

These aren't marketing slogans — they've been the foundation of x·maze it since 1999.

What works, not what sells

Technology should be about solving your problem — not the most popular or most-marketed option. We give impartial advice, unbiased by hype.

Open standards

Openness means flexibility. We build on open standards so you're never locked into a single manufacturer, and your systems can evolve with you.

Honest, always

We won't rip you off, and we won't hesitate to say if your current solution is wrong — even if it means recommending against our own sale.

We do it right, or not at all

We don't compromise on principles to win or keep a client. That gives you confidence in the integrity of our advice.

Long-term relationships

By understanding your business deeply, we can help you adapt as your needs change — a partnership, not a transaction.

Technology as a craft

This is a vocation, not just a job. The result is more effective, more considered work — for you.

Why now: the AI advantage

Twenty-five years of building infrastructure by hand gives us something most consultancies can't offer — a platform engineer who has seen it all. What's changed is that the day-to-day running of those systems can now be automated and watched over by an AI partner.

That means our clients get the depth of a senior engineer combined with the constant attention of a tireless assistant: monitoring, maintenance, answering the phone, flagging problems early. It's the difference between IT that needs managing and IT that manages itself — so you can get back to running your business.
