OUR TEAM

Named senior accountability on every engagement.

A senior lead remains accountable from diagnosis through verification, supported by specialists using Onyx's documented delivery system.

FOUNDER & CEO

Leon Gordon

I started in data before 'data strategy' was a job title. Fifteen years ago, I was the person in the room explaining to executives why their numbers didn't add up, and building the systems that fixed it. That hasn't changed. What's changed is the scale.

I founded Onyx Data with a conviction that most consultancies get the sequence wrong: they build first and govern later. We reverse it. Governance first, outcomes before pipelines, measured like a product. That methodology supports governed delivery across sectors including maritime operations and financial reporting.

I write for Forbes because I believe the people making AI decisions at board level deserve honest frameworks, not hype. I study at Oxford because I believe governance should be informed by academic rigour rather than vendor marketing. And I built FabOps because I got tired of seeing the same governance gaps in every Fabric deployment I walked into.

When you book a strategy call with Onyx, you're talking to me or one of our senior leads, not a sales team. We'll be honest about whether we can help, and if we can't, we'll tell you.

Founder-Led Strategy

Every engagement starts with Leon or a senior lead. We scope the work, define the outcomes, and own the methodology. You never explain your problem twice to a rotating cast of account managers.

COMMUNITY

We Don't Just Deliver Fabric. We Shape It.

Before we were a consultancy, we were a community. Onyx founded the Microsoft Fabric UK User Group and runs the DataDNA Data Visualisation Challenge, where data professionals share practical work and learn from one another.

This is part of Onyx’s channel and authority moat: it keeps the team close to emerging Fabric questions, implementation patterns and practitioner feedback.

We've been able to reduce the latency on the data we act on from minutes to seconds, all without increasing the number of people involved in providing support to our customers.

We achieved exactly what needed to be achieved, it was a full success. The team at Onyx knows how to engineer solutions, whilst many consultancies only know theoretically.
