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 has now delivered £93M in documented revenue growth across seven major enterprise engagements — from maritime satellite operations to global 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, not just 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.
OUR MODEL
Built for Depth, Not for Headcount
We don't carry a bench of juniors waiting for projects. We curate teams of Microsoft-certified specialists matched to your specific challenge — led by the people who designed the methodology.
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.
100% of strategy calls led by a Microsoft MVPCurated Expert Teams
For each engagement, we assemble a team of Microsoft-certified specialists matched to your technology stack, industry, and governance requirements. Senior practitioners, not graduates learning on your time.
60+ Microsoft-certified consultants across 6 disciplinesCommunity-Backed Knowledge
As founders of the Microsoft Fabric UK User Group (15,000+ members) and the DataDNA community (28,000+), we don't just deliver Fabric — we shape the conversation around it. Our team stays at the frontier because we help define it.

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 — now 15,000+ members and the largest Fabric community in the UK. We run the DataDNA Data Visualisation Challenge with 28,000+ members, where data professionals from around the world showcase their skills every month.
This isn't a side project. It's how we stay at the frontier. When Microsoft ships a new Fabric feature, our community is testing it within days. When governance patterns emerge, we see them across thousands of practitioners before they reach the documentation.
What It's Like to Work With Us
Not just what we delivered — how it felt.
JG★ MICROSOFT CUSTOMER STORYWe'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.
DMWe 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.
RRWorking with Onyx Data has been an absolute pleasure. We highly recommend Onyx Data to any organisation needing data analysis and training services.
We're Always Looking for Exceptional People
Onyx works with a curated network of Microsoft-certified specialists. If you hold senior Azure, Fabric, or AI certifications and want to deliver governance-first engagements with enterprise clients, we'd like to hear from you.
