Senior Practitioners. Real Outcomes.
We are a specialist consultancy of senior data and AI practitioners — no juniors, no hand-holding, just experienced teams that deliver.
We partner with ambitious organisations to turn data into their most valuable asset. Every engagement is led by senior practitioners — no juniors, no handoffs, no learning curves charged to your project.
Our Values
Outcomes Over Activity
We measure success by the impact we create — not the hours we log or the diagrams we draw. Every recommendation is tied to a measurable business outcome.
Senior-Only Delivery
Every Extrodata practitioner has 10+ years of hands-on experience. You get seasoned experts from day one, with the judgment to navigate complexity and the skills to deliver.
End-to-End Capability
From strategy through architecture to implementation — we don't hand off between phases. One team owns the outcome from start to finish.
Partnership, Not Vendorship
We embed with your teams, adopt your ways of working, and leave you stronger than we found you. Knowledge transfer isn't an add-on — it's the point.

Strategic Partnerships
&
Extrodata maintains active working relationships with Microsoft and Snowflake. This means our clients receive platform guidance informed by direct vendor engagement, not just public documentation.
How We Start an Engagement
Every partnership begins with clarity — not assumptions.
Structured Discovery
A time-limited, fixed-scope assessment that produces a clear picture of your current data estate — platforms, pipelines, people, and processes.
Gap Analysis & Prioritisation
We identify the gaps that matter most and rank them by business impact, not technical novelty. Every finding ties to a measurable outcome.
Roadmap & Business Cases
A prioritised roadmap with quantified business cases for each initiative — so leadership can invest with confidence and teams know exactly what to build first.
Proof of Concept
Where appropriate, we deliver a working proof of concept alongside the assessment — de-risking the investment and demonstrating value before full-scale delivery.
How We Work
Agile Delivery
Data and AI programmes fail most often at the delivery layer. Our principals hold formal Scrum certifications (PSM1) and apply agile delivery discipline to every engagement — with sprint-based planning and clear definitions of done for data products.
Global Scale
Our principals have led delivery across globally distributed teams. For enterprise clients running multi-region data platforms — including cross-region data sharing across UK, Singapore, and US environments — we design and operate with global scale in mind.
