Before / after
Most reporting we inherit lives in versioned spreadsheets: three revenue columns, broken lookups, and a figure that changes depending on who exported it. We replace that with one governed model and dashboards that refresh themselves.

Services
From legacy data replication to dbt transformation, reporting and bespoke software—delivered by senior practitioners who hand the platform back to your team.
REPLICATION
Move data reliably from anywhere—including legacy and on-premise systems—into your modern platform, with minimal downtime.
TRANSFORMATION
Model and transform your data with dbt, the modern standard for analytics engineering. We maintain existing SSIS/SSRS/SSAS estates and modernise where it pays off.
ENABLEMENT
We embed with your in-house software team so they own and support the platform long after our engagement ends.
PERFORMANCE
Squeeze more out of what you already run—faster queries, lower latency, and healthier, more reliable pipelines.
COST
Reduce spend without reducing capability—right-sized infrastructure and smarter usage of what you already pay for.
TRAINING
Often you don't need new tools or infrastructure—you need to use what you have to its full advantage. We train your team and optimise current systems.
REPORTING
Turn modelled data into dashboards and reports people actually use to make decisions.
SOFTWARE
When off-the-shelf doesn't fit, we build tailored software that slots cleanly into your data estate.
Method
No endless discovery—just pragmatic progress, with a deliverable at the end of each phase.
We immerse in your data landscape—systems, processes, people, and pain points. Our assessment delivers a clear maturity baseline and opportunity map.
Co-create a target architecture and phased roadmap. We balance quick wins with strategic foundations, ensuring every increment delivers measurable value.
Engineer production-grade systems with DataOps rigour. We implement in vertical slices, automating testing, deployment, and observability from day one.
Transfer knowledge and establish operating models. We upskill your teams, define SLAs, and create a continuous improvement cycle for your data platform.
Contact
No sales pressure—just a frank discussion about your challenges and how we might help. We typically respond within four hours.
