Microsoft cloud savings, delivered as a service.

Datafitters combines a continuous optimisation platform, a senior licensing advisory desk, and the FinOps execution to make the savings stick, so you don't just see waste, you book it. We've done this dozens of times, across mid- and large-cap companies worldwide.

What we do

Three services. One outcome: savings that show up on the invoice.

We run the optimisation cycle continuously across platform, advisors and execution. Pick one, or all three.

Platform · SaaS

Control Tower: the engine.

Continuous, read-only visibility into every M365 / D365 / Azure euro. Daily list of seats and resources to drop, downgrade or right-size. Drill from CFO total to a single user.

  • Daily refresh, with audit-grade history
  • Drill from CFO total to a single user
  • Evaluate and comment on each line item
Advisory

License Desk: the advisors.

Ex-Microsoft and ex-LSP licensing specialists who've negotiated >€100M of Microsoft contracts. We sit with you on renewals, true-ups, EA / CSP moves, and Copilot rollouts.

  • Renewal & true-up support
  • EA / CSP / direct guidance
  • Copilot rollout & ROI advice
Managed service

Results as a Service: the execution.

We run the optimisation cycle for you: surface findings, validate with your team, action the change, and prove the saving on the next Microsoft invoice.

  • Regular optimisation cycle
  • Flat fee, based on user count
  • Every saving proven on the invoice
About us

A small, senior team. We've sat on both sides of the Microsoft contract.

Datafitters is a focused team combining deep Microsoft licensing experience, hands-on data engineering, and a partner network. We built Control Tower because we kept watching organisations leave money on the table at every renewal cycle, and consulting alone couldn't keep up.

How we work

From first call to first invoice saving, in four steps.

From first connect to first action
We thought our M365 estate was already optimised. Datafitters found 1,840 unused seats in the first month, and an ongoing process to keep it that way without adding headcount.
