Why Not a Big Consultancy?

We’ve all worked at large integrators. We know the playbook.

Big Firm

  • Senior architect leads the kickoff
  • Project is handed to juniors
  • PM manages from a distance
  • Your budget trains their people
  • The invoice doesn’t change

DWHPro

  • Senior engineer sells and delivers
  • Same expert from day one to go-live
  • 1–2 projects at a time — full focus
  • No learning curves on your budget
  • One invoice, one accountable team

Our Goal

  • Build it right the first time
  • Your team understands the system
  • Full documentation & handover
  • You run it without us
  • That’s when we’ve done our job

Our Services

Vendor-Neutral Assessment

Know exactly what to do before spending a single euro on migration.
