about

A consultancy that builds decision systems.

The commercial side knows what it wants but can't turn it into a system; the technical side builds systems but risks missing the commercial question. GDP brings both sides into one team. Our output is not a presentation, but the decision systems teams use every day.

Our principles

  1. 01 Decisions first, technology second. Tool choice is the last step.
  2. 02 A system in use, not a demo. The deliverable is the team's daily screen.
  3. 03 We don't promise outcomes we can't prove. Quality is shown by measurement.
  4. 04 Few tools, a clear architecture. Every extra tool is a maintenance burden.
  5. 05 We hand over knowledge. We leave capability, not dependency.

Let's talk.
