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.

Co-founder

Mesut Gültepe

A background in banking and management consulting; data science, technical architecture, analytics systems, CRM and risk management. Owns the data model and technical architecture on projects.

Co-founder

Mutlu Gültepe

15+ years of FMCG commercial and marketing leadership: pricing, channel management, customer growth, management reporting, financial management. Owns the commercial question and business value on projects.

One owns the commercial question, the other the technical architecture; every project advances with both perspectives at once.

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.

A 30-minute intro call. No sales deck: we listen to how your data and decisions work today, and share a clear first read on where to start.
