About The Founder

Hi, I’m Onur, founder of Marketized GmbH. 

I’ve worked in performance marketing for 10+ years and built Marketized with one goal:

  •  To turn marketing complexity into accountable growth.
 

Over the years I’ve managed €100M+ in ad spend and supported 120+ brands. Every project was different, but two patterns were constant:

  • Everyone wants to learn from the past and make better decisions next

  • Paid ads get more complex every year

What motivates me is turning that complexity into something clear and actionable—using data to guide decisions, creativity to bring ideas to life, and strategy to tie it together.

Marketized is for founders and teams who want measurable results, straight talk, and visible impact.

A short strategy session where we clarify your growth goals, current challenges, and success metrics. You leave with a clear picture of what we’ll audit—and why it matters.

Account Access

You grant secure, read-only access to your ad, analytics, and CRM data. This lets us ingest real performance signals while keeping full control in your hands.
