Was Kunden sagen

I worked closely with Samet while he led the paid marketing transformation at our company, and the impact was substantial and lasting. We built our marketing function from the ground up together: the team, the processes, the way we think about growth. Together we caught a viral moment that helped carry us to seven-figure monthly revenue. If you are looking to build or scale a serious paid marketing engine, Samet is someone I would recommend without hesitation.

We've worked closely with Growth Therapist, led by Samet, for the past two years as we scaled our first product. He led creative and UA strategy through our soft launch and beyond, and consistently drove fast, high-quality creative experimentation. He's proactive, communicative, and very transparent.

We were spending a six-figure monthly ad budget on Jukebox and could not clearly see whether the money was coming back. In the two months we worked with Samet the campaigns were rebuilt by market and platform, and for the first time we could see which country and which campaign paid its money back.

In numbers: Meta reported a purchase ROAS of 0.32 in the four weeks before the new structure and 0.55 in the four weeks after, with 13% less spend. In Adjust, day-0 ROAS on the main campaigns went from 0.25 to 0.46. Part of that came from our own product work, we pushed the annual plan harder in the same period. Samet helped us read the two together, so we could tell what came from the campaigns and what came from the paywall.

He is someone I trust. He has always been the first person we call.

His expertise in performance marketing and content optimization was invaluable. A structured approach, deep technical knowledge, and actionable results delivered fast. What impressed us most was the speed at which he delivered.

Samet helped us find UA cohorts that hit 100% ROAS by D28 in our key market, the US. He spotted indicators in our data that let us push to Tier 1 markets faster and saved us significant spend. The creatives he ran resonated perfectly with our audience.

Incredibly helpful, professional, and to the highest knowledge in all things paid media. He helped my team thrive in creating ads and testing creatives, and on each campaign he exceeded our clients’ expectations.

Samet stepped in and gave us the confidence boost we needed. It was a turnkey solution: an assessment call, access to our tools, and he handled the rest. Within a short time, and very little ad spend, we had several experiments completed and a solid read on our starting CPI.
