What clients say

What clients say about working with me, Samet Durgun. Every quote below is from a named person at a named company, posted on my LinkedIn profile or on Clutch and linked to it, and the two ratings link to the platforms that hold them. Clutch rates client work, GrowthMentor rates mentoring. I did not edit the quotes.

This page is for the moment right before booking a call. A verified client rating and a mentoring rating you can check, and six clients you can look up. The results the quotes refer to are in the case studies: Videa’s D0 ROAS from 20% to a 43% record week, EatBetter’s $10K to $180K MRR in two months and Horse Racing Solitaire’s D0 ROAS doubled over two years.

Before the full quotes, the table shows who each one is from, what I did for them and the result behind it. A result with its own case study links to it; a result that only appears in the quote is marked “per the client”.

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.

Anıl Sözeri · Cofounder, Mellon · LinkedIn

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.

Brad Grievson · COO & Cofounder, Salto · LinkedIn

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.

Stefanie Graser · General Manager, ShopBack · Clutch

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.

Alasdair McMaster · Cofounder, Honig Games · LinkedIn

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.

Callan Saurma-Jeltsch · Marketing Director, Social Synergize · LinkedIn

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.
