Samet Durgun is a fractional Head of UA for scaling subscription apps and mobile games, working from Berlin with teams globally. He runs paid acquisition hands-on: Meta, Google, Apple Search Ads, and TikTok, the signal engineering underneath (SKAN, CAPI, pLTV, value optimization), and creative testing systems that keep producing winners past the first month.

His talks are data studies from real accounts rather than frameworks: a $383K country-by-country audit of Meta's tROAS algorithm, a $606K test of what actually predicts day-28 ROAS, and the reconciliation logic for when Meta, the MMP, and the subscription platform disagree. Client spend has scaled past $200K a month to seven-figure monthly revenue; at Wooga he managed $1M+ a month in UA budgets, with earlier roles at Zalando, Deutsche Telekom, Google, Intel, and Oracle.

He publishes every study at growththerapist.com/blog, writes the Profitable App Growth newsletter, judged the App Growth Awards in 2024, and holds a 5.0 on Clutch. He presents in English, Turkish, and German.
