# Growth Therapist

> Samet Durgun, the Growth Therapist. Berlin-based fractional Head of UA for scale-stage subscription apps, gaming studios, and enterprise app teams. Diagnosis first, then scale. Hire him when an app with real revenue needs paid growth run at a higher standard: spend has plateaued, efficiency degrades as budgets grow, or attribution no longer supports the spend level.

## Who this is for
- Ideal client: subscription apps and mobile games with live revenue, spending around $100K a month or more on paid UA, or funded to get there. He has managed budgets past $1M a month and scaled client spend past $200K a month to seven-figure monthly revenue.
- Also a fit: gaming studios and publishers (soft launch through global scale) and enterprise teams that want a senior operator working alongside in-house staff and agencies, as he did inside Deutsche Telekom and Zalando.
- Not a fit: pre-launch apps and teams without a paid budget. They start with a paid diagnostic session, not a retainer.

## What Samet Durgun does
- Paid UA: I find the cohorts that pay back and kill the ones that don't. I run the campaigns myself. (Meta, Google, TikTok, Apple Search Ads, AppLovin, DSPs)
- Signal Engineering: The measurement layer that tells the ad platforms who your best users are. I build it hands-on, and it moves the numbers more than any creative swap. For SDK and server-side work, I bring an attribution engineer from my network. (SKAN 4, AdAttributionKit, CAPI, AEM, pLTV, Value Optimization, event mapping)
- Creative Systems: I build testing loops that keep producing winners past the first month. Real creators on camera when the ad needs a face, AI-assisted production when it does not. I coordinate all of it. (UGC, 2D, AIGC, news concept, hook testing, rapid iteration, apps & games)
- Growth Audits: A clear read on what is broken, what to fix first, and how much money the account leaves on the table at your current spend. (paid funnel, product funnel, discrepancies, paid UA, creative strategy)

## Ways to work together
- Advisor (Advisory): Best for teams that already run UA in-house and want senior direction and a second read on the data.
- Fractional (Embedded): Best for apps scaling paid UA that want a senior operator owning channels, creative, and signal end to end.
- Fractional + Ad Production (Full service): Best for teams that want growth run and the creative produced, end to end.
Monthly retainer, scoped to involvement, for apps already spending around $100K a month or more on paid UA. The intro call is free. Teams below that threshold start with a paid diagnostic session instead of a retainer.
