Case Study — 01

Premium Business Coach — Funnel Engineering & Vertical Scale

High-ticket coaching · Google Ads · VSL Funnel

A high-ticket business coach needed to scale their pipeline from cold traffic while hitting strict profitability benchmarks. The existing funnel had a 10% opt-in rate and was routing unqualified calls into the sales team.

We restructured the entire acquisition funnel around the VSL, repositioned it as a premium "Free Training," and built friction into the booking flow to filter intent.

01

Positioning Pivot

Eliminated low-intent lead magnets. Repositioned VSL as exclusive "Free Training" — lifting landing page opt-in rate from 10% → 40% (4× uplift).

02

Strategic Friction

Delayed "Book a Call" CTA to the 20-minute mark of a 30-min video. Reduced unqualified call rate to under 2%.

03

Vertical Scale

Deployed Google Ads vertical scale framework: boosted weekly budgets by 5× target CPQ every 7 days without disrupting optimization.

Case Study — 02

Classical Music Streaming App — User Acquisition Efficiency

Mobile App · Meta Ads · Google Ads · Subscription Model

A niche classical music streaming app launching at $10/month — higher than Spotify — with near-zero brand awareness. Initial setup had a 1-month free trial and an 85% post-trial churn rate.

Through iterative offer testing, we identified a $1 introductory month model that fundamentally changed retention economics. Churn halved. Average subscriber lifecycle stretched to 10 months.

The $30 CPA target was not achieved — but context matters. Benchmarked against in-house teams at Deezer ($100 CPA, ~20 specialists) and Qobuz ($200 CPA, ~20 specialists), this campaign — run largely solo — outperformed both by 1.6× to 3.3× on capital efficiency.

Result

1,838 website purchases at $71.89 CPA · $132,129 Meta spend · Churn reduced 85% → 40% · 10-month avg subscriber lifecycle · Beat Deezer & Qobuz in-house teams on efficiency.

Esensa d.o.o — E-Commerce Webshop Launch & Meta Ads

E-Commerce · Pharmacy & Wellness · Meta Ads · CRO

A pharmacy and wellness brand launching their first dedicated e-commerce webshop at 1% CVR — a level that made paid acquisition economically unviable. Multiple agencies had attempted to make Meta Ads work before this engagement. None succeeded.

I led the full webshop build project — coordinating the client and external dev agency — with every element (product pages, checkout flow, trust signals, copy hierarchy, mobile UX) optimized for conversion from day one.

Meta Ads were rebuilt with a clean-slate structure: new campaign architecture, refined audience segmentation, and creative developed to match brand tone while driving purchase intent directly.

Stefan played a pivotal role in the creation and optimisation of our online store, which resulted in a significant increase in our sales conversion rate — from 1% to 2.4%. He managed our Meta Ads account, turning it into a profitable channel which was impossible for several agencies before him.
