Lowering Fitness-App CAC with AI Creator Volume
An illustrative scenario: how more creative volume attacks a rising-CAC problem.
This is a representative scenario based on UMG's approach — not a specific client account. The setup: a growth-stage fitness app hitting a creative-fatigue ceiling on Meta and TikTok, with CAC climbing month-over-month despite steady spend. Here's how we'd attack it.
What's included
- AI creator engine
- 10–20+ concepts/month
- 3-5 hook variants per concept
- Sustained refresh cadence
- Attacks creative fatigue
The diagnosis
Creative test volume is usually the bottleneck. A few net-new concepts per month isn't enough to outpace fatigue at meaningful spend levels.
The intervention
We'd launch an AI fitness creator and stand up a content engine producing 10–20+ net-new concepts per month, plus 3–5 hook variations per concept for testing.
What success looks like
A meaningful reduction in CAC, more install volume on the same media budget, and a creative refresh cadence sustained for months without dropoff.
