The supplement brand LTV agency

Your CAC keeps climbing.
Your LTV hasn't moved.
We fix that.

We build retention systems that compress your CAC payback window — so the customers you're already acquiring become profitable, predictable, and worth scaling.

Sound Familiar?

Most supplement founders we talk to have the same conversation on repeat.

  • D30 repurchase rate under 15% — most of your CAC never pays back

  • CAC payback window stretching past 60 days

  • Klaviyo installed, flows half-built, campaigns sent when someone remembers

  • Post-purchase experience that doesn't drive habit or reorder

  • Retention deprioritised every week because acquisition always feels more urgent

The 14-day sprint, step by step.

1. Diagnose the Gap

We map your retention gaps against your current revenue — and benchmark what fixing them is actually worth.

2. Rebuild the Foundation

We rebuild the sequences that drive repurchase, habit formation, and payback speed — built specifically for how supplement customers buy again.

3. Implement + Integrate

Every flow is connected, tested, and built for scale. No noise. No patchwork. No guessing.

4. Test + Ship

We test every flow against your baseline before handing over a fully documented, ready-to-scale retention system. Clean build. No loose ends.

Fixed scope. Fixed fee.
Done in 14 days.

Stop Losing Customers After the First Order.
