Case Study · Supplements

Subscription attach: 8% → 47%. LTV up 3.2x in 6 months.

Nutrition & Supplements Brand · 6 months

Business Overview

Supplements brand doing ₹80L/month. Repeat purchase was manual — people had to remember to reorder. Every acquisition needed to earn back CAC in one order.

Problem

The category is inherently repeat-driven, but the funnel was one-time. Founders were scaling ads to compensate for a broken retention engine.

Diagnosis

Zero subscription flow. 12% M2 repeat. No replenishment logic. LTV / CAC of 1.2x — barely profitable.

  • 01Subscription-first funnel
  • 02Replenishment reminders (email + WhatsApp)
  • 03Bundle-based upsells at checkout
  • 04Loyalty tiers for annual buyers
  • 05Founder education content flywheel

Execution

  • M1–2: Subscription product setup, PDP redesign
  • M3–4: Retention flows, WhatsApp broadcast
  • M5–6: Loyalty tiers + community launch
