Subscriptions built around the protocol, not one product.

Supplement brands retain best when they sell a routine, not a single SKU. Gro ships multi-product stacks together, swaps items on a schedule, and keeps the whole regimen on one plan. Every feature included, one simple fee.

Visual placeholder Protocol in the portal: the current stack and the phase it moves to next month.

What it solves.

Single-product subscriptions churn fast.

Bundle a protocol into one subscription so customers commit to a routine, not a jar. Higher order value, stickier retention.

Regimens change from month to month.

Schedule swaps so the stack evolves. Loading phase in month one, maintenance from month two, automatically.

Refills arrive at the wrong time.

Replenishment timing matches how fast each product is actually used, so nobody doubles up or runs dry.

The stack that evolves on schedule.

Map out the phases of a protocol once and Gro moves each customer through them automatically, swapping products in and out at the right cycle. It reads like a plan from a practitioner, not a shopping cart.

  • Sequence products across phases
  • Swap or add items on a set cycle
  • Time refills to real usage, per product

Recover failed payments before they cost you the customer.

A card declines and most tools just cancel the subscription. Gro retries on the schedule that recovers the most, then nudges the customer over email and SMS, so a routine payment blip doesn’t lose you the subscriber.

  • Smart retries Automatic retries timed to when a card is most likely to clear, not a fixed loop that gives up early.
  • Email reminders Branded “update your card” emails go out automatically while it retries.
  • SMS reminders Text nudges for the customers who never open email, so more cards get fixed.

Sell the routine, keep the customer.
