Subscription fulfillment without the spreadsheets

Subscription boxes aren't picked one-by-one — they're assembled in batches. Curation lists, custom inserts, ship windows, skip/swap requests, churn cohorts — there's a lot of state to track.

We integrate directly with ReCharge, Bold Subscriptions, Shopify Subscriptions, and Stay AI to receive your ship window, batch-assemble boxes for the month's curation, and ship in waves to hit the same delivery date for every subscriber.

Scheduled batches

Monthly, quarterly, or custom shipping cycles.

Custom curation

Different boxes for different cohorts, themes, or tiers.

Skip / swap support

Last-minute curation changes flow into the batch.

Branded unboxing

Custom inserts, tissue, ribbons, and printed cards.
