The dessert is theirs. So is the program.

Rockaberry is a dessert institution in Montréal's Jean-Talon area — a real counter with real staff and a real rush. Perkaria's job there isn't to make the desserts worth coming back for; they already are. Its job is to make sure the person paying for a slice tonight has a reason, and a way, to be back.

The program runs under the Rockaberry name, not ours. The card on a member's phone, the stamps on it and the gift card sold at the counter all carry their brand. Perkaria is the plumbing, not the sign.

A paper punch card builds a habit, but it builds nothing else. It gets lost with the progress on it, it never learns a name, and the shop that stamped it nine times still has no way to reach the person holding it. A counter can serve someone weekly for a year and hold not one piece of information about them.

Joining happens at the counter, person to person. A staff member enrols the customer in a few seconds during the transaction — consent asked out loud, not buried in a form — and a text message with a magic link puts the card on the customer's phone, in the browser it already has. No app to download, no password to invent.

From then on, every visit is the member's QR scanned at the counter. The rest of the Growth feature set runs alongside: gift cards sold at the register, and the review ask after visits that actually happened.

Perkaria never plugs into the register. The counter tablet sits beside the POS, staff sign in with a PIN, and every stamp and redemption lands as pending until the nightly reconciliation checks it against the day's sales export. Nobody at the counter waits on a sync, and a stray tap never quietly becomes a giveaway.
