[ 02 · in their words ]

The expiry warning changed everything. People renew when you ask them a week early, not after their budget breaks.

Priya Natarajan

Engineering Lead, Tallow

Tallow is a budgeting app for couples. Most of its users link three or more accounts, and every one of them has a consent that runs out.

Before Sluice, Tallow found out about expired consent when a sync failed. They now listen for connection.expiring and send an in-app nudge with a one-tap renewal link seven days ahead.

The share of connections lost at renewal fell from 9.2% to 2.1% per quarter. Because renewed connections keep their id, Tallow’s budget history stays whole.
