A donor links the card already in their wallet. Every eligible purchase rounds up in real time. Then, instead of nickel-and-diming that card every day, Smart Sweep moves the pooled change once a week in one clean line item.
The average card on file generates about $30 a month in round-ups alone, based on monthly transactions. That number includes zero sponsor giving and zero employer matching. The trifecta stacks on top of it.
Day one: sign up, give $10, feel it instantly. The kickstart gift makes donors part of something special from the first minute. Never a $25 month-end batch. Never a subscription in disguise.
The donor stays in control the whole way. Caps, cadence, and pause are donor-set from day one. That control is why they stay.
