Small change
Big difference

Money has changed. Round-Ups round-up every purchase your donor makes to the nearest dollar, donating the spare change directly to your organization, completely tax free. It’s seamless. It’s easy. And it means no more awkward cold calls or expensive direct mail. The average American gives $420 dollars this way, just by going about their daily life.

Case Study

From random to regular donations

Back in 2015, The Ronald McDonald House in Tampa signed up to Harness and trialed our Round-Ups technology. Straight away they could see the big change the little change was making. They went from 3-5 Annual Events a year and a bunch of unpredictable, random gifts, to receiving a steady $35 dollars* a month from each donor.

They told all the other local houses about us. And now Round-Ups has been rolled out across all the Ronald McDonald Houses in Florida. Which means more children than ever are getting the help and care they need.

*This is the average monthly amount a donor gives with Round-Ups.
