Built to retain, not just raise.

The three things every fundraising team needs to turn one-time donors into long-term, recurring supporters.

See every donor clearly.

Real-time dashboards show which donors are growing, slipping, or ready to upgrade — across every campaign, segment, and giving trend. No more exporting to spreadsheets or waiting for quarterly reports to know where attention matters most.

Reach donors on text.

Native SMS built into the donor workflow — not bolted on. Send personalized texts triggered by donor behavior. Reach donors 1:1 or to entire segments. The channel most fundraising platforms still treat as a third-party add-on.

Build recurring giving.

Access our suite of recurring Giving Programs built to convert one-time donors into monthly supporters. Most platforms let you accept recurring gifts; Harness is built to grow them.

“Harness has let me do more of the fundraising with less team. I've been able to do a similar amount of outreach and data tracking despite missing two full time staff.”
