TL;DR

The organization uploaded 5,007 contacts into a shared Potential Donors List on FundGen. For most of the campaign, ambassadors coordinated the way everyone does — WhatsApp groups, spreadsheets, manual back-and-forth. In the final five hours, 76 ambassadors switched to the app, claimed their contacts in real time, and pushed together — every contact assigned to exactly one person, zero duplicates. The campaign closed at ₪1,082,809 raised. Of that, ₪181,903 came directly from the list.

The Setup: Real-Time Coordination at the Finish Line

The campaign ran with 220 ambassadors. For most of it, coordination happened the way it always does — WhatsApp groups, spreadsheets, manual back-and-forth. They had a large pool of potential donors: alumni, parents, supporters. The risk was obvious: with that many ambassadors and thousands of contacts, someone was going to reach the same person three times while someone else wasn't reached at all.

They uploaded 5,007 contacts into FundGen's Potential Donors List. In the final five hours, 76 of those ambassadors switched to the app and claimed contacts in real time — each one pulling names directly from the list as the sprint unfolded. Once a contact is claimed, it's locked to that ambassador and hidden from everyone else. By the end, 2,435 of those 5,007 contacts (49%) had been distributed across 76 ambassadors with zero overlap.

Campaign Day: One Shot at the Sprint

This campaign had the classic Charidy shape: a warm-up of a few days, then a single explosive sprint day where the real action happens — matching funds, peak social momentum, every ambassador pushing at once. Of the 1,492 total donations recorded, 1,137 (76%) arrived on the sprint day alone, bringing in ₪894,324 — 83% of everything raised.

The Final Five Hours

The table below compares the morning of the sprint day — before the coordinated push — to the final five hours of the evening, when ambassadors were working their assigned contacts in parallel.

PeriodDurationDonationsAmount RaisedFrom Potential Donors ListRate
Morning8 hours145₪54,55113%~18 donations/hr · ~₪6,800/hr
Final Push (evening)5 hours375₪550,43944%~75 donations/hr · ~₪110,000/hr

The 13% in the morning reflects donors who happened to be on the list and gave organically — not through direct ambassador outreach via the app.

The surge at the end — 4.2× more donations per hour, 16× more revenue per hour — is the sprint in action. End-of-campaign energy is expected on Charidy. What is notable is who was driving it.

44% of the revenue raised in those five hours came from the Potential Donors List — contacts that each ambassador claimed in real time from the app, and personally reached out to on the day that mattered most. At peak, during a single 60-minute window, ₪253,000 was raised in one hour, with more than half of those donations coming from the Potential Donors List.

duplicate assignments across 76 ambassadors

The average donation from an assigned contact (₪484) was smaller than organic donations (₪739) — but they came in volume. Most of these donors likely wouldn't have given at all without a direct, personal ask from the ambassador who had their name.

Why Collision-Free Assignment Changes Everything

When everyone is pushing at once, coordination breaks down fast. In campaigns that didn't use this feature, we've seen it firsthand — the same donor reached three, four, sometimes more times by different ambassadors. Some donors never get contacted at all. The Potential Donors List solves this at the system level: each contact is claimed by one ambassador, invisible to everyone else. 76 people, each with their own set of names, working in parallel with no overlap.

Here, only 76 of 220 ambassadors joined the sprint through the app — a third of the team. Yet they generated 23% of all campaign donations. More time to activate more ambassadors would only multiply that.

Key Rules This Campaign Proved

1 donor per minute

76 ambassadors · 5 hours · 348 donations. When coordination works, pace becomes predictable.

Reach 41% of your list → expect ~17% to donate

Real-world funnel: 5,007 leads → 2,071 contacted → 348 donated. Not everyone answers, but the ones who do convert.

76 ambassadors = 23% of all donations

A minority of organized ambassadors outperformed the rest of the campaign combined. The bottleneck isn't effort — it's coordination.

Late activation still works

These ambassadors joined in the final sprint only. With earlier activation and more ambassadors, the multiplier gets larger.

The Takeaway

The headline (23% of all donations came from people on the list) actually undersells the story. In the 5-hour sprint, it was closer to half the revenue.

That's not a tool. That's a strategy.
