2025: Data Sciences’ Strongest End-of-Year Fundraising Performance
January 23, 2026
End-of-year 2025 was the strongest fundraising period we’ve ever delivered at Data Sciences.
Across our non-profit partners, fundraising revenue increased by 57% year over year, driven by more than 15,000 individual gifts across all campaigns. Giving Tuesday alone delivered a record-setting fundraising day, setting the pace for December and beyond.
These results matter not just because they’re strong, but because they came in an increasingly difficult fundraising environment.
Competition was higher than ever. Donor attention was fragmented. Cost-of-living pressures continued. But, regardless, our partners saw some of their strongest fundraising performances to date.
What made this year different
The common thread across our highest-performing campaigns wasn’t timing or tactics. It was a well-planned audience strategy, creative strategy, and scale.
By the time end-of-year arrived, DS campaigns were activating:
- Large, warm digital audiences built throughout the year;
- Email and remarketing lists already primed to convert;
- Creative and messaging informed by months of testing;
- Digital infrastructure ready to scale instantly.
The only thing left to do was execution.
And the payoff was clear: strong peak days, sustained performance across the full end-of-year window, and donation values that held firm even as the market tightened.
Why this matters for fundraising leaders
End-of-year results are often treated as a December problem. Our 2025 performance reinforces a different reality: the outcomes show up at the end, but the advantage is built much earlier.
That’s the model behind Data Sciences’ strongest end-of-year to date.
If you’re thinking about how to enter the next end-of-year period with momentum already in place, we’d be happy to compare notes.
