We know your next donors – do you?
Fundraising Day Berlin-Brandenburg | September 23, 2025
On September 23, the fundraising scene meets in Berlin, and we will be there! At the Fundraising Day Berlin-Brandenburg 2025, everything revolves around effective fundraising, innovative strategies, and a solid data foundation. As an experienced dialogue marketing agency, we will show you on site how to achieve more donors, higher response rates, and sustainable engagement with high-quality addresses and cross-channel communication.
The secret ingredient: Our precise donor lists!
Donors don’t just fall from the sky – but we know where to find them. With our validated, GDPR-compliant addresses, you reach exactly the people who really care about your cause. Whether by mail, digitally, or cross-media: your message lands where it is read and understood.
🟠 Donor data with deep profiling
🟠 Regional and topic-specific target groups
Our dialogue marketing specialists Britta Bosma (britta.bosma@trebbau.com) and Petra Henneberg (petra.henneberg@trebbau.com) are looking forward to personal conversations with you at our booth on site. Feel free to arrange an appointment in advance or just drop by – we look forward to inspiring talks with you!
