Deutsches Zentralinstitut für soziale Fragen

What Deutsches Zentralinstitut für soziale Fragen does

DZI is a Berlin-based German foundation (Stiftung bürgerlichen Rechts) founded in 1893 and reorganized under civil law in 1969, operating as an independent evaluator and information hub for the German charitable sector. Its core products are the DZI Spenden-Siegel certification (a donation seal issued to qualifying charitable organizations after assessment of governance, accountability, and fundraising conduct), the SoLit social work literature database, a specialized library on social work, and — until 2022 — the Soziale Arbeit journal, whose publishing was transferred to Nomos Verlag. The institution serves three primary customer groups: charitable organizations seeking certification and credibility with donors, individual and institutional donors seeking verified giving options, and social work researchers and practitioners using its information assets.

Revenue is assembled from four streams: institutional public grants from bodies including LAGESO Berlin, BMFSFJ, and BMZ; Spenden-Siegel certification fees (a EUR 500 base plus up to 0.04% of audited charitable revenues, capped at EUR 15,000 per organization); SoLit database subscriptions; and fees from professional services and publications. With 1–10 employees and a portfolio of major certified organizations spanning humanitarian aid (Welthungerhilfe), food redistribution (Tafel Deutschland), environmental protection (OroVerde, EuroNatur, PRIMAKLIMA), medical aid (INTERPLAST, Gegen NOMA), and family welfare (Heinz Sielmann Stiftung), DZI occupies a niche quasi-regulatory role with no direct domestic equivalent.

Governance is overseen by a board chaired by Cansel Kiziltepe, with Burkhard Wilke as Geschäftsführer (managing director) and additional board members including Christel Neff, Dr. Robin Borrmann, Tim Richter, Gudrun Scheithauer, and Evelin Schneyer. The 2022 transfer of journal publishing to Nomos Verlag signals a deliberate refocusing on certification and information services rather than a publishing business, consistent with a stable, mature institution rather than a growth-oriented one.
