The story

Founded 2003 as German payment processor Heidelpay. Rebranded to Unzer in 2020 to consolidate 13 acquired entities under one brand, evolving from a domestic acquirer into a pan-European PSP with BNPL, POS, and e-commerce coverage. Moved HQ to Berlin in 2022 to underscore the European ambition. Focus is on merchant-facing payments plus a whitelabel BNPL/invoice/installment stack that Unzer underwrites itself.
