SOLARISBANK AG

Solarisbank AG is a Berlin-based banking-as-a-service provider that launched in 2016 with a full German banking license and later rebranded operationally as “Solaris,” converting its legal form to a European company (SE); it remains supervised by BaFin and the European Central Bank. The company offers API-based modules for accounts with IBANs, SEPA payments, card issuing (primarily Visa programs), compliance and identity services, and selected lending capabilities, enabling fintechs and non-financial brands to embed regulated financial products; through its 2021 acquisition of Contis, it also operates e-money and card programs in the UK under local regulation. Solaris distributes products exclusively via partners rather than direct retail, which concentrates business risk in a relatively small number of program relationships and exposes revenue to partner churn and performance. The firm has been the subject of regulatory findings in recent years relating to risk management and anti-financial-crime controls; BaFin appointed a special representative to monitor remediation and imposed additional capital and governance requirements, prompting management changes and multi-step capital raises to support risk frameworks and planned growth initiatives. The platform’s scale and product set expanded with the Contis integration and large program wins—most visibly a co-branded credit card mandate with ADAC—while other partners have exited or wound down, illustrating volatility inherent in outsourced banking models. Solaris reports continued operating losses typical of BaaS providers building compliance and technology infrastructure ahead of profitability; revenue is predominantly fee- and interchange-based with modest balance-sheet exposure relative to universal banks, and interest income on customer balances can be a tailwind in higher-rate environments but also increases prudential capital demands. Key operational dependencies include card networks, identity vendors, and cloud-based core components, making service quality and incident management material to partner SLAs. The company’s risk profile centers on regulatory remediation, partner concentration, execution of cross-border operations (EU and UK), and integration of acquired platforms, balanced against a capital position supported by external investors and ongoing supervisory oversight.
