Solaris SE

What Solaris SE does

Solaris SE is a Berlin-headquartered Banking-as-a-Service (BaaS) platform founded in 2015 that holds a full German banking license (Vollbanklizenz), enabling it to operate across the entire European Economic Area. The company provides a cloud-native, API-based technology stack that allows businesses—including SaaS providers, fintechs, mobility platforms, travel companies, and large non-financial corporations—to embed compliant financial services into their own products under a B2B2X (neutral infrastructure) model. Its product surface spans white-label digital banking (accounts with local or virtual IBANs), KYC and KYB identification, branded debit, prepaid, and credit card issuance, SEPA payment sending and acceptance (including SEPA Instant and Batch Payments), and consumer lending including BNPL (Splitpay). The platform is composed of 400+ RESTful API endpoints, a Data Mesh architecture for decision-making and regulatory compliance, and certified security (PCI DSS 4.0, ISO 27001, SWIFT, DORA, EU AI Act, GDPR). Noted enterprise customers include ADAC, Samsung, Bitpanda, Tomorrow (100,000+ end customers), and Boerse Stuttgart Group.

Solaris operates a B2B quote-based revenue model combining subscription fees for platform access with transaction-based fees on payments, card issuance, KYC, and lending services. Distribution is hybrid: direct enterprise sales for large strategic accounts, API self-serve and sandbox onboarding (xs2a-portal.solaris-sandbox.de) for smaller developers, and an embedded/white-label partner model. The company employs 400+ people across 44 locations and more than 60 nationalities, with offices in Berlin, Paris, Milan, and Madrid. Since 2015, Solaris has raised over EUR 530 million from a mix of strategic and financial investors including BBVA, Visa, ABN AMRO, Samsung Catalyst Fund, Lakestar, Yabeo, Global Brain, Holtzbrinck, CNP, Vulcan, Boerse Stuttgart Group, and—most recently in February 2025—SBI Group, which became the majority shareholder via a EUR 140 million Series G round.

Solaris is currently in a strategic transformation phase. In September 2024, it discontinued major parts of its EMI business (formerly Contis, with a EUR 123 million write-down contributing to EUR 178 million in 2023 losses), executed a workforce reduction of approximately 20%, and replaced its CEO and CRO in December 2025 with executives from flatexDEGIRO. In March 2026, the company announced a strategic pivot to become "Europe's first AI-native bank," with AI agents taking over operational processes while maintaining human governance, and a focus on accelerating the path to profitability. AI-driven AML systems have already been deployed to resolve prior BaFin regulatory challenges, and the core payment ledger was migrated to ACI Worldwide's ACI Connetic cloud-native platform in September 2025.
