Full Analysis
Berlin-based Solaris (formerly Solarisbank) was Europe's leading BaaS provider with a German banking license, valued at $1.6B after raising $430M+ from SBI Group, BBVA and Lakestar. From 2022 onwards Solaris faced repeated German regulator (BaFin) restrictions on growth, several rounds of layoffs, the loss of its largest customer ADAC, and a 2024 emergency rescue round led by SBI at a steep down valuation. A defining example of European BaaS failure under tightened regulation.
