CB Insights Venture Capital Funnel (2023)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.
Key Lessons Learned
1. Regulated fintechs cannot outrun compliance debt
Solaris scaled clients faster than its AML/KYC operations could handle. The €6.5M BaFin fine was less painful than the reputational damage it inflicted on enterprise sales.
2. BaaS margins do not support unicorn valuations
The €1.6B mark assumed BaaS would trade like SaaS. In practice, per-transaction economics and bank-capital requirements cap growth-adjusted multiples far below software peers.
3. Existing investor cramdowns rebase the cap table
SBI going from minority to >70% owner via a €100M cheque means Series A-E shareholders were massively diluted — the classic 'pay-to-play' rescue that erases most upside for prior backers.
