Solaris

Solaris is a Berlin-based fintech infrastructure platform that lets financial institutions and fintechs launch their own digital banking products without building tech from scratch. Rather than wrestling with legacy core banking systems, clients plug into Solaris's cloud-native API layer to issue cards, manage accounts, and process payments at speed.

The company operates in the shadows of most consumer apps—you won't see the Solaris logo in an app store—but its backbone runs through dozens of European fintechs, neobanks, and traditional financial institutions. Think of it as the plumbing that powers other people's banking ambitions.

Solaris dominates a specific niche: the BaaS (Banking-as-a-Service) and embedded finance layer for Europe. While competitors like Thought Machine and Temenos chase enterprise banking overhauls, Solaris stays focused on the modern fintech workflow. Its modular design appeals to companies that need speed and flexibility, not a 10-year implementation project.

In a market crowded with infrastructure plays, Solaris has become essential plumbing for European digital banking. It sits at the intersection of regulatory compliance, technical simplicity, and startup ambition—precisely where the next wave of European fintech is being built.
