At Lerian, we build financial infrastructure that gives institutions control. We combine deep financial expertise with modern, open technology to help organizations operate independently, scale confidently, and adapt without friction. We don’t believe in black boxes. We believe in clarity, ownership, and long-term autonomy.

What we do

We help financial institutions design and operate modern core banking ecosystems using open technologies. Our approach prioritizes:
  • Independence over vendor lock-in
  • Transparency over opacity
  • Architecture over shortcuts
We enable teams to move faster — without compromising control. Learn more about our mission and values →

Our Core Banking Vision

Core banking should not be a rigid service. It should be a programmable platform. Our vision brings together modular architecture, composability, and operational control — so institutions can evolve at their own pace. Built to scale. Designed to adapt. Structured for real-world complexity. Explore our Core Banking architecture →

Open Source Excellence

Open source is not a marketing label for us. It is a foundation. Midaz was designed to be extensible, transparent, and production-ready — giving developers the freedom to build, integrate, and innovate without hidden constraints. You can inspect it. Extend it. Own it. Discover our Open Source approach →
