Legacy core banking is broken. It's a monolithic bottleneck holding back the world's largest financial institutions. We are building the breakout solution: an open, AI-native "Thin Ledger" designed to replace brittle, mainframe-era systems with an elegant, composable, and unbreakable platform. If you are passionate about architecting mission-critical distributed systems and want to define the foundation of an industry-wide shift, join us.
About OpenCoreOS
We are building the operating system for modern finance. Our approach is fundamentally different:
- A "Thin Ledger," not a thick core: We provide a hyper-performant ledger using Go, Kafka, and multi-region distributed databases. This gives banks a simple, powerful, and open foundation to build on, not a monolithic cage
- AI-native by design: AI isn't an add-on; it's woven into our fabric. We use it to power autonomous operations, create agentic development workflows, and build an intelligent, self-healing system
- Unbreakable and open: We engineer for five-nines reliability and bulletproof consistency, targeting the scale of a Tier-1 bank managing hundreds of millions of transactions daily. By building on open technologies and shaping new standards, we ensure our platform provides a foundation for innovation, not another form of lock-in
- Backed by proven industry builders: Our leadership team combines the strategic insight of ex-McKinsey banking, product, and engineering experts with the battle-tested experience of a founder who built and scaled a mission-critical enterprise fintech company serving the world's largest banks. This is paired with the firsthand operational knowledge of former global bank CIOs, giving us an unparalleled understanding of the market we are redefining
