What the platform includes
Deployment flexibility
You choose how to run the platform:
- Fully managed (SaaS): Lerian handles everything. Your team focuses on configuration and business logic. Fastest path to production.
- Your infrastructure (BYOC): Deploy in your own cloud or on-premises. Full control over data residency, security, and compliance boundaries.
Built for trust and independence
- Source-available core: Midaz, our ledger, is source-available — inspect, audit, and extend the core that holds your money. No black boxes at the foundation
- No vendor lock-in: Standard interfaces and open formats across the platform. You can always move
- Compliance-ready: Immutable audit trails, double-entry enforcement, and regulatory reporting ship built in — not bolted on
- Incremental adoption: Start with one product and expand as needed. No big-bang migration required
