Lerian
Open-Source Core Banking
Last verified August 17, 2026 · Updated daily
What Lerian is building
Lerian builds Midaz - an open-source, API-first, cloud-native core banking ledger. Think of it as the Linux of core banking: any fintech or financial institution can plug it in, customise it, and own their infrastructure without being locked into legacy vendors like Temenos or Mambu. Key modules include double-entry accounting, reconciliation, orchestration, onboarding, and reporting. It's developer-first and goes to market via open-source community adoption as much as direct enterprise sales.
Why this matters
Every fintech in Brazil eventually gets trapped by legacy core banking vendors. Lerian is building the escape hatch. The founder built Dock, LatAm's first Banking-as-a-Service unicorn at a $1.5B valuation, so he has the Rolodex, the credibility, and the insight to pull this off. Kevin Efrusy, the Accel partner on the cap table, is the same investor who backed Facebook at Series A. This isn't a hobby project. And the company explicitly stated that this seed will fund commercial and customer success team buildout, which is your signal. The press release was explicit: 'The new capital will be directed primarily towards technology investment, with a particular focus on applying artificial intelligence to the platform. Lerian also plans to build out sales and customer success capabilities and step up marketing as it seeks to consolidate its footprint in Brazil while improving international positioning.'
