Ballerine

Ballerine is an open-source compliance and risk management infrastructure platform that automates KYC (Know Your Customer) and KYB (Know Your Business) workflows for fintech companies and financial institutions — providing the orchestration layer that connects identity verification vendors, document processing, business registry lookups, and compliance decision logic into automated onboarding and ongoing monitoring workflows. Founded in 2022 and a Y Combinator S22 graduate, Ballerine raised $5.12 million led by Team8 and has 1,500+ developers on its GitHub with dozens of fintech companies using the platform in production.\n\nBallerine's open-source approach (the core workflow engine and integration framework are open-source) provides a distinct competitive positioning — fintech companies can self-host the compliance infrastructure for full data control, avoiding the data sharing concerns of SaaS-only KYC platforms. The platform orchestrates across multiple verification vendors (Onfido, Jumio, Socure for identity verification; business registry APIs for KYB) through a unified workflow, allowing companies to switch vendors without rebuilding compliance logic. Compliance teams define rules and decision trees, while the platform handles the data gathering, vendor routing, and status tracking.\n\nIn 2025, Ballerine competes in the KYC/AML automation and compliance orchestration market with Alloy (the leading compliance automation platform), Unit21, Seon, and larger risk platforms including Jumio and Acuant for compliance workflow automation. The compliance technology market has grown substantially as financial regulations have intensified and fintech companies need to scale onboarding without proportionally scaling compliance headcount. The open-source model builds developer trust and community-driven contributions while enabling enterprise commercial licensing for support and managed hosting. The 2025 strategy focuses on growing the enterprise commercial customer base, expanding the pre-built workflow templates for common use cases (crypto onboarding, bank account opening, merchant onboarding), and deepening the vendor integration ecosystem.
