Payabli builds a developer-focused payments infrastructure for vertical software platforms, combining PayFac-as-a-Service with APIs for pay-in, pay-out, and payment operations. Software companies use it to embed and monetize payments without becoming full payment facilitators, typically via platform and per-transaction fees. Founded in 2020 and headquartered in Miami, it offers PCI DSS 4.0 and SOC 2–compliant tooling, low-code components, and AI-supported operations for onboarding, routing, and reconciliation.
