Nango is an open-source platform providing integration infrastructure - OAuth, token refresh, webhooks, rate limits and credential storage - so developers and AI agents can connect products via APIs quickly.
Nango builds open-source infrastructure for product integrations. Founded in 2022 and backed by Y Combinator (W23), the company provides the plumbing behind API connections - OAuth flows, token refresh, rate-limit handling, pagination, webhooks and credential storage - so that developers and AI agents can connect products via APIs in hours rather than weeks. Its platform supports more than 800 APIs across any backend language, AI coding tool and agent SDK.
Integration logic is written as TypeScript functions, giving teams direct control over behaviour through a code-first approach. Beyond the open-source core, Nango offers enterprise capabilities including RBAC, tenant isolation, SOC2 certification and a 99.9% uptime commitment. The company reports more than 1m integrations running in production, over 150m customer code executions a month and 400-plus paying customers, with users spanning fintech and AI coding assistants.
The team is fully remote and draws on experience from developer-infrastructure companies including AWS, GitHub, Okta, Snyk and Netlify. Technical work centres on API integrations, authentication and token management, webhooks, AI agents and agent SDKs, and developer infrastructure built largely in TypeScript.
