Inth

Inth is a San Francisco, Y Combinator-backed company building enterprise privacy governance for teams that ship fast, making consent programmable, observable, and compliant by default. Its foundation is c15t (github.com/c15t), an open-source, developer-first consent management platform with 3M+ npm downloads used by teams like Zed, Expo, Infisical, and Unkey. c15t provides a headless, composable cookie banner, consent manager, and preference center for JavaScript, React, and Next.js, plus a self-hostable consent backend and REST API (@c15t/backend) that also runs as the inth.com managed service. It supports GDPR, CCPA, LGPD, IAB TCF 2.3, Google Consent Mode v2, and Global Privacy Control, with regional policy packs, audit-ready consent records, script and iframe gating, and first-party SDKs and CLI.
