Problem

Inth addresses the gap between privacy compliance requirements and the software code that actually handles user data. Traditional cookie-consent platforms are often bloated, slow, difficult for developers to customize, and disconnected from regional rules and local-law requirements. That creates both compliance risk—privacy failures can reach production—and a measurable performance cost: Inth cites 89ms of consent-runtime overhead for c15t in comparison with legacy CMPs. The central use case is a fast-moving software team that needs to deploy compliant consent flows across jurisdictions without sacrificing site speed, developer control, or auditability.

The problem is broader than cookie banners. Consent, data-subject requests, vendor oversight, cookie auditing, privacy policies, and terms of service are typically fragmented across legal, marketing, and developer tools, leaving no shared system of record. Inth positions this fragmentation as an operational problem for companies whose privacy obligations are increasingly implemented through code, automated workflows, and AI-assisted changes.

Product / Service

Inth’s product begins with c15t, an open-source, headless, composable consent system that runs inside an application rather than as a black-box tag. Developers can define and ship banners, preference centers, consent categories, regional logic, script loading, and consent records in code, using native SDKs and their own UI components. This makes consent versionable and reviewable alongside the product while preserving localization, customization, and performance.

The commercial model combines the open-source core with hosted or paid compliance infrastructure. Inth offers a free tier and paid Starter and Pro tiers priced at $20 and $50 per month respectively, each with usage fees. The benefit is a consent layer that engineering teams can own and integrate directly, while compliance, security, and customer teams retain records and configuration history that can be verified later.

Market

Inth competes in developer-first consent-management and broader privacy-compliance infrastructure, at the intersection of developer tools, web development, compliance, and trust and safety. Its direct competitive set includes established cookie-consent and CMP vendors such as OneTrust, Cookiebot, and CookieYes, but its differentiation is an open-source, code-native architecture aimed at teams that find conventional CMPs too slow, opaque, or marketing-oriented.

The company is early-stage but has meaningful product adoption signals. YC lists Inth as an active Spring 2026 company founded in 2025 with a three-person team, while its profile says c15t has more than 3 million npm downloads and is used by teams including Zed, Infisical, and Expo; the project also describes use across more than 2,100 sites. Inth’s homepage names additional teams such as Vercel and Unkey. Public pricing is available, but the gathered evidence does not disclose revenue, so traction is best characterized as open-source and customer adoption rather than confirmed revenue scale.
