Stytch

We provide authentication infrastructure with APIs and SDKs for developers. You can use our tools to integrate identity, authorization, and security into your web and mobile applications. Our platform includes fraud and risk prevention, and it scales for all customer sizes, from early-stage startups to large enterprises. We support both human users and AI agents.

We offer pre-built frontend components, headless SDKs, and backend APIs, giving developers control over their login experience. Our platform has multi-tenant and user-focused data models, plus granular API access to authentication features. We support enterprise authentication features like Multi-factor authentication (MFA), Just-in-Time (JIT) provisioning, Role-Based Access Control (RBAC), System for Cross-domain Identity Management (SCIM), and Single Sign-On (SSO) for SAML and OIDC protocols. An embeddable admin portal lets customers manage authentication settings, SSO, and SCIM directly from their own dashboards.

For AI agent identity and security, we offer a platform for authentication, authorization, and consent management, including MCP authentication and authorization tools. We can detect and stop malicious or misbehaving AI agents. Our platform also includes real-time fraud and abuse protection, with bot detection, enforcement tools like security verdicts and invisible CAPTCHA, and intelligent rate limiting (including device-level traffic shaping).

We recently joined Twilio. This allows us to combine our identity stack with Twilio’s communication infrastructure and data, strengthening the foundation for AI-powered applications. We continue to develop and support the platform, with a growing focus on building for an agent-centric future.

Our mission is to eliminate friction on the internet. We help developers build identity experiences for both human users and AI agents. We value empathy and ambition.

Our team focuses on improving the developer experience, removing friction, and delivering products quickly to meet customer needs. We’re also committed to the future of user authentication.

We are a fast-growing team of 51-200 employees. We encourage everyone to build strong relationships with customers, collaborate across teams, and constantly learn about our products and challenges. Our work environment values shaping processes and contributing to product feedback, which helps us influence the product roadmap based on customer input. We aim to be credible to a range of audiences, from software engineers to CTOs. Some roles offer a hybrid work model, requiring in-person collaboration in the SF Bay Area a few days a week. Our developer success team provides dedicated support.

We offer employees equity, health care insurance, time off, and paid parental leave.
