On November 14, we completed our acquisition of Stytch, an identity platform for AI agents that’s built for developers. Stytch’s talented team and proven technology will help Twilio augment our roadmap and build an intelligent identity layer that anchors the entire Twilio Platform in support of our vision: a world where every digital interaction is amazing.
Trusted customer communication and engagement have always been at Twilio’s core. As we evolve our platform to encompass a reimagined customer journey – bringing together communications, data, and AI – one truth has become increasingly clear: as customers engage across channels with both humans and AI agents, orchestration, intelligence, and verified identity are essential.
For brands, secure authentication is a critical building block of the customer engagement journey. Twilio has long provided trusted authentication solutions, including products like Verify and Lookup. Our customers have relied on them, and fraud prevention services like Fraud Guard, for years to complete billions of authentications and prevent fraud.
Today, we're witnessing a generational transformation in digital identity. What was once a back-end authentication tool is becoming a core enabler of trust, growth, and intelligent engagement. In the age of AI and agentic systems, identity must evolve beyond static credentials into a dynamic, privacy-preserving framework that verifies trust in real time. This is about more than security, and is foundational to how businesses acquire, engage, and retain customers – connecting authentication, fraud prevention, and personalization into a unified experience.
AI Agent Authentication
AI agents are also redefining digital systems, shifting them from rigid workflows to adaptive, context aware, and autonomous. Businesses building AI agents need four foundational capabilities:
- Communication across multiple channels, including text, voice, email, OTT, and web chat.
- The ability to connect and orchestrate multiple agents.
- Access to customer memory that effectively activates on contextual data.
- A robust AI identity management and fraud prevention solution.
Current authentication solutions like passwords, passkeys, FaceID, 2FA, and static verification have served businesses well and will remain effective within controlled domains, but they are insufficient for managing the complexity of cross-domain, multi-user, and delegated operations that characterize modern agent ecosystems. As protocols such as the Model Context Protocol (MCP) gain adoption, the need for consistent, interoperable identity standards has become clear.
So what’s in store for the future?
Abstracting away complexity for builders with simple, trusted, and smart building blocks has always been at the core of Twilio's product strategy. Stytch's developer-focused team and proven modern authentication technology will augment our Twilio Platform roadmap, and our investment in AI agent authentication and verification will enable secure, personalized, and delegated experiences.
Together with the Stytch team, we will bring to you next generation authentication capabilities built for the era of generative AI. These will include:
- A unified identity across web, mobile, and all customer touchpoints for agents and humans.
- Ability to identify humans, trusted agents, and rogue agents.
- Real-time fraud prevention, powered by contextual data and advanced device intelligence.
This is how we ensure every interaction is amazing – with identity as the foundational layer of the Twilio Platform making it possible.
We’re excited to welcome the Stytch team and start building the future of hybrid identity. Together we look forward to helping businesses build trusted, AI-powered customer experiences that drive growth while protecting what matters most: the relationship between brands and their customers.
