With YC's help, we’re building the identity security layer the agentic web is missing today.

Multifactor is doing for AI security what
Cloudflare did for web security, Okta did for identity security, and Wiz did for cloud security: defining the category.

So, we're building a secure, user-friendly platform to address this exact problem.

Our product makes sharing account access with anyone, human or AI agent, as simple and secure as sharing a Google Doc.

No passwords exchanged. Just revocable, one-click access.

The core flaw? We’re letting AI agents run our businesses and personal lives by sharing accounts and data insecurely.

For example, a recent attack on Google’s Gemini used a simple calendar invite to control IoT devices, download malware, delete emails, and exfiltrate data.

The agentic era is here, but its foundation is dangerously insecure. The pace of change is incredible, but the risks are growing even faster.

We joined YC because this problem can't wait. We need to move at the speed of the AI revolution, and YC is the ultimate accelerator.
