Multifactor is redefining zero-trust identity security for the AI era. We build cryptographic infrastructure that lets humans and AI agents securely share access to online accounts without ever exposing credentials. Think of it as turning any online account into a shareable, revocable, cryptographically guaranteed permission link.

• The timing is perfect. AI agents are about to touch every account you own — your bank, your email, your calendar, your company's AWS console. And the entire identity layer of the internet is held together by authentication mechanisms that originated in the 1960s. We're not patching it – we're replacing it.
• The science is real. Our core tech (MFKDF, MFCHF) has been peer-reviewed at USENIX Security, presented at DEF CON, and is built on patents that took a decade of research.
• The structure is intentional. We're a registered public benefit corporation. That's not marketing — it's in our charter. The person who joins us will help build a company that takes the mission as seriously as the math.

We recently raised a $15M seed round led by Nexus Venture Partners, with participation from Y Combinator, Taurus Ventures, Pioneer Fund, and operators from across security, AI, and enterprise software. With your help, our technology can impact millions of users in the near future.
