Your AI Agent Now Has a Phone Number, Email, and iMessage

Your AI Agent Now Has a Phone Number, Email, and iMessage

Three founders. MIT, Harvard Med, Northeastern. Summer 2026 YC batch.

They are building the identity layer for AI agents: email, phone, iMessage, and an internet address — for software that doesn't have a body.

Meet Inkbox.

Ray Liao has a PhD in Computer Science from MIT. Dima Vremenko built ML pipelines at Harvard Medical School. Alex Wilcox did ML engineering and computer networking research. They are three people. Their product gives agents a way to exist in communication channels the way humans do.

The problem is obvious once you see it: agents can do incredible things, but they have no inbox. No phone number. No way to receive a text message or take a call. Every interaction requires a human to bridge the gap.

Inkbox solves that. An agent gets its own email address. Its own phone number. Its own iMessage contact. Every interaction flows through Inkbox, so agents are enhanced with multi-channel context — the same email thread across a week, the SMS conversation, the iMessage thread.

Tyler Bosmeny is their YC partner.

The company was founded in 2025, three people in San Francisco. They are live. Agents are already using Inkbox to send and receive messages as if they were people.

The takeaway: we are past the era where agents only exist in a terminal window. The next generation has phone numbers. They have inboxes. They live in your contacts list. And three people from Northeastern and MIT just built the infrastructure for it.
