Inkbox lands $5.3M seed for AI agents with their own persistent computers
What's the deal? Inkbox has raised a $5.3 million seed round and launched cloud-hosted AI agents that each get their own persistent computer and a set of real communication channels. The San Francisco company, part of Y Combinator's Summer 2026 cohort, announced the funding on November 10, 2026. Peak XV led the round.
What's the endgame? Inkbox's core product is an AI agent that lives on a cloud computer and keeps its files, installed tools, and accumulated context between sessions. The agents wake themselves up when a message or task arrives through a connected channel, run scheduled jobs, and enter a sleep mode when idle to keep costs down.
Why channels matter: Inkbox says its agents integrate with email, iMessage, WhatsApp, and Slack, so an agent can be reached the same way a coworker can. A built-in credential vault lets agents log in to services without passwords stored in plain text, and a provisional workspace process lets them sign themselves up.
The numbers: Inkbox reached $300,000 in annual recurring revenue by September 2026, within four months of its Y Combinator launch. It has reportedly processed millions of messages for agents since launch.
Founded in 2025 by Ray Liao, Alex Wilcox, and Dima Vremenko, Inkbox grew from a three-person team.

The signal: The round arrives amid a sharp investor push into infrastructure that gives AI agents dedicated, persistent computing environments. In October, Daytona raised $60 million at a reported $1 billion valuation for its "Agent Cloud," and rival E2B said in November it had passed $100 million in annualised revenue. Inkbox's integrated bet — compute plus channels and agent identity — is broader but enters a crowded field, so its fate rests on whether customers adopt the full package.
