Short answer: Inkbox is a business AI agent. Gives AI agents their own identity (email, phone, iMessage, WhatsApp, Slack and agent-to-agent messaging) and, since 10 Nov 2026, a hosted cloud computer: the agent wakes when a message arrives, works, and sleeps when idle.

What can Inkbox do?
- Announced a USD 5.3M seed led by Peak XV and launched hosted agents (company blog dated 9 Nov; CEO announcement on X 10 Nov 2026) source
- A hosted agent gets its own cloud computer tied to its Inkbox identity; you pick an agent harness and give it instructions source
- Every email, text, iMessage, WhatsApp or Slack message it is set to handle wakes it up; when idle it sleeps and keeps its files, history and scheduled jobs source
- Runs prompts or scripts once, on an interval or on a cron schedule; has a real terminal and keeps everything on its disk between sessions source
- In chat it asks before using a tool unless you let it go ahead; access is scoped to its own identity and contact rules limit who it talks to source
- Conversations with the same person stay connected across email, texts and calls; agents can also reach each other directly (Agent2Agent) source
- Each identity includes a mailbox, a public URL, an agent-to-agent channel and a credential vault; plugins for Grok Bot, Claude, ChatGPT, Hermes, Claude Code, Codex and OpenCode source
- Identity plans: Free (3 identities), Developer USD 25/month, Startup USD 167/month, Enterprise custom (checked 11 Nov 2026) source
- Went through Y Combinator Summer 2026; launched in July and says it has handled millions of messages for agents; idle time of hosted agents is not charged source
- Sandboxes, so agents you run elsewhere can use an Inkbox cloud computer, are announced as coming soon source
