Inkbox now offers cloud-hosted environments where AI agents can maintain persistent working contexts and use dedicated phone numbers and email accounts. To fund the rollout of this infrastructure, the company secured $5.3M in a seed round led by Peak XV. The new service allows agents to save files and installed tools between sessions and automatically enter a sleep state when not in use to lower compute expenses.
The investment round included contributions from Guillermo Rauch, Henri Stern, and Jonathan Frankle. The platform supports agents built on the Codex and Hermes models and utilizes an open A2A protocol to allow autonomous agents to delegate tasks to one another. Since its debut via Y Combinator four months ago, Inkbox has processed millions of messages for its users.
