Zaro, a startup developing a shared context layer for AI agents, has raised $5.1 million in a pre-seed round led by Cherry.

Other investors in the round include Convergence founders Marvin Purtorab and Andy Toulis, as well as the co-founder of Hugging Face and the former CEO of GitHub.

The company is building a platform that allows AI agents to read from and write to a shared company knowledge layer spanning emails, call recordings, Slack threads, and documents. The aim is to give agents persistent organizational context while keeping that intelligence inside the company rather than with outside software vendors.

The funding comes as businesses increasingly experiment with AI agents in enterprise workflows, making infrastructure for memory, context, and interoperability a growing area of interest.
