Kylon launches a company harness linking team members and AI agents in shared chat
Overview
Kylon, a startup led by Quinn Leng, has launched a "company harness" that puts humans and AI agents such as Codex and Claude into shared team rooms, according to Kylon's launch post.
Team members can link an agent running on their own computer and @ mention it in a thread to write code or sort files. Agents can hand off next steps to a coworker, build apps in the conversation, keep their own memory, and access only the accounts the team allows. Kylon's Apps feature runs the databases behind agent-built apps on Databricks Neon, and the product connects agents to Gmail, Slack, and Notion context.
François Chollet argues that isolated agent chats are suboptimal for teams because agents lack what the team has already discussed and decided. He says Kylon runs Claude Code and Codex in a shared environment so agents see team consensus in real time, but he does not measure results. Santiago says he has used Kylon for several days and runs it locally with Codex, and that Kylon can also connect to Claude Code, Devin, or a Kylon Cloud account. Reports do not give pricing or general availability.
