Austin Tedesco, Every's head of growth, now spends about 80 percent of his working time inside the Codex desktop app, doing everything from drafting go-to-market plans from a stack of meeting transcripts to rebuilding the company's KPI dashboard.On this episode of AI & I, Dan sat down with Austin to discuss why the agent management interface—a desktop app built on top of a coding agent—is becoming the new operating system for knowledge work, and why Codex has become his daily driver.If you found this episode interesting, please like, subscribe, comment, and share!To hear more from Dan Shipper:Subscribe to Every: every.to/subscribeFollow him on X: twitter.com/danshipperJoin the membership for Where You Live at joinbilt.com/danTimestamps for YouTube:00:00:00 Introduction00:00:57 How Codex went from a tool for senior engineers to a daily driver for knowledge work00:02:42 How Claude Code proved that a great coding agent works for any knowledge work00:07:24 Austin's switch to Codex00:13:48 How Austin set up Codex with folders, keys, and reviewer agents00:18:24 Using Codex to brainstorm automations across Gmail, Slack, and Notion00:22:42 How Austin manages the human review step when Codex is drafting communications00:28:54 Using Codex to build specialized agents inspired by product executive Claire Vo00:31:09 Synthesizing meeting transcripts and Slack threads into a go-to-market plan00:40:15 Building a live KPI tracker in Notion that agents can read00:44:54 Using Codex for recruitingLinks to resources mentioned in the episode:Austin on X: @tedescauDan's January essay on OpenAI's catch-up problem: every.to/chain-of-thought/openai-has-some-catching-up-to-doEvery's vibe check on GPT-5.5: every.to/vibe-check/gpt-5-5
