Tokens don't grow on trees. So what are you actually paying for when you pay for AI agents?

In this episode, recorded live in studio, we sit down with Sarah Sachs, Head of AI Engineering at Notion (ex Google, ex Robinhood), to unpack what it means now that Notion is becoming the AI infrastructure real businesses run on. It's a practical conversation for founders, ops leads, chiefs of staff and the accidental systems people who became responsible for how the business actually runs.

What we cover:

The $500 AI bill: when agent cost is broken, and when it's the cheapest hire you'll ever make
Use AI for reasoning, code for plumbing: why Notion Workers exist and when a token is the wrong tool for the job
Permissioned context as the real moat, and Notion as the system of record where humans and agents collaborate
Agent sprawl, vendor lock-in, and staying model optional as the frontier moves
Observe in prod or live in a hallucination: watching what your agents actually do and actually cost

Five takeaways for your business:

Be deliberate about what you hand to AI. Once agents run real workflows, cost stops being abstract.
Reserve AI for judgement and ambiguity.
Redesign workflows around trusted, permissioned context instead of bolting AI onto the mess.
Stay model optional. Keep your context and workflows in a system of record so you can swap models as the frontier moves.
Observe agents in production so you catch hallucinations and runaway spend before they hit your bill.
