xAI's procurement agent found $100K in SaaS waste in a week — the checklist it runs is free though

xAI shipped a Grok Bot marketplace and the template they built for themselves is the interesting one. Haggle Bot connects to Slack and Ramp, finds unused SaaS seats, price-checks recurring purchases, negotiates vendor contracts. Claimed $100k identified in week one.

That number is theirs, about their spend, at their scale — don't anchor on it. But the checks are the same ones that show up in almost every software budget:

1. Seats billed for people not using them. Biggest category almost every time. Pull user list, compare last-login against billing count. Anything untouched 60+ days is where you start.
2. Two teams buying the same capability. Compare categories, not vendor names.
3. Introductory pricing that quietly expired. Year one discounted, year two at list, nobody decided to accept it.
4. Per-seat plans where most seats only read. Downgrade to viewer tier instead of cancelling — easier to get approved, often most of the saving.

The honest argument for the agent isn't intelligence, it's continuity. A manual audit is accurate in January and wrong by April because nothing in it updates. A bot checking weekly catches a departed employee's licence in week two instead of eleven months late.

Two hours of manual work first gives you the baseline to judge whether the bot is worth wiring up. Three or four big annual contracts → calendar reminder beats a bot. Forty subscriptions across distributed teams → the continuity is the point.

Anyone here actually running automated spend checks? Curious whether the savings hold after the first pass or if it's mostly a one-time win.
