xAI runs Grok Bot on its own procurement: 'Haggle Bot' finds over $100K in savings

xAI's first-party case study gives a procurement agent access to Slack, Notion, Drive, Gmail, Hex and Ramp: it mapped ~125 vendors, flagged 43 idle SaaS seats worth $14,220, found $85,662/year in unused SKUs, negotiated a SaaS renewal and cut one office-supply order 58% (from $14,629 to $6,143), identifying over $100,000 in direct savings with humans keeping approval over vendor-facing messages and spending.
