A procurement manager opens ChatGPT: “SOC 2 compliant tools with Okta SSO, US-only data residency, under $80 per user.” Thirty seconds later she has five vendor names with links. Maybe she clicks one or two. Maybe she just screenshots the list and closes the tab. Three days later she types your brand name directly into Google. By Thursday she's on a demo. You never saw the referral from ChatGPT, but that's where she built her shortlist.
