TechLeads scans public websites and detects Segment from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is Segment's website count divided by the website counts of all Customer data platform technologies we track; a site using two Customer data platform tools counts for both. Counts were last refreshed on October 9, 2026 and update daily.
