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