See your competitor's customers. And what they pay. Live scans find them. Vendor plans estimate their spend. See your competitor's customers or try one of featured services below: How it works Any vendor → customers Enter a competitor or SaaS vendor. See the companies paying for it, ranked by estimated annual spend. Every customer → spend Open any company to see its subscriptions and the estimated annual spend behind each one. Live scans, not guesses We look for current subscription evidence. If a service disappears on a new scan, it drops from the results. See who pays each vendor Choose a service to see its current customers, estimated annual spend, published plans, and the date its pricing was checked. atlassian.comdropbox.comasana.comcalendly.comopenai.comzoom.usfigma.commonday.comgithub.comgrammarly.comdocusign.comreplit.compagerduty.comknowbe4.comAll services → See why anVendor finds leads others miss. anVendor vs BuiltWithanVendor vs WappalyzeranVendor vs TheirStackanVendor vs HG Insights Frequently asked What does anVendor do?+ Enter a competitor or any SaaS vendor. anVendor shows the companies paying for it and estimates each customer's annual spend. You can also reverse the search: enter a company to see its subscriptions. How do I find the companies using my competitor?+ Search leads is the first tab. Enter your competitor's name or domain to see the companies paying for it, each with estimated annual spend. Searching is free. Add location, industry or size filters to discover more matching companies. How do you know what a company pays?+ We price each result against the vendor's own published plan ladder — the tiers on their public pricing page, each stored with the source URL and the date we checked it. The seats we find are matched to the tier that fits, and the result is shown as a floor: "$48k+ / yr". It is an estimate from public list prices, never an invoice or a negotiated rate. How is anVendor different from BuiltWith, Wappalyzer, TheirStack or HG Insights?+ BuiltWith and Wappalyzer inspect website code. TheirStack reads job ads. HG Insights models likely spend from outside signals. anVendor finds current subscription evidence on the vendor side, including for services used behind a login, then estimates what each customer spends from that vendor's published plans. anVendor vs BuiltWith anVendor vs Wappalyzer anVendor vs TheirStack anVendor vs HG Insights Where does the data come from?+ We analyze vendor services alongside publicly available information and look for the signs that a company holds an account with a given service. The method is proprietary and we don't describe it. It never reaches into private, password-protected or access-restricted systems, and uses no browser extension, SDK or tracking script. What does it cost?+ Lead discovery is unlimited. Live checks cost 0.25 credit per lead or 1 credit for a full company analysis. Free includes 3 credits per 30 days; Starter includes 30 for $99/month, Growth 100 for $299/month, and Scale 400 for $999/month. Matching one-time packs never expire. Empty or failed checks are refunded. How accurate is it, and how current?+ A result is current subscription evidence, not an invoice or a guarantee. Where a vendor offers no public signal, we report nothing rather than guess. A new live scan refreshes the evidence, and a service we stop finding drops out of that company's results.
