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. Discovering companies is free. Add location, industry or size filters to discover more matching companies. Reveal the rows you tick, or take every company the search can reach with Reveal all.
How do you know what a company pays?+
We match each result to the plans that fit, using published prices and clearly labeled estimates where a public rate is unavailable. Pricing carries a source URL and check date. The result is shown as a floor: "$48k+ / yr". Actual invoices and negotiated rates can differ.
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 uses live scans to find which companies use a service, including software used behind a login, then estimates each customer's spend from sourced plan pricing, with estimated rates clearly labeled.
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. Failed checks and checks that find no subscriptions are refunded. A Reveal all job holds the list price or your whole balance, whichever is smaller, so a short balance shortens the run rather than blocking it; a company checked with no detection pays for the next one, and whatever the job never reaches is released.
How long does an answer take?+
Fresh results can open immediately once you have access. A new live scan for a lead usually takes minutes; a full company scan can take an hour or more for a large company. Scans run in the background and results appear in your account history when ready. A Reveal all request continues after you close the tab.
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.
