anVendor is a subscription intelligence platform that identifies companies using specific software vendors and estimates their annual spend. Using live scanning technology, it detects current subscription evidence, unlike tools relying on website code or external models. Users can search SaaS vendors or competitors to find paying companies ranked by estimated spend or perform reverse searches to view a company's full subscription stack. The platform matches seat counts to vendor pricing tiers for conservative spend estimates based on public list prices. Filters by location, industry, and company size refine results. Continuous live scans keep data current, removing undetected services. Vendor pricing is stored with source URLs and verification dates for transparency. It analyzes vendor-side signals, including services behind login walls. Lead searches are unlimited, while live checks and analyses consume credits from tiered plans.
