Only around 2% of website visitors leave their contact details
Sales and marketing teams still operate in their own silos instead of being aligned. Digital marketers drive people to their website and try to get them convert into contacts. Meanwhile, sales teams are cold-contacting people who've never heard of them. This is costing companies billions. By handing marketing insights to salespeople our customers are spending less time cold calling and more time making profit on leads right under their noses.
Leadfeeder shows you the companies visiting your website, how they found you and what they`re interested in.
StackScan helps businesses find and analyze websites based on the technologies they use or the keywords they target. Instead of manually researching websites one by one, users can instantly search across 100M+ domains and identify sites using platforms like Shopify, WordPress, WooCommerce, Webflow, and thousands of other technologies.
The platform provides practical filtering tools that allow users to narrow results by country, TLD, industry, or specific technology combinations. This makes it useful for building targeted lead lists, researching competitors, discovering niche markets, or identifying companies using certain software stacks for outreach and partnerships.
StackScan also supports bulk data downloads, keyword-based website discovery, and structured reporting to simplify large-scale research workflows. With continuously refreshed datasets and scalable search capabilities, it enables marketers, agencies, analysts, and growth teams to access actionable web intelligence quickly and efficiently.
Leadfeeder StackScanLeadfeeder is recommended for B2B businesses, sales teams, and marketers who want to gain deeper insights into their website traffic, identify potential leads, and improve their overall sales and marketing strategies. It is particularly beneficial for companies that rely heavily on digital marketing and have a strong web presence.
