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.
Lensmor is a next-generation AI-native Event Intelligence and GTM (Go-To-Market) Signal platform tailored for B2B enterprises. Unlike traditional providers that simply sell static attendee lists, Lensmor solves the critical challenge of converting "Who is there" into "Who is ready to buy." By aggregating data from over 160,000 top global B2B events, Lensmor powers a three-tiered intelligence engine: Event Aggregation, Dynamic Lead Graphs, and Deep Intent Analysis, equipping sales teams with actionable intelligence that goes far beyond static spreadsheets.
StackScan LensmorStackScan's answer
StackScan combines technology stack discovery and keyword-intent research in a single platform, allowing users to find websites not only by the tools they use but also by what they are targeting online. With coverage across 50,000+ technologies and 100M+ domains, it provides scalable, filterable, and export-ready web intelligence.
Lensmor's answer:
Lensmor is the only AI-Agent-native platform in the pre-show exhibitor intelligence space. While competitors like Vendelux sell static attendee databases, Lensmor lets sales reps describe their ICP in plain language and instantly get a qualified prospect list โ enriched with verified contacts and AI-drafted outreach โ weeks before the event. The entire workflow from discovery to first message takes minutes, not days.
StackScan's answer
StackScan focuses on practical usability, broader stack coverage, advanced filtering, and scalable exports without unnecessary complexity. Users can quickly generate highly targeted datasets using filters like country, TLD, industry, and technology combinations, making research and lead generation faster and more precise.
Lensmor's answer:
Vendelux, the category leader, is a traditional database product built around human sales cycles. Lensmor is Agent-first and self-serve: no onboarding calls, no static exports. B2B teams in tech, finance, and consumer industries can run a full pre-show prospecting workflow โ find exhibitors, enrich contacts, draft outreach โ without waiting on a vendor. For teams that want speed over depth of enterprise features, Lensmor wins on time-to-pipeline.
StackScan's answer
StackScan is built for marketers, growth teams, agencies, sales teams, analysts, SaaS companies, and researchers who need structured web intelligence for prospecting, competitor analysis, market research, or technology adoption tracking.
Lensmor's answer:
B2B marketing and sales teams (Manager level and above) at tech, finance, and consumer companies that actively exhibit at trade shows. They spend significant budget on event participation and want to convert that spend into measurable pipeline โ not just badge scans.
StackScan's answer
StackScan was created to simplify the process of finding reliable website and technology data at scale. Existing solutions often felt limited, expensive, or difficult to use for targeted workflows, so StackScan was built as a practical and scalable platform that combines technology detection, keyword discovery, and bulk data access into one system.
Lensmor's answer:
The founding team observed that the pre-show exhibitor intelligence market is massively underpenetrated โ Vendelux is the only real player, and it operates on a traditional data-sales model. With AI Agent technology maturing in 2025, building a self-serve, AI-first version of this workflow became viable for the first time. Lensmor was built to give any B2B team the same pre-show intelligence advantage that was previously only accessible to large enterprise sales orgs.
StackScan's answer
StackScan is built using modern web technologies, large-scale crawling systems, distributed data processing, and technology fingerprinting engines designed to analyze and structure massive amounts of web data efficiently.
Lensmor's answer:
Large language models (Claude by Anthropic) for the AI Agent layer, large-scale web crawling and data aggregation covering 160,000+ global B2B events, contact enrichment APIs, and a REST API backend supporting CRM integrations with HubSpot and Salesforce.
StackScan's answer
StackScan is used by agencies, SaaS businesses, growth teams, researchers, and data-driven organizations for lead generation, market intelligence, and competitive analysis across multiple industries.
While itโs still in early stage, its lifetime deal is really a great value. Must get if youโre into lead generation.
Lensmor looks especially promising for teams working around exhibitions and trade shows. It feels focused, practical,and much more relevant than generic market monitoring tools. I like that it seems built to help users quickly spot useful industry and competitor signals without getting lost in noise.
