About StackSee
Real-time technology intelligence for sales teams. Know what technologies your prospects use - powered by live scanning, not stale databases.
Our mission
Making technographic data accessible and actionable for sales teams. We believe every sales rep deserves current, accurate data about the technologies their prospects use - not outdated crawl results from months ago.
StackSee was built to replace the guesswork in sales prospecting. Instead of relying on stale databases or manual research, sales teams can instantly enrich their prospect lists with real-time technology intelligence.
What we do
StackSee is a real-time technographic enrichment platform built in the Netherlands. Sales teams input a list of target account domains, and StackSee scans each in real-time to return structured enrichment payloads covering CMS, analytics, payments, marketing automation, chat, CDN, hosting, frameworks, and more.
With detection support for 6,000+ technologies, StackSee enables precise targeting like "these 47 companies use HubSpot Marketing but not HubSpot CRM" - the kind of insight that turns cold outreach into relevant conversations.
Real-time website scanning
Live analysis, not stale crawl data. Every scan reflects the current state of a website.
6,000+ technologies
Comprehensive detection across frameworks, CMS, analytics, payments, and more.
Enrichment API
Integrate technographic data directly into your CRM, outbound tools, and sales workflows.
Bulk enrichment
Upload a list of domains, get back structured tech stack data for every account.
How it works
StackSee uses a multi-layered detection approach that goes far beyond simple HTML scraping. Our analysis engine combines several techniques to achieve the highest accuracy in the industry:
Browser fingerprinting
A headless browser visits each site just like a real user, capturing the full rendered page including dynamically loaded content.
Network analysis
Every network request is intercepted and analyzed - script sources, API calls, CDN patterns, and third-party service connections.
DOM inspection
The page structure, meta tags, inline scripts, and CSS are analyzed against thousands of technology-specific patterns.
AI enrichment
Machine learning models supplement pattern matching to identify technologies that resist conventional fingerprinting.
The team
Built by engineers who believe sales teams deserve better data than stale crawl databases. We come from backgrounds in web infrastructure, browser automation, and data engineering - and we are focused on one thing: making technographic enrichment as accurate and fresh as possible.
StackSee is built and operated from the Netherlands. We are an independent, product-led company - not buried inside a larger platform, not dependent on historical crawl data from years ago.
Why StackSee
vs. BuiltWith / Wappalyzer
Not a lookup tool - real enrichment that integrates into CRMs and outbound workflows.
vs. Clearbit
Independent product with deeper technographics. Clearbit is buried inside HubSpot - we stand alone.
vs. ZoomInfo / Apollo
Deeper, more accurate technographics specifically - complementary, not competitive.
