Website technology stack detector for 1,700+ technologies.

vs others: More convenient than chaining separate technology detection and B2B data APIs because results are unified in a single response, but less transparent than dedicated B2B data providers regarding data source quality and freshness.

** - Access comprehensive B2B data on companies, employees, and job postings for your LLMs and AI workflows.

via “b2b contact database search with multi-dimensional filtering”

Unique: Combines 40+ data providers via waterfall enrichment into a single queryable 450M contact index with multi-dimensional filtering (job changes, VC funding, revenue, recruiting status) rather than simple keyword search like LinkedIn Sales Navigator. Enforces tier-based export limits (100 vs unlimited) to drive monetization.

vs others: Cheaper than LinkedIn Sales Navigator ($59/month vs $99/month) with more structured company data (revenue, VC funding, founding year) but smaller user base means fewer integrations and less market validation than Apollo or ZoomInfo.
