Let agents profile any website's tech stack
QX uses BuiltWith to detect what tools a site runs on, find lookalike accounts, and surface buying signals—so your team chases real opportunities, not dead ends.
Stop manually checking sites, guessing tech stacks, and missing switch signals. Hand it to an agent.
Find accounts that fit your wedge
Pull lists of sites using a specific technology, filter by region, traffic and spend, and drop fresh, qualified accounts straight into your pipeline—no spreadsheets, no scraping.
Every account, fully profiled
Agents look up each domain on demand, attach its full tech stack, financials and history, and keep CRM records current—so reps walk into every call already knowing the buyer.
Catch adoptions and churn early
Watch target domains for new tools added or competitors removed, then alert the right rep with context the moment a switch happens—turning quiet research into timely outreach.
