Introduction

Detect the complete tech stack behind any company domain. One API call, real-time results.

Pass a domain, get back every tool they use, organised by category.

How it works

We scan multiple public data sources in parallel and cross-reference signals for accuracy. No scraping, no guessing, no manual research. Only verified signals.

Results typically include 25-40 tools for mid-market companies, covering:

• Email & identity — who handles their email, how they authenticate users
• CRM & sales — what CRM they run, marketing automation, sales tools
• Analytics & tracking — web analytics, session replay, advertising pixels
• Cloud & infrastructure — cloud providers, CDN, monitoring, error tracking
• Developer tools — CI/CD, version control, feature flags
• Collaboration — project management, communication, documentation

$
curl https://api.casestudies.dev/v1/enrich/launchdarkly.com \
