Why not just ask ChatGPT?
AI chatbots confidently guess. We verify.
Hallucination-free
Ask an AI what tools a mid-tier AI startup uses and it'll fabricate answers. Our data is sourced from real signals — not generated.
Cross-referencing at scale
ChatGPT knows OpenAI uses Stripe. It doesn't know which 158 other AI companies do too. We map all 8,000+ relationships.
Timestamped and current
Our data has a specific date (April 2026). AI training data is months or years stale — and the model can't tell you when its info is from.
How we collect this data
Multiple verified sources, not AI-generated.
- ●Infrastructure and platform customer lists (public announcements, case studies)
- ●Job postings mentioning specific tools and vendors
- ●Public dependency files, package manifests, and open-source footprints
- ●Curated research and manual verification
FAQ
What data is included?
Full tech stack data for 930+ AI companies, showing which vendors and tools they use internally — cloud providers, databases, AI models, observability tools, auth, payments, and more. This is verified internal stack data, not just public-facing frontend tech.
How often is the data updated?
Data is current as of April 2026. We update regularly and you'll always have access to the latest data.
How is TechStackMap different from BuiltWith?
BuiltWith scans public-facing websites for frontend technologies and charges $295–$995/month. TechStackMap provides verified internal tech stack data specifically for AI companies — including cloud infrastructure, databases, and AI models that aren't visible on the frontend — for a one-time payment of $49.
Who is TechStackMap for?
TechStackMap is built for sales and business development teams at developer tools and infrastructure companies who need to prospect AI companies by their tech stack. It's also used by investors, analysts, and BD teams mapping the AI ecosystem.
Can I search by vendor to find companies?
Yes. You can look up any vendor (like Snowflake, Pinecone, or Datadog) and instantly see every AI company in our database that uses it. This reverse-lookup is one of the most popular features for SDR teams building prospecting lists.
Why is it so much cheaper than alternatives?
Most technographic data providers like BuiltWith ($295–$995/month), Wappalyzer ($250/month), and HG Insights ($25,000+/year) charge enterprise subscription prices. TechStackMap offers a focused dataset — AI companies specifically — at a one-time price of $49 because we believe sales teams shouldn't need to spend thousands per year on prospecting data.
