Find companies using your competitors, and know when their stack changes.
StackProspect monitors the public technology infrastructure of B2B companies and surfaces accounts that match your technical ICP or show meaningful infrastructure changes.
Search by cloud, CDN/WAF, identity, observability, API, DevOps, AI, payments and hundreds of other technologies.
Turn a technical ICP into a company list.
Real searches against the live catalog. Open one to see matching companies and the technologies that qualified them; a free account explores every result.
Static technology lists tell you who fits. StackProspect shows you when something changes.
A removed vendor, a newly adopted platform or a first-observed API technology is a recently observed infrastructure change: an account worth investigating while the change is fresh, and a possible buying signal, not a certainty.
Prioritize accounts while their infrastructure is actively changing.
