Hey Vincenzo F. one approach that’s worked decently for us is using the “BuiltWith” or “Datanyze” enrichments in Clay to get tech stack insights you can also try parsing company websites with the Clay "Extract from Website" step to scan for keywords like “hosted on AWS,” “Google Cloud,” or “Azure” in the footer, legal pages, or job posts not always 100% perfect, but usually gives a strong hint happy to help you set it up if you’d like!
