Recommendations for Tech Stack Intelligence Tools in E-Signature

Hello,I work as a GTM Engineer for one of the largest scaleups in Europe in the e-signature space, and we’re currently evaluating the best tools for monitoring and identifying the technology stacks used by the companies we’re qualifying. We’ve already tested solutions like BuiltWith and the options available through Clay, but they tend to focus primarily on web-related technologies. What we specifically need is a tech-stack intelligence tool capable of detecting which e-signature solutions a company is using. Ideally, this should integrate with AI so we can use technology-usage signals to track changes within specific account lists or identify when a company adopts or switches to a particular tool inside Clay. If you’ve used any tech stack intelligence tool that worked well for this type of use case, I’d really appreciate your recommendations. Additionally, if anyone has experience with TheirStack, I’d love to hear your feedback. Thank you!
