Overall Satisfaction with Datanyze
We use Datanyze before prospecting or discovery calls to get background on a prospect company's existing tech stack. This facilitates more natural conversations and enables us to demonstrate how we'd plug into their existing environment rather than having to pepper them with 20 questions at the start of each call.
I've used products like Builtwith and Wappalyzer and neither compare to the level and organization of data within Datanyze. It's much more robust and easy to access. However, it isn't perfect and sometimes needs to be updated, or removed and re-installed simply for it to function
