Hey Melissa! Totally worth giving BuiltWith a try β¬οΈ (good call, Willy). In my experience, it's been limited at times to tools that only show up in a Website's HTML/JS, though.
Claygent (specifically the Navigator model) does a really good job of looking for and scraping logos, case studies, news, and other publicly available info to find the tools that don't show up in HTML/JS. Would recommend plugging in the goal and where you think it should look into ChatGPT, have it craft a prompt for you for Claygent, then running that enrichment on 10 rows to see if it's returning what you're looking for.
