A recent episode of "Startups for the Rest of Us" mentioned BuiltWith and its new competitor DataNyze:
Rob [11:30]: There are two services I know that actually crawl websites and they can actually figure out what stuff is Built With. The first one is called builtwith.com and these are both SAS subscriptions and they’re not cheap but builtwith.com is the service that I know that several of the kind of outbound legion guys use and they’ll say, “Well, my competitor is X, Y, and Z and it’ll give you a list.” Now, Built With crawls certain amount of websites every so often. The second competitor is more expensive but they crawl daily. So they cannot only tell you who’s using what, they can tell you someone started a trial of this yesterday, like they just installed the code. So it’s much more powerful but they are more expensive. That service is called Data Nyze, it’s data, N-Y-Z-E.com, both of those if you’re willing to put down the money are going to be good services to find out who’s using your competitors and for full disclosure, I am a small angel investor in Data Nyze but I have seen and used the interfaces for both of those tools. So thanks for the question Ryan. - See more at: http://www.startupsfortherestofus.com/episodes/episode-249-f...
