I built Bloomberry which specializes in just this. You can pass in a company domain and it returns a list of technologies/products we detect that org uses (especially backend/backoffice ones like devops, security, CRMs like Hubspot). I think this fits your use case.

Alternatively, you can pass in a specific technology (ie Github) and we return companies we detected that use it. But this is more for prospecting, not enrichment.

Agreed that Builtwith, in general isnt as good for this. Its more for finding out what technologies a website uses, not what they are using on the backend.

I dont think our API costs an arm/leg, but you should give it a try to see how well it works for your use case.

Just give the page to chatgpt and ask what they use. Give them as much info as you can.
