did not very well for us. we are a software company selling into healthcare companies and none of our scoring models were good enough.
the problem with infer is that if you are technology company only selling to other software companies the scoring seems to work, otherwise the scope of use cases is limited.
the product integrates well with crm and marketing automation, provides good amount of enrichment for software companies.
the overall product has a very high cost and low return on investment. leads scored higher do not significantly improve revenues and we are not having a problem of volumes (very few businesses do).
It's incredibly ease to use, simple as typing your prospect email and receiving the information you need.
It could be cheaper, the tool is great but could offer a low price tier.
