I work at Periscope Data - we do our own lead scoring using home-baked ML through SciPy. It was interesting to see it play out in the real-world - interpretation of features/parameters was definitely important to the people driving the marketing/sales orgs.

We also support linear regression in the product itself - it was actually an on-boarding project for one of the engineers who joined this year, and he wrote a blog post to show them off: https://www.periscopedata.com/blog/movie-trendlines.html About 1/3rd of our customers are using trendlines, which is pretty good, but we haven't gotten enough requests for more complex ML algorithms to warrant focusing feature development there yet.
