Dropbox and Box employ a bit of a hybrid model. For SMBs, there's a self service model that's low touch but for enterprises, the sales + customer service is very high touch and requires a lot more customization. BI tools such as Periscope, Looker, Mode, Tableau, etc are also a bit of a hybrid. Usually starts off with an individual playing around or looking for a tool (pretty self service), but a full company deployment is much more hands on and high touch. Following the framework that Patrick provides, odds are that any company that has "sales engineering" or "integration engineering" for a SaaS will likely be high touch (unless they're doing it wrong =D)
