A few quick ideas:
1. hook your own SaaS app up to Zapier so all of our users (and your customers!) can use it
2. write an integration for a SaaS app you don't own but want to integrate with
3. connect your in-house tools to external SaaS apps through Zapier
I originally had a skype chat with Mike thinking that integrating with them would be a back-and-forth dealing with our APIs. Nope. We had Ronin integrated within 15 minutes via a web UI. All you have to do is drag and drop stuff around and fill out a few forms. I think this is the coolest part of what they've built.
Good luck guys! Good job so far.
Small nitpick: there seem to be some "undefined"'s in the "spinning list" of data-triggers.
We got a lot of feedback about that and reduced the number of emails we send now. Really sorry about that.
