How do you build a viable subscription business? Well, knowing your customers' needs better than they do themselves is a good start.

In this episode of Retention Masterclass, we chat with former Google product manager Nick Hobbs about retention, acquisition, and product strategy for subscription-based businesses. Hobbs worked on the Google self-driving car team and led Google's iOS app. In our discussion, he chats about what he's doing with Brief, his new subscription-based news services that is hot among millennials and is doubling in customer size every month organically, without paid advertising.

The result: literally startling insights and solid nuggets for anyone growing a subscription-based service or app.
