At 100 users, I'm most concerned with how quickly/easily I can get them on the phone, then how much they talk when they're on the phone.

At that stage, I'm still proving out an idea so having focused users who not only like the app enough to talk to me but who have ideas on how the make the app better is a sign I'm on the right path.

If getting in touch with my first 100 wasn't an option, I'd look for signs they were actively using the app. I would want to find out if the app was indispensable for my users. Sadly, I can't think of a better way to collect that than by picking up the phone.

PS - If you find talking to users tough, reach out and I'd be glad to help you write a script. It sounds phoney, but a good script will help you get through your first three calls. You'll be rolling after that!!
