I'm not a customer, but recently I made a LACRM integration with their new API. All I can say is that their support is really top-notch. They were really helpful and open to feedback. Just by talking with many of them, you can see that the company's culture is great. It is great to talk to people who can actually help you instead of some tier 1 support person.
I've been using Transistor for one month now, and I'm impressed. By far the best podcast hosting out there! Super easy to use and has excellent customer support. It made launching my first podcast a lot easier!
