This is the best community tool that's found its way to Appsumo so far. I feel sorry for the people who grabbed the other tools beforehand because Heartbeat trumps them all! It's already polished and feels like a mature platform, and the founders seem passionate and knowledgeable about building a community. You can ultimately create unlimited sub-communities thanks to its privacy settings and the new course feature is awesome as well! I'll be moving over my courses to Heartbeat so that I can have a community + LMS experience in one. The ONLY thing I really wish for is for Heartbeat to allow for sign ups/registrations for my users through the mobile browser WITHOUT forcing them to download the app. That's really the biggest weakness so far since many don't want to download an app to sign up. They want to sign up to look inside before committing to an app. But besides that, 5 tacos from me!
