I've been a closed alpha tester for a few weeks :) I'm a PM at a startup and we have been using roadmap to plan our closed and open alpha launches! We're a distributed team, and we rely heavily on tools to communicate and sync. Smart team, great product.
We just launched Wizeline Roadmap, the fastest way for anyone to create eye-catching visual roadmaps that everyone can understand. Sign up for a free trial at https://www.wizelineroadmap.com/ -- a single-license version of the app is available for free. Let us know what you think!
