My name is Hannes Marais, and I am a founder of a SF Bay Area startup called Oumy. We are looking for beta testers of our visual communication / video messaging service for designers and their clients. The goal is to make it really easy to have technical conversations no matter where you are and what you are designing.
If you are interested in new ways to collaborate on designs, please reach out to me. We are still learning what features are important for Oumy, and so all feedback is very much appreciated. You can learn more about the idea at http://www.oumy.com
