Boast is super easy to use on both the back end and the client-facing side. I like how easy it is to integrate with your website, and how easy it is for clients to easily submit video either through their webcam or by uploading a pre-recorded video. While it's geared towards people who are gathering client testimonials, I have also used it for collecting video content from conference participants and it works perfectly. I use to chat/conference with customers even. Review collected by and hosted on G2.com.
