I sat down with co-founders David Gottesman and Chris Amen the other day for a sneak peak. David is a serial entrepreneur who was formerly at Loudcloud, a Marc Andreessen company. In his previous life Chris helped develop streaming media technology at AOL and was VP of Service Delivery at Salesforce.com.
Based on the demo I saw, WeBot looks a little like Orb, another media sharing application I first saw a few years ago. WeBot chief's differentiator seems to be its focus on mobile devices, though like Orb, it seems to work best with Wi-Fi.
WeBot streams audio at the rate it was recorded in (so it maintains the quality of the original sound file). It also lets you access and share pictures. The company has plans to add video streaming and social networking in the future.
I look forward to playing with WeBot more over the holidays. Once I have some time on the clock, I'll let you know what I think.
