In this week's episode, Brian Singerman, a venture capitalist at The Founders Fund, shares his opinions on two emerging companies that enable people to share rich-media content in a much easier way. We look at Drop.io and Xoopit. We start with Drop.io, which raised $5-plus million from RRE Ventures and Draper Fisher Jurvetson. Drop.io is an easy-to-use platform that enables users to share rich-media files, like videos and photos and even voice messages, to a private group. It's really easy and has great UI. From my tests, this site rocks when it comes to sharing files. It's a lot easier than Box.net. And, the upload time is faster.

We also looked at Xoopit, which raised $6.5 million from Accel Partners and Foundation Capital. Xoopit makes your inbox come alive. Xoopit is about finding the media and helping you generate social experiences with people, according to Bijan Marashi, Xoopit's co-founder and CEO. Basically, Xoopit makes your Webmail feel a lot more like Facebook, and a lot less like Outlook.

In this Vator Box, we discuss competitors to both companies. For instance, Drop.io competes with Box.net, Yousendit, and Pando. We also discussed how Xoopit differentiates itself from competitors like Xobni and ClearContext. 

The bottom line is that Brian and Ezra agreed on betting on one company. I chose the other as my bet. You'll have to watch to see which one we chose.
