Straight from the Juice Pitcher event in San Francisco, Ca., hosted by Vator.tv and The Funded, here's the list of the first five winning presenters.

These companies were chosen mainly based on peer voting held on the Juice Pitcher competition where more than 130 companies participated and more than 3,000 votes were cast.

Viralogy is based on the idea of "Personal Branding" across the Web.  It refers to itself as the "Alexa for People."  The startup has built a way for users to measure how influential they are on the Internet.  It likes to be thought of as an analytics tool for people, not Web sites.  So instead of trying to measure your specific profile page, say for example, your Twitter profile, Viralogy measures your presence across the entire social Web.  It uses metrics from personal blogs, votes, Twitter, Facebook, LinkedIn, YouTube and Pagerank to score users.  People interested in finding out where their influence stands can use Viralogy to compare and see their rankings against other users. 

IDNTITI is a free social rating tool that allows users to add questions and parameters to a questionnaire or feedback form. The startup says this feature allows users to get precise and objective feedback from the entire community of users. In essence, similar to Viralogy, and other services like Rapleaf, IDNTITI is a reputation tracker. Users can invite their communities to rate companies, schools, colleges, restaurants etc and then filter data based on demographics or whatever may be important to that user.  Right now, IDNTITI's product is available as a Facebook Application.  It also offers premium services.

Looking to make money off an unused vehicle sitting in your garage?  Try RelayRides, a peer-to-peer car sharing marketplace. It's like Zipcar with a P2P element. The company, which will start in the Baltimore area first, enables its users to post their cars for rent on its site. The startup says the average person only drives their car for 66 minutes per day, so why not rent it out?  Its infrastructure enables car owners to set their own prices and lengths of rentals, RelayRides takes a 15% cut of transactions.   When a renter borrows a car, gas and insurance are included in the fee. This is good news for RelayRides as insurance can be a significant chunk of its expenses. RelayRides says car owners can turn their vehicles from an expense into a cash machine, with an average profit of approximately $3,550 annually. RelayRides says it hopes its rental prices will be more affordable to alternative carsharing services. 

Tribevibe is looking to track and measure the impact of content across the social Web.  The company offers a single place to check out how your content is being seen, shared, linked and talked about.  Still in stealth mode, Tribevibe says it will launch as a free service with its target market being the 10% of Internet users that produce most of the content across the Web.  The startup says more than 3000 people have signed up for its initial alpha program, if interested you can sign up here.
