The Top 3 personal finance startups from TechCrunch 50

For the past three years, startup companies have fought to present at TechCrunch 50, a conference held by popular tech website TechCrunch.com, in order to win a $50,000 grand prize. Companies demoing wares were as varied as a Penn & Teller iPhone app to the next big social media website. Mixed in with this varied lot are several cool companies that will make it easier to buy and sell used cars, earn money from endorsements and conduct gift card auctions.

Keep in mind that some of these companies haven't completely launched yet, so when you visit them you may have to ask for access by providing your email address. Doing so will let the company give you early access to these new and exciting services before the general public. When the companies launch in the coming months, WalletPop will bring you more details and information about how these services will affect your life.
