Mint, an online personal finance tracker and tip application, officially launched yesterday at the TechCrunch40 Web startup conference, also taking home the top company prize and $50,000.

I’ve come across Mint in the past, but it’s never been open for public access. It is now, and I’ve opened an account and will be reviewing it soon.

Here’s the low-down on the services they provide:

– Account aggregation
– Expense tracking
– Account alerts
– Deal and account finders

Beyond the account and deal suggestions, it doesn’t sound much different than Yodlee. The interface, however, is 10x more Web 2.0 (if that’s a good thing …).

Suggesting new ways to save on credit cards, savings accounts and more is great.

I’ll have more on it soon, but for a quick review, Adena DeMonte at GigaOm calls it a “treat.”

I’ve been using the beta version for a few weeks now, and I am impressed with what the site has to offer. While competitors Geezeo and Wesabe are reasonably adequate for money management, Mint gets online personal finance right.

In order to add accounts to Mint, you must give them your user name and password for your various banks (similar to Yodlee). Although this may not seem totally safe, it’s a much easier way to aggregate account information than with Wesabe’s uploader (which I have since un-installed).
