They have a consumer front end. It's quite decent, actually, and it's free. Go to Yodlee.com and sign up. But they apparently make most of their money by (a) licensing their back end to services like Mint, and (b) serving as a kind of OEM for banks, who put up Yodlee's software rebranded as a part of the bank's website.
If Mint is doing well, Yodlee is too. If Mint fails, Yodless will still have a diverse client base to support its business.
Wow - if Mint's growth doesn't impress you, then what has?
I felt their timing couldn't have been better. Their product matured as a recession hit and demand for money-saving financial services skyrocketed.
Mint just received $170 million. Yodlee did not.
Youtube was a huge money sink, and got a huge acquisition. Mint is, I believe at least, somewhat profitable, and only got $170M. The timing had a lot more to do with it than anything, but as a consumer, I'm a LOT more likely to give money to Mint than Youtube, and the YouTube founders are arguably a lot richer than the Mint founders.
What have the investors invested in ? A company that does not own its own core technology ?
