TechCrunch by Michael Arrington:- Intuit has acquired the free online personal finance service Mint, we’ve confirmed from a source close to the deal, for around $170 million. The deal should be announced in the next few days.

This is a terrific exit for Mint, which first launched two years ago at TechCrunch50. Mint took the top prize at that event and has been growing fast ever since. Their last round of financing valued the company at $140 million.

In all, Mint has raised $32 million over three venture rounds.

Earlier this year Mint and Intuit had a humorous clash over Mint advertising claims of gaining 3,000 new users a day and jumping from 600,000 to 850,000 users in a matter of months. Intuit sent a letter to Mint demanding an explanation for this apparently inconceivable feat, which we obtained and printed here.
