Credit Karma now has 60 million users. Yes, that zero is supposed to be there.

And the company, which gives out free credit scores and generates revenue from selling lending leads, is adding 1 million to 2 million users — which the company calls “members” — per month, a Credit Karma official told an investment banking audience yesterday.

Credit Karma, consistently one of the most popular financial mobile apps, was founded in 2007 and has raised $368 million of venture funding to date, according to Crunchbase.

These eye-popping numbers put Credit Karma squarely in competition with LendingTree in the credit leads space. And that competition will only intensify: Credit Karma is preparing to begin offering mortgages to its “members” soon. Obviously, mortgages represent a massive opportunity for Credit Karma, and the additional product takes dead aim at LendingTree’s most prominent vertical. More than half of LendingTree’s overall business comes from the mortgage sector. Credit Karma’s largest sector today is credit cards.

Credit Karma is also considering a move into student loan refinancing, and possibly personal insurance, although insurance is less of a certainty.

Credit Karma today facilitates originations of student loans, business loans, auto insurance, auto loan refinances and personal loans, which has been a hot space in online lending over the last couple of years. It counts among its clients Capital One Financial Corp., Barclaycard, JPMorgan Chase & Co., and Citigroup.
