Popular online reviews site Yelp is going public.

Yelp Inc. said in a regulatory filing Thursday that it plans to raise $100 million in an initial public offering.

The amount of money Yelp is seeking in its IPO will likely change as its bankers determine how many shares should be sold and at what price. That process typically takes three to four months.

Yelp's underwriters include Goldman Sachs, Citigroup and others.

Yelp, based in San Francisco, says it generated $58.4 million in net revenue in the first nine months of this year. It booked a net loss of $7.6 million in the same period.
