RetailMeNot, the searchable coupon destination that was acquired by WhaleShark Media in 2010, wants to attract even more investment. The company has filed for a $230 million IPO, and SEC.gov has the S-1 form to prove it.

TechCrunch breaks it down the company's current state in a positive light:

RetailMeNot reports that revenues increased from $16.9 million in 2010 to $144.7 million in 2012. In the same period, net income increased from $2.3 million to $26 million, so the company appears to be profitable, and growing.

Does this mean that the competitive world of online coupons is about to get some added heat? Bet on it. But keep in mind, as Groupon's post-IPO adventures have shown, going public means weathering significant storms in the deal world.
