AFAIK, it's Stark Industries. Unless you mean something else.
Stark Industries was founded by Isaac Stark, Sr. in the 19th century and later taken over by Howard Stark and then by his son Tony, after his death. Over the years, through bankruptcy, Tony's "death", Tony's return and hostile takeovers, the company has gone through many name changes including Stark International (later Stane International), Stark Enterprises, Stark/Fujikawa and Stark Solutions.

It had even more names, I believe, but never was known as "StarkCorp".
