Two tech companies made strong Wall Street debuts today, another positive sign for Triangle businesses hoping to pull off their own IPOs.

SS&C Technologies, a Connecticut software company, and Meru Networks, a California maker of Wi-Fi equipment, saw their shares rise today after selling stock through initial public offerings.

That bodes well for companies such as Lulu, the Raleigh-based online book publisher, which is preparing for an IPO in Canada, and Cary-based SciQuest, which filed plans for a U.S. IPO last week.

Motricity, a wireless company that moved its headquarters to the West Coast from Durham, also has filed IPO plans. That company still has offices in Durham and employs about 100 people locally.
