Private equity firm Thoma Bravo announced Thursday that it's completed its $395 million acquisition of internet and mobile cloud testing and monitoring company Keynote Systems.

As a result of the purchase, Keynote stock will no longer be publically traded, Thoma Bravo said. Its past ticker symbol was KEYN.

The newly minted division of Thoma Bravo will remain headquartered in San Mateo, Calif.

The company also announced that retiring CEO Umang Gupta will transition the CEO role to software and technology industry veteran Jennifer Tejada. Most recently, Tejada was an executive vice president and chief strategy officer at enterprise software company Mincom.

"As businesses increasingly shift core customer interactions and transactions to mobile and online, performance monitoring for those platforms is key," said Tejada in a press release. "This transaction will allow us to continue to innovate for our customers with the increased flexibility of a private company."

Thoma Bravo recently bought Intuit's financial services division in a deal valued at more than $1 billion.
