Synchronoss Technologies Inc. is exploring a sale, in the latest indication of brisk takeover demand for many software companies.

The Bridgewater, N.J., company is working with investment bank Qatalyst Partners on the possible sale, according to people familiar with the matter. As of Tuesday's close, Synchronoss had a market capitalization of about $1.8 billion, meaning that in a takeover it could be valued at well over $2 billion.

Synchronoss has drawn interest from a number of private-equity firms, the people said. As always in such situations, it is possible a deal for the company won't materialize.

Synchronoss produces software that allows customers to activate and perform other functions on wireless devices. Its customers include AT&T Inc., Verizon Wireless and Apple Inc., according to the company's website. Synchronoss, which was founded in 2000 and went public in 2006, had $457.3 million in revenue and $38.9 million in net income in 2014, both up significantly. Its shares have jumped 34% in the past year.

While private-equity deal making has been generally muted of late, software represents one corner of the market that has been lively.

Private-equity firms, which make acquisitions largely using borrowed money, have recently stepped up their buying and selling of software companies, which are able to take on relatively high levels of debt due to the recurring nature of their cash flows. Permira recently agreed to purchase data-software maker Informatica Corp., while Vista Equity Partners agreed to sell a controlling stake in security-software company Websense Inc. to Raytheon Co. Meanwhile, Bain Capital LLC agreed to buy security-software company Blue Coat Systems Inc. from fellow private-equity firm Thoma Bravo LLC.

And Genesys Telecommunications Laboratories Inc. is in talks with potential buyers for a deal that could value the call-center software provider at more than $3.5 billion including debt, The Wall Street Journal reported last month.

It is also a busy time for technology-company mergers. Just this week, chip maker Intel Corp. signed a $16.7 billion deal to buy Altera Corp. Last week, chip maker Avago Technologies Ltd. agreed to buy Broadcom Corp. for $37 billion, making it the largest pure-play technology deal on record.
