Good Technology Inc. was on to something big when it developed software that allows employees to securely access work files from their personal smartphones. The Sunnyvale, Calif.-based company’s suite of applications routes encrypted data through a cloud server and behind an employer’s firewall, all while keeping personal information separate from work data.

Demand for the company’s technology has skyrocketed as more people than ever tote smartphones and work remotely. Good Technology has nearly 800 employees — twice as many as when general counsel Ron Vaisbort joined in 2011 — and is rumored to be edging toward an initial public offering this year.
