Tibco is just the latest enterprise software firm to go private, following in the footsteps of BMC Software and Compuware. The latter company's agreement earlier this month to be sold to private equity firm Thoma Bravo for $2.5 billion marked the largest tech buyout of the year until Tibco's announcement, Bloomberg reported. And the deal-making may just be getting started. Daniel Ives, an analyst for FBR Capital Markets, predicted on Monday that slumping IT spending and heightening competition would drive more competition in the enterprise software space.
