This is a completely different universe from VC, Tiger, Figma or even the public markets. Software companies like this (low growth, high cash flow) got absolutely eviscerated in the public markets over the last decade so they would never consider that. And TIBCO is about 20 years out from the growth they needed to attract VC money or money from Tiger. Won't bother with the Figma exit comparison. The universe of buyers after this company will either be a mega-club deal with a mix of PE firms, pension funds, sovereign wealth funds, etc. or one of the hulking B2B software giants I had mentioned.
No matter how you want to couch it, PE firms got away with this one. They're content to grow the topline 4-8% per year and cash flows 10-15% (the real metric that matters because the company isn't growing enough to ever be valued on a revenue multiple but will be valued on an EBITDA or FCF multiple). At roughly 15,000 combined headcount today, I'd expect that number to be under 10,000 in 24 months.
