Private equity spent a decade buying up the software that runs your professional association. Personify, Higher Logic, Glue Up and a bootstrapped upstart called GroupApp show what is left of the market - and who owns it now.

Almabase, Hivebrite, Gravyty, Zapnito, Threado, Khoros and a pack of forum-software veterans are all selling one promise - a place your people gather that you actually own. The market got crowded, then it started eating itself.
