In my experience most meetups, unless they are specifically culled, super narrow (language, stack, hardware, industry specific etc...) or invite-only are typically made up of "wantrepreneurs," people who want you to sign an NDA to talk to them, grease-ball recruiters, a few rare independent people and the token public sector person trying to do tech-transfer or some other hare-brained initiative that is only good for the city/state/federal government.
