That whole category solves the moment of meeting. Algorithmic matching, curated dinners, RSVP funnels, paid event discovery. They are useful, and they are not what Pondid is.
Those apps end when the event does. Pondid begins where they leave off. The point is not getting strangers into a room once. The point is the steady accumulation of presence in a place over time, until the strangers become Regulars. They solve the moment of meeting. Pondid is about what happens next.
