Right now an entirely separate platform, but the original idea was an integration with Zoom. Unfortunately their API doesn't support breakout room management yet (https://devforum.zoom.us/t/breakout-rooms-api/4255/111) so the idea was to build it entirely separately, get some validation/learnings, and then integrate with Zoom when ready.
In terms of mingle-naturalness, right now it's set so the organizer just says how big the mingles should be and how long they should last. So from a user's side, you're in a group with two random people (from the company/larger group) for 5 minutes, then cycle into a new mingle with two other random people, rinse and repeat. Somewhat like speed dating, you don't have any say over who you're mingling with, but it is time constricted.
