Gather

Gather is a video-calling platform set in customizable virtual spaces. Participants move avatars around digital offices, campuses, or event venues, with video/audio activating when avatars are near each other (proximity-based spatial audio). It supports large events with thousands of users across multiple maps. Features include interactive objects (whiteboards, shared TVs), breakout areas, and games.

For large, fully remote or hybrid teams, Gather fosters spontaneous interaction and social connection that traditional grid-based tools lack. It ranks for its unique approach to replicating office serendipity and building culture, making it excellent for all-hands, social hours, and onboarding, though it's less optimal for formal presentations.
