An invite-only Slack community of 10,000+ experienced designers, developers, and product managers, including members from major companies.
The cross-functional mix (design, dev, and PM in one room) is the real differentiator: most design communities are design-only, and having product and engineering perspective in the same conversation surfaces friction points designers don't always see coming.
Best for designers who specifically want cross-functional perspective, not a pure design-craft critique space.
It's invite/application-based with a stated review period, so budget a couple of days before you're actually in.
A Slack community connecting product designers, developers, and managers.
