Workspaces with owners and end-users, per-user permissions that AI agents must respect, and SAML/SCIM at the top tier prove a second person has a defined place. But nothing shows a shared timeline, dependency, workload or guest view — '100+ products' is a slogan, not a feature list — so I can't credit team-level planning that isn't evidenced.

Assignments, a team capacity view that shows who's free and who's overloaded, a RAID log that structures risks and dependencies, granular permissions, and customer portal accounts for client involvement — team-level planning is clearly first-class, positioned to run 10 to 500 people on the same platform. I found no public information on lightweight guest access outside the customer portal model, so I stop just short of the top.
