Multi-user structure is proven — workspaces with owners and end users, a permissions model, SAML SSO and SCIM provisioning — but not one shared planning surface is evidenced: no timeline, no workload view, no dependencies, no comments, no guest access. '100+ products' is a slogan, not a feature; per the evidence, planning beyond a shared workspace is invisible.

Task assignment, a RAID log that explicitly tracks dependencies, and a capacity view showing who is overloaded are named modules, and customer-portal accounts plus granular role permissions give clients a defined, bounded place in the work. Planning, workload, permissions and client involvement are all evidenced across a stated 10-to-500-person span; what we found no public information on is comment threads or in-task discussion.
