MambaHR vs TriNet
TriNet is a co-employer with a service rep.
MambaHR is the department itself.
TriNet is a PEO: it puts your staff on its own tax ID and assigns you bundled benefits and an HR service rep. MambaHR is a different shape entirely: the AI HR department that does the administrative work directly, with no co-employment and no ticket queue.
Why teams switch
Three reasons teams switch.
Keep your own tax ID and your independence.
TriNet's PEO model puts your people on its tax ID and shares employer liability. MambaHR leaves your employment relationship untouched and runs the admin work, no co-employment to unwind later.
The rep model has a queue. MambaHR does not.
TriNet assigns a service rep for the complex questions. MambaHR answers in Slack the moment the question is asked: leave eligibility, multi-state rules, classification. Only the real judgment calls come to you.
No re-pricing your benefits to leave.
Because PEO benefits are bundled, switching off TriNet usually means re-shopping coverage. MambaHR does not administer benefits: keep your plans and broker, and they keep running them.
