MambaHR vs TriNet
TriNet is a PEO with a service rep.
MambaHR is the department itself.
TriNet co-employs your team and assigns you industry-tailored benefits and an HR service rep. MambaHR is a different shape entirely — an AI HR department that does the administrative work directly, with no co-employment and no ticket queue.
Why teams switch
Three reasons, no fluff.
Keep your EIN 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 on top — no co-employment to unwind later.
The rep model has a queue. The agent 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 — and only routes the real judgment calls to your human.
No re-pricing your benefits to leave.
Because PEO benefits are bundled, switching off TriNet usually means re-shopping coverage. MambaHR is benefits-agnostic: keep your plans and broker, and let the agent administer enrollment and life events.
Side by side
The honest table.
Including the rows where TriNet wins — you’ll check anyway.
TriNet prices as a percentage of payroll with benefits baked in. MambaHR is flat — $14–$30 per employee, your coverage stays yours.
Do the math on pricing →TriNet is a capable PEO if co-employment and bundled benefits suit you. MambaHR is the AI department that does the work — your EIN, your benefits, no shared liability.
