MambaHR vs Justworks
Justworks gives you a support queue.
MambaHR gives you the answer.
Justworks is a PEO: it puts your staff on its own tax ID, and you lean on its support reps for the hard questions. MambaHR is the AI HR department: the work gets done in Slack, no co-employment, no shared liability, no waiting on a ticket queue.
Why teams switch
Three reasons teams switch.
No co-employment. Your company, your own tax ID.
A PEO puts your employees on its own tax ID and shares legal liability for them. MambaHR doesn't touch your employment relationship, you stay the employer of record, and MambaHR handles the administrative work.
Answers in seconds, not a support queue.
Justworks routes the hard questions to a human support team. MambaHR answers in Slack instantly, with a citation: family leave (FMLA) eligibility, final-pay timing, pay transparency. Only the genuine judgment calls come to you.
You keep your benefits broker.
PEOs bundle benefits into the package, so leaving means re-shopping coverage. MambaHR does not administer benefits, so your broker and your plans stay exactly where they are.
Side by side

See pricingJustworks is a good PEO if you want bundled benefits and a support team to call. MambaHR is what you turn on when you want the HR work itself done, without handing over your employment relationship.
