MambaHR onboards your hires, runs payroll, handles time off and leave, and keeps you compliant in all 50 states — and only brings you the calls that need a person.
Switch from your current HRIS in a day
One-click import — people, pay history, time-off balances, documents. Nothing left behind.
Every HRIS needs people clicking the buttons. For every dollar spent on the system, companies spend six on the humans operating it. MambaHR is the operator.
“I was hired to build a great place to work. Instead I spend my days on paperwork.”
Head of People · 240 employeesWhy MambaHR
Same employee data. Same compliance. One difference: who actually pushes the buttons.
Built for people teams
HR is a people job. Mamba takes the admin so your team can do the work only humans can — the coaching, the culture, the hard conversations.
One place for everything
Six tools’ worth of work in one system that does it for you — hiring, onboarding, payroll, time off, performance, compliance. Your day shrinks to the decisions only you can make.

No new tool to learn. No portal to log into. Your team messages @MambaHR like a coworker — it reads the thread, checks your policy, does the work, and logs it.
Every action logged. One record of everything, everywhere.
Search MambaHRThe whole lifecycle
One agent runs the entire employee journey. Pick a stage — everything in it is handled, cited, and logged.
The role goes up, the best candidates surface, and the offer is signed before the competition even calls back.
What you get back
MambaHR hands the average people team 27 hours back, every single week — time that goes to the people, not the paperwork.
Payroll, onboarding, leave, and compliance — on autopilot.
The chasing, filing, and updating that filled your week — handled.
Paperwork, logins, and first week — ready before they arrive.
A full generalist’s workload, from $24k a year. Spend the difference on your people.

Stay compliant
Employment law changes almost every week. Mamba keeps up — and a human signs off on the big calls.
Loved by people teams
“By week two, Mamba had taken leave and onboarding off my desk completely. I finally spend my week on people, not paperwork.”
“Multi-state leave used to mean a week of emails with Legal. Now the answer comes back in seconds — with the law attached.”
“We switched on a Friday and ran payday Monday without a hiccup. Nothing fell through.”

Before you ask
Straight answers. No sales-call required.
We replace it — MambaHR becomes your system of record for people, pay, time off, and compliance. We pull everything from Gusto, Workday, Rippling, BambooHR, Namely, or ADP, and most teams are fully moved in a single day. Nothing left behind.
Live the next morning — a day of setup, not months of rollout. Day one we import your people data and you set your approval rules on one screen. Your team keeps working in Slack and Teams the whole time — most employees never notice the switch, except that HR got faster.
Yes. Encrypted in transit and at rest, role-based access, and a full audit trail on every change. Your data stays in the US, and we never train AI on it — that one is in your contract.
The sensitive calls — offers above band, terminations, anything high-stakes — always come to you first. Everything else is logged, reversible, and shows the rule it followed. You can override anything, and nothing happens without a trail.
You are always the employer — and MambaHR makes that easier, not riskier. Every answer cites the law behind it, federal and all 50 states, kept current. Anything ambiguous routes to a human before it happens.
Lean people teams at growing companies — two or three humans supporting hundreds of employees, buried in admin. If your HR team spends more time filing than talking to people, this was built for you.
