Imports from

MMambaHR

One-time import of people, comp, balances, reporting lines, and open pipelines. Not a customer list: these are the systems we read on day one.

You bought the software. You still do the work.

Every HR system needs people clicking the buttons. For every dollar spent on the system, companies spend six on the humans operating it. MambaHR does the clicking, so your people get that six back.

What you get back

Give your HR team their week back.

We estimate MambaHR takes about 27 hours of admin a week off a lean HR team, with the statute cited on every answer. That is our model, not a customer average, and we will publish real numbers as soon as we have them.

Before you ask

The questions every people leader has.

No sales call required.

Still have a question?
hello@mambahr.com
Do we replace our current HR system, or run alongside it?

We replace it. MambaHR becomes your system of record for people, time off, and compliance, and prepares every payroll change. We import from Gusto, Workday, Rippling, BambooHR, Namely, or ADP, or by CSV, and your data imports in a day.

How fast can we be up and running?

Most teams are live within a day of importing. Day one we import your people data and you set your approval rules in Settings. Your team keeps working in Slack the whole time, and most employees never notice the switch, except that HR got faster.

Is our people data safe?

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; both are written into our Data Processing Addendum, available on request.

What happens if it gets something wrong?

Sensitive calls (offers above your pay range, 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.

Are we still compliant, and who is liable?

You are always the employer. MambaHR makes that easier, not riskier. Every answer cites the law behind it, federal plus the rules for the states where you employ people. Anything ambiguous routes to a human before it happens.

Who is MambaHR built for?

Lean HR 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.
