Mission

The problem we're solving

HR teams are drowning. Not in people work — in admin. Leave requests, onboarding checklists, payroll updates, policy questions. The same tasks, repeated thousands of times, consuming 40% of an HR team's time.

The existing tools just organized the busywork into prettier dashboards. Nobody actually did the work. Until now.

MambaHR is the first HR agent that doesn't just track tasks — it completes them. Autonomously, accurately, and with full policy verification built in.

Values

What we believe

01

Autonomy over automation

We don't build dashboards with more buttons. We build an agent that does the work — so your team doesn't have to.

02

Accuracy is non-negotiable

HR decisions affect people's lives. Every output is verified against encoded HR policies. Not a confident guess — an auditable answer.

03

Research-first

We publish benchmarks, build proprietary datasets, and file patents. MambaHR is a lab, not a wrapper.
