Why startup teams choose Mantis.
Zero hand-holding
Senior QA engineers take ownership from day one. You won't be writing test plans, triaging tickets, or onboarding new hires every quarter.
Integration in 2–3 days
We plug into your existing stack, repos, and rituals fast. Most teams see structured QA running by the end of the first week.
Cost-efficient vs. in-house QA
Get senior QA coverage without the salary, recruiting, and ramp-up cost of building a team from scratch — and without the lock-in.
Scales with your team
Add coverage as you ship more, pull back during quieter cycles. We adjust to your release cadence, not the other way around.
