When to use Mainder, Sésame, or both
When you need BOTH
- Spanish SMB with active recruiting AND employee HR ops needs.
- You already use Sésame for time tracking + payroll but the recruiter side is manual.
- You're growing hiring pace and need AI-native sourcing + structured pre-screening without disrupting your Sésame setup.
When Sésame alone is enough
- Very low hiring volume (1-3 hires/year) with manual sourcing acceptable.
- No need for AI-native sourcing or autonomous 24/7 hunting.
When Mainder alone is enough
- You're a recruiting agency placing candidates at client companies — no internal HRMS needed.
- You use a different HRMS for your internal team.

Is Mainder a Sésame replacement?
No. They're different layers. Sésame is the HRMS for Spain SMB employees (time tracking, leave, payroll, performance); Mainder is the AI-native ATS+CRM+Sourcing for recruiters (sourcing, screening, communication, hire). Use both together — Mainder feeds hired candidates into Sésame via webhooks.
Does Mainder integrate with Sésame?
Yes — Mainder Business+ ships webhooks outbound that fire on hire events. Configure your Sésame endpoint to receive hire events and create the employee record automatically. Setup typically 1-2 days with white-glove support.
I'm using Sésame — why add Mainder?
Sésame is HRMS, not ATS. If you're growing hiring volume and the recruiter workflow is manual, Mainder adds AI-native sourcing (NL search + autonomous AI Hunt 24/7 across billions of profiles), Killer Questions structured pre-screening (7 types), Unified Inbox 5 channels, and MCP Server for LLM agents.
I'm a Spanish recruiting agency — do I need Sésame?
Probably not. Recruiting agencies place candidates at clients, not employ them internally. Mainder alone covers the agency workflow end-to-end with multi-tenant Career Sites per client. Sésame is needed only if you employ staff internally.
What other HRMS does Mainder integrate with?
Mainder Business+ webhooks integrate with any HRMS accepting webhook events — Sésame, Factorial, Orbio, Personio, BambooHR, HiBob, Workday (via middleware). Generic webhook model with white-glove configuration.
