Mainder + Factorial: AI-native ATS for recruiters that feeds Factorial HRMS
Mainder is the AI-native ATS, CRM and Sourcing platform for recruiters — three categories rebuilt with AI at the core. Factorial is the HRMS for employees — payroll, time tracking, performance reviews, employee records. They're not the same layer. Use Mainder to find, screen, and hire the right candidate with proprietary AI engine (2 sourcing modes, Unified Inbox 5 channels, Killer Questions). Use Factorial to manage that employee post-hire (HR ops, payroll, leave). Integration via webhooks (Business+) handoffs the hired candidate from Mainder to Factorial.

Mainder + Factorial, not Mainder vs Factorial: these are different layers of the recruiting + HR stack. Factorial is the HRMS for employees post-hire — payroll, time tracking, leave management, performance reviews, employee records. Mainder is the AI-native ATS+CRM+Sourcing for recruiters pre-hire — find candidates via proprietary AI engine (NL search + autonomous AI Hunt 24/7 across billions of profiles), screen with structured Killer Questions, communicate via Unified Inbox 5 channels, and run multi-tenant white-label Career Sites per client or brand. They integrate via webhooks (Mainder Business+) to handoff the hired candidate's data into Factorial for HR operations. Use both together for the full pre-hire → post-hire lifecycle. From €24/seat Starter, €69/seat Business for Mainder.
Layer comparison: where Mainder ends, Factorial begins
| Lifecycle stage | Mainder (recruiter-side) | Factorial (employee-side) |
|---|---|---|
| Sourcing (find candidates) | ✅ Native — proprietary AI engine, 2 modes (NL + AI Hunt 24/7) | ❌ Not an ATS sourcing layer |
| Application + tracking | ✅ Native ATS workflow | ❌ Not an ATS |
| Pre-screening (structured questions, scoring) | ✅ Native — Killer Questions 7 types + AI Scoring | ❌ Not an ATS |
| Candidate communication | ✅ Unified Inbox 5 channels (Gmail/Outlook/IMAP/LinkedIn/WhatsApp) | ❌ Not candidate-facing |
| Hire decision + offer | ✅ Native | ❌ Not part of HRMS |
| Employee onboarding | ⚠️ Hand-off via webhooks | ✅ Native (Factorial strength) |
| Payroll | ❌ Not in scope | ✅ Native (Factorial strength) |
| Time tracking + leave | ❌ Not in scope | ✅ Native (Factorial strength) |
| Performance reviews | ❌ Not in scope | ✅ Native (Factorial strength) |
| Employee records / HR ops | ❌ Not in scope | ✅ Native (Factorial strength) |
Integration model: Mainder Business+ ships webhooks outbound — when a candidate is hired in Mainder, webhook fires to your Factorial instance to create the employee record. Recruiter pipeline ends; HR ops pipeline begins.
When to use Mainder, Factorial, or both
When you need BOTH
- Spanish/EU SMB or mid-market company with both active recruiting AND employee HR ops needs.
- You want AI-native recruiting (Mainder) feeding into your HRMS of record (Factorial) — clean handoff at hire.
- Your team uses Factorial for payroll + time tracking + performance today but lacks AI-native recruiting capability.
- You're growing your hiring pace and need autonomous sourcing + structured pre-screening + Unified Inbox without disrupting Factorial.
When Factorial alone is enough
- Your hiring volume is very low (1-3 hires/year) and you do all sourcing manually.
- You don't need AI-native sourcing, autonomous 24/7 hunting, or structured pre-screening today.
- Your recruiter side is fully manual and you don't see that as a constraint.
When Mainder alone is enough
- You're a recruiting agency — hired candidates are placed at client companies, not employed by you. No HRMS needed.
- You use a different HRMS (Workday, BambooHR, HiBob, Personio) for internal HR ops.

Is Mainder a Factorial replacement?
No. They're different layers. Factorial is the HRMS for employees (payroll, time tracking, leave, performance, employee records); Mainder is the AI-native ATS+CRM+Sourcing for recruiters (sourcing, screening, communication, hire). Use both together — Mainder feeds hired candidates into Factorial via webhooks.
Does Mainder integrate with Factorial?
Yes — Mainder Business+ ships webhooks outbound that fire on hire events. Configure your Factorial endpoint to receive hire events and create the employee record automatically. Setup typically 1-2 days with white-glove support.
I'm using Factorial — why add Mainder?
Factorial 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, multi-tenant Career Sites per brand, and MCP Server with 14 native tools for LLM agents.
I'm a recruiting agency — do I need Factorial?
Probably not. Recruiting agencies place candidates at clients, not employ them. Mainder alone covers agency workflow end-to-end with multi-tenant Career Sites per client. Factorial 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 — Factorial, Sésame, Orbio, Personio, BambooHR, HiBob, Workday (via middleware). Generic webhook model with white-glove configuration.
