Applicant tracking system
Starts with the requisition. Stops at the accepted offer. Keeps the candidate pipeline.
THE TALENT OPERATING SYSTEM
What is a talent operating system?
A talent operating system defines a role once, from the business need it exists to serve, and carries that one definition through sourcing, hiring, onboarding and performance. Nu | Erraa is a talent operating system for startups: founders hiring while they run the company, and the first People hire carrying the whole function alone.
Why the definition has to survive the offer
About a fifth of what a hire costs goes to finding and choosing the person. The other four fifths (79%) lands after the offer, in ramp time, training and the hours your team spends teaching the new hire (Muehlemann & Strupler Leiser, Labour Economics, 2018).
An applicant tracking system is built for that first fifth. When the requisition closes, the reason you opened the role stays behind in the ATS, and onboarding starts from a blank page. A talent operating system keeps what the role has to deliver attached to the person you hired. Your onboarding plan, the first check-ins and the day-90 review all read from the page you wrote when you opened the role.
Talent operating system vs. ATS vs. HRIS
HRIS
Starts with the start date. Never stops. Keeps employee records, payroll and time off.
Talent operating system
Starts with the business need. Stays through day 90, then performance. Keeps the role definition and whether the hire is delivering against it.
How Nu | Erraa runs it
Nine stages: Define, Source, Interview, Decide, Handoff, Onboard, Manage, Check and Learn. Three agents do the work between the decisions that stay yours.
Amy: Turns the job you need done into a defined role, writes the posting, screens against that definition and stays with the hire through the first ninety days.
Aryah: Works from the role Amy defined and goes and finds people rather than waiting for applications. Sourcing is an optional add-on.
Sammy: Runs onboarding and support once the person starts.
What you learn at day 90 writes the next version of the role.
What it costs
$495 a month for up to 50 employees, $775 a month for 51 to 95. Sourcing adds $50 or $95 a month. Every user is included, setup and migration are included, and there's no implementation fee.
Questions founders ask
Do I need an HR team to use a talent operating system?
No. Nu | Erraa is built for founders who are the HR team right now, and for the first People hire who is the whole department.
Is a talent operating system the same as a talent management system?
No. A talent management system manages people you already employ: reviews, learning, succession. A talent operating system starts earlier, with the business need behind a role, and carries it through the hire and into performance.
How do I know if a hire is working?
Nu | Erraa runs a ninety-day check against the role definition you wrote at the start. Only 20% of organizations measure quality of hire at all (SHRM, 2025 Recruiting Executives Benchmarking).
