Why HR in a scale-up breaks at the same points every time
In a scale-up, HR demand does not grow gradually. It jumps. A closed round means a hiring plan of 40 or 80 people within a year, and the founder who used to write every offer letter is suddenly running a company where three people a week start and nobody owns the process. The informal setup that carried the team to 40 employees, a shared drive with contract templates, a Notion page for onboarding, an office manager who also does payroll handover, does not fail loudly. It fails quietly: a probationary period that nobody tracked, a contract with a clause copied from a different country, a new manager who has never held a performance conversation.
German employment law adds a second layer that many founders, especially in English-speaking teams, meet for the first time. From five employees onwards, the workforce can elect a works council (Betriebsrat), and once it exists, a whole set of decisions, from working-time rules to the HRIS you roll out to the AI tools your recruiters use, become subject to co-determination under the Works Constitution Act (BetrVG). A scale-up that learns this during its first restructuring pays for the lesson twice.
The third factor is expectation. Scale-up teams expect digital processes, fast answers and AI in everyday HR work, not paper forms and a two-week wait for a reference letter. A classic HR generalist without build-out experience is quickly overwhelmed by the combination of speed, legal weight and expectation. That combination is exactly what I take on.
Typical HR triggers in software scale-ups
Three moments where, in my experience, founders and COOs pick up the phone:
The round has closed
The hiring plan says 60 people in twelve months. There is no HR lead, no structured interview process, and every contract is still written by hand. The clock is already running.
The first works council
An election notice appears on the kitchen wall. Nobody in leadership knows what the works council may decide on, what it may not, and how the first hearing on a termination works.
Systems that do not talk to each other
Payroll runs on one tool, absences on another, contracts in a folder. At 120 employees the HR generalist spends half the week reconciling data instead of doing HR.
Which role fits a scale-up
Most scale-up engagements start with HR Operations: processes, systems and payroll governance that have to keep up with growth, without the company needing full-time leadership of an HR team that may only be two people. That is the role in which I cut manual HR administration from 30 to 5 hours a week at an international software company, through process and system work rather than headcount.
If there is no HR lead at all and the company is past roughly 100 employees, the gap is bigger and the fit is Interim HR Manager: full HR ownership for three to eighteen months, including the works council, the managers and the hiring plan. Companies that need senior direction but not five days a week choose Fractional HR on one or two fixed days. Switching between the models is possible when the situation changes, and it often does in a scale-up.
A case from a past role
At an international software company, HR administration had grown with the company and nobody had rebuilt it: reference letters, contract changes, absence tracking and onboarding paperwork took around 30 hours a week of manual work across the team. Instead of adding a person, I rebuilt the processes, introduced an HRIS with clean data and automated the recurring documents. The same work then took about five hours a week, and the time went back into hiring and manager support. The full write-up, anonymised, is under Cutting Manual HR Admin from 30 to 5 Hours a Week.
The other side of scale-up life I know from a software company: a reorganisation across nine countries in three months, carried out in full compliance with employment law and co-determination. The project format for that situation is Restructuring and Social Plan.
How an engagement runs
30 minutes, directly with me. You describe headcount, plan and what exists today. Within one working day I say whether and from when I can help.
Contracts, open roles, onboarding, tools, works council status, deadlines nobody is tracking. Day-to-day HR keeps running from day one.
Templates and process for hiring, structured onboarding, HRIS with clean data, AI routines for job ads and reference letters, works council brought in early.
Documented processes, open items with status, and if wanted the permanent HR lead recruited and onboarded by me.

Questions from scale-up founders and COOs
Do you know the HR systems scale-ups typically use?
Yes. Selecting and rolling out an HRIS is part of my HR Operations work, including at an international software company where manual HR administration fell from 30 to 5 hours a week. Which system fits depends on headcount, countries and payroll setup, not on what the last company used.
Our first works council is forming. Can you help?
Yes. A works council (Betriebsrat) that forms for the first time needs an employer who knows the rules before the first hearing. I have set up that first working relationship more than once, and it is easier to get right at the start than to repair later.
We are mostly English-speaking. Is that a problem?
No. Most of my international teams were led in English. Employment contracts, works council documents and anything that has to hold up under German law stay in German, and I handle both sides.
Can you start before the next funding round closes?
Usually within two weeks of being engaged. If the round is the trigger, the sensible order is to have the contract templates, onboarding and hiring process ready before the money arrives, not after.
What happens if we later need to reduce headcount?
That happens in scale-ups more often than founders expect. A restructuring under German law follows fixed steps, works council involvement included. I have delivered a reorganisation across nine countries in three months at a software company and describe the approach under Restructuring and Social Plan.
Full-time interim or a few days a week?
It depends on the size of the gap. A company at 150 employees with no HR lead needs full-time. A company at 60 with a capable HR generalist usually needs one or two fixed days a week of senior direction. We settle that on the call.
