WHY ACHRIVE
I realized I was managing symptoms. Not the system.
For 13+ years I worked in HR across recruiting agencies, global enterprises, agile organizations and tech scale-ups. In every chapter I saw the same pattern: growth creates complexity faster than people systems can adapt.
​
Roles become unclear. Responsibilities grow faster than authority. Decisions slow down. HR becomes reactive. And smart people start spending too much energy navigating the system instead of doing their best work.
​
For a long time, I tried to fix it on the people side. Better hiring, better onboarding, better culture initiatives. Helpful? Yes. But never enough.
Then I realized: I was managing symptoms.
That's why I founded acHRive. I help founders and leadership teams build HR systems that create clarity, support sustainable growth and keep people effective as the organization scales.
HR that scales with growth, not against it.
WHERE I FIT IN
Three ways companies bring me in. Pick the setup that fits your situation.
Most start-ups and scale-ups don't need a full-time HR lead right away. They need senior HR expertise for a defined phase, a recurring rhythm, or a critical transition.
01 / Fractional
Your HR lead on demand
Senior HR support for 20–40% over a defined period. Ideal when your company needs structure, clarity and scalable HR without hiring full time.
02 / Strategic Partner
A senior sparring partner
For founders and leadership teams who need perspective on culture, leadership, people strategy, roles, decision making or organization design.
03 / Interim Bridge
Your temporary HR bridge
Senior HR presence during growth, change or transition. Ideal when things cannot wait until your next permanent HR hire is in place.
SERVICES
Start light. Scale what's needed.
Most engagements begin with a simple conversation. From there, we shape the work around your current stage, your priorities and what your organization actually needs.

ABOUT MARINA
Built HR from scratch through international growth, acquisition and post-merger integration.
I bring 13+ years of HR experience across recruiting agencies, global enterprises, agile organizations and tech scale-ups.
​
At 1plusX, a Swiss SaaS scale-up, I was the first dedicated HR hire and built the HR function from scratch as the company expanded internationally across CH, DE, FR, UK, Japan and the US.
I supported the organization through acquisition by TripleLift and post-merger integration.
​
What shapes my work today is simple: HR only creates value when it understands the business. That means understanding of cost structures, revenue drivers, and what it actually takes to run a company including clear roles, useful processes, strong leadership rhythms and people systems that grow with the company.
​
I know what tends to break at 30, 80 and 150 people. Not from a textbook, but from doing hands-on work. And today I help founders and leadership teams build HR that supports growth instead of slowing it down.
Also active as Lecturer in Human Resources Management at SIB Schweizerisches Institut für Betriebsökonomie, FSWI Fachschule für Wirtschaft und Informatik, and Art of Formation – Weiterbildung WBA AG.
HOW I WORK
Collaborative by design. Clear in purpose.
I help organizations create clarity where work has become complex, reactive or unclear. I ask before I conclude. I listen before I design. And I always explain why something matters, not only what needs to be done.
Grounded
My approach is calm, structured and kind, while staying clear and focused in content.
Human
I work with people, not just processes. Trust and integrity are the foundation of everything I do.
Honest
I tell you what I see, clearly and respectfully. Real progress starts with honest reflection.
Collaborative
I work with your team, not around them. The goal is to create solutions they understand, trust and can carry forward.
Practical
I design modern HR solutions that work in your reality, not just in theory.
