I turn operational debt into a company that can scale.

I build the operating systems, teams and governance tech founders need through growth, AI transformation and M&A.

The operating thesis

Scale breaks in the seams.

Finance data nobody trusts. People issues that consume the week. Processes that crack with every hire. Governance gaps that surface halfway through a deal.

That is operational debt. It builds quietly until it slows the company down—or becomes the deal risk. My work is to find it early, fix it for real and leave behind a business that runs better without heroics.

Where I step in

Advice is useful. A working operating system is better.

01

Scale the operating model

Put decision rights, ownership, finance, people and reporting in place before growth exposes the gaps.

02

Make AI operational

Turn AI from scattered experiments into workflows, agents and integrations that improve real delivery.

03

Get transaction-ready

Fix governance, controls and data before diligence—and keep the company moving through integration.

04

Build the function

Create the team, vendors, systems and management rhythm, then transfer ownership to leaders.

Selected work

Built in the room, not from the sidelines.

04COO & Co-owner

JUMP soft + Billdu

€5M revenue · 160K clients

Grew JUMP soft to 75 people and Slovakia’s fastest-growing tech company. In parallel, scaled Billdu into 24 countries; the company was later acquired by team.blue.

How I work

Embedded enough to see reality. Senior enough to change it.

I work beside founders and leadership teams—diagnosing the constraint, building the function and making the numbers visible. The goal is not permanent dependency. It is a stronger company with clear owners.

  1. 01See the whole system

    Metrics, ownership, talent, workflows, controls and incentives.

  2. 02Fix the real constraint

    Prioritize what changes company performance—not theatre.

  3. 03Build for transfer

    Create the team and rhythm leaders can run by numbers.

Operating track record

From startup zero to a public company.

Builder, acquirer, operator and advisor across software, AI, biotech and professional services in the US and Europe.

Founder of Nalu Sailing. RYA-certified skipper.

I also built a premium Adriatic yacht operation to run hands-off—from asset utilization and maintenance to suppliers and guest experience. Different environment, same principle: calm execution when conditions change.
