CHALLENGE
As a PE-backed tour operator, Berge & Meer was facing significant transformation pressure. A historically grown and fragmented system landscape, combined with an outdated ERP system, limited forecasting capabilities, reporting quality, and overall IT controllability.

Defined an ERP modernization roadmap (Microsoft Business Central) aligned with the investment horizon
Rebuilt the data warehouse and analytics architecture on Microsoft Fabric
Developed a 3-year AI-First strategy with prioritized ROI-driven use cases
Implemented board-level reporting and clear IT governance structures
Consolidated vendors and optimized key technology contracts

Revising the strategy and reorganizing into a product-oriented organization together with the CEO and Head of Product
Reactivating the OKR organization, upskilling employees, and preparing for and conducting 5 security audits per year

CHALLENGE
Temedica GmbH, a digital health company, faced the challenge of responding quickly to Series B investments and delivering critical projects with pharmaceutical companies. This included scaling up from 18 to 32 employees in just four months, as well as obtaining Software as a Medical Device (SaMD; ISO 13485) certification.
SOLUTION
Taking on responsibility as Interim Director of Engineering
Scaling the teams from 18 to 32 employees, including forming agile teams to accelerate product development and delivery
Successful development and certification of the SaMD solution
Sustainable improvement in project execution efficiency within the highly regulated health/pharma market
RESULT
“I know Martin for many years already. Never had a chance to really collaborate ‒ but then ... an opportunity showed up when I needed an interim manager. [...] He took care of the whole software development department, filled with young and demanding characters, both internal and in various near shore setups. He kept people motivated, engaged and was looking after their concerns, acting like a great servant leader and evolving into a trusted advisor and coach for many of the wonderful Temedicans in Software Development. Aside from the joy of leading people, Martin supported me in various project activities, took over when needed and assisted teams to deliver their promised outcomes. I can highly recommend Martin if you're looking for a senior manager in interim situations (I couldn't manage to convince him to become a Temedican ...). I would work with Martin again ‒ any time.”
