Word from the team


Experience, Excellence & Empathy

The creation of ACO is the culmination of its founders' 20 years of experience in the field of IT and financial consulting in Luxembourg. a Luxembourg specialist in software development (fixed-price & time and materials) and GDPR compliance joined the staff of ACO.

At the heart of ACO's engine is 'satisfaction' that of our consultants, which leads to that of our clients. Respecting and promoting human values, as well as the professional standards that are dear to us, explain our vigorous growth since 2021.

ACO provides its institutional, private and public clients with expert consultants in I.T.GovernanceRegulatory Compliance and Sovereign Artificial Intelligence.

This is how the Associates & Managers are personally responsible for the recruitment, training and monitoring of consultants and/or development experts who work with our clients: ACO thus ensures a remarkable match between the need for Human Capital & AI expressed by its clients and the operational skills offered.

This is also why we have maintained a short and local decision-making process, offering our clients and collaborators valued responsiveness in any circumstance.

ACO's DNA


FUN WITH PURPOSE

Serious… without taking ourselves too seriously. This is the mindset with which ACO fosters the development of its teams.

The goal? To enjoy collaborating not only with our clients during the critical missions they entrust to us but also between ACO Consultants and Managers!

With a young and dynamic team, whose average age is under 35, we understand that the quality of life for our teams is essential to satisfying both them and our clients.

That's why we regularly organize technical workshops with our 'Tech Leads', events, and fun activities, ranging from themed afterworks to original team-building days/trips, to strengthen bonds and inject positive energy into daily life. This friendly and stimulating atmosphere helps us collaborate more effectively, innovate, and deliver high-quality work for our clients.

Joining our team means choosing a unique balance: professional excellence in a warm and motivating environment.

At ACO, you can build your career while enjoying an inspiring and human-centric work environment.

Great Place To Work®


ACO RECOGNIZED

The “GREAT PLACE TO WORK” label is a prestigious distinction that evaluates the quality of working life within companies. It is based on two main criteria: feedback from employees via an anonymous questionnaire, and an in-depth analysis of managerial practices and initiatives implemented by the company. The label rewards companies where trust, pride in belonging, and conviviality prevail.

To be recognized for two years in a row testifies to ACO's collective commitment to creating a fulfilling and caring work environment.

We extend our heartfelt thanks to all our employees, whose commitment and shared values make this recognition possible. Together, we are proving that a successful company can also be a great place to work.
