Meet the team
Our business thrives on the diversity of our talented people
We enjoy working with people who are performance driven with entrepreneurial determination, always evolving and learning and enjoy collaborative innovation.
Professional development begins with collaboration. The biggest steps are taken when we combine our knowledge and talents. Take Albert Hol (Project Manager) and Gerben Mulder (Consultant Management). They worked together on a project for a large retailer, where the billing process was renewed within Dynamics Finance & Operations using Azure Functions. The solution enables the retailer to process and invoice about 150,000 order lines quickly and accurately every day.
HSO has grown rapidly in recent years. This brings change, including in the company culture. To preserve the core of the old culture and embrace new values, a core group has developed a culture compass. Two members of the core group, Behnud and Otto, share their insights.
