At McKinsey & Company’s Amsterdam office, Pieter worked on strategic, operational and organization projects for international clients before joining Rotterdam based shipping company Anthony Veder in commercial and project management roles.
Having seen many different companies, varying in size and industry, it struck Pieter that many organizations struggle with adapting their organization in changing environments. Pieter is convinced that Holacracy’s focus on organizing around work instead of people and powering individual employees with freedom and responsibility will support organizations to cope with changing environments.

Anna Swinkels is a star in organizing and bringing people together. She studied to become a Montessori primary school teacher and studied Office Management for a couple of years. She discovered a common theme, her love for supporting people and helping them to improve themselves.
During the five years Anna worked in childcare, she had many different roles from the receptionist and human resources to planning and childcare worker. She learned how to be flexible and multitask, always with a smile! After these years she made the switch to commercial business. SparkOptimus was in 2013 a fast growing consultancy agency with ten employees. Anna has seen the company grow to fifty employees and was intimately involved during this explosive growth period. Her central role was that of personal assistant to managing partners.
At OrganizationBuilders, Anna has many different roles, from Website administrator and IT support to Event organizer and Culture Amplifier. With her pragmatism, attention to detail and openness, she helps OrganizationBuilders grow.
You can run into Anna on a Salsa party, behind a sewing machine, traveling with her husband, with her nose buried in an English thriller book or laughing at Van Kooten and De Bie.
