As the son of Hans Petri, Tim grew up with classical music and performing arts. During his education in economics, he worked on a project basis as a production assistant for companies such as Columns Classics, Opus Arte and EndeMol. After university Tim worked for the BBC as a researcher where he was involved in projects such as Cardiff Singer of the World and the Brecon Jazz Festival.
After returning to the Netherlands, he decided to focus on the sales profession. Through the banking industry he became specialised in document management technologies and worked as a Sales Manager, Sales Director and Co-founder of an organisation that provided various document management solutions. His interest was mainly in the innovative and software-based solutions.
In 2017, he decided to link his interests and skills to make (classical) arts available to the wider public in high quality digital formats. This has resulted in the founding of PetriArts Productions, where he is responsible as managing director.
