Meet the team

Nice to meet you! We are Team Chordify and we are dedicated to making the world live its music. How do we do that?

We work in multi-disciplinary teams, where everybody can play their part in the fast-growing big band that this company is.

Abel Pruim

Abel learns by doing. His job experience as an SEA specialist has bolstered his online marketeering skills, which he now uses to make sure musicians are able to find Chordify in the Google Play Store and App Store. As it happens, it was this combination of music and technology that drew him to Chordify in the first place.

Andrea de Pater

HR Officer

Andrea’s passion is to inspire, support and facilitate people to use their talents, and do the work that energizes them.

Ans de Nijs

Front-end Developer

Being a fan of Pikachu doesn’t really help Ans with her tasks as a front-end developer. Luckily, she doesn’t need any help with that, because she has a master’s degree in information studies and a bunch of experience under her belt. If you hear Disney tunes coming from the kitchen, it might be Ans sneaking in a little karaoke practice.

Arjen Sol

Bas de Haas

CEO \\ Co-Founder

Bas wrote the first version of Chordify’s algorithm and after finishing his doctoral thesis in computer science in 2012 he didn’t want his work to get lost in a dusty closet with other dissertations, so he put together a team of music enthusiasts to create Chordify. Bas is passionate about music, playing guitar, new technologies and entrepreneurship.

Gijs Bekenkamp

COO \\ Co-Founder

Strategist, pace setter and co-founder Gijs spent ten years of his life playing drums in a band with Bas. He doesn’t play anymore, but he still loves the beat of KPI crunching in the morning.

Herman Blaauw


Our bookkeeper Herman has a passion for numbers which comes from the drive to make a company thrive. He is also a vinyl guy who loves his rock and electro albums.
