Sijbrand van der Mast
Investment Director
Sijbrand was born in London and spent much of his primary school years there. He went to secondary school in Bussum and studied Economics in Groningen.
He started his career at Pelargos Capital in The Hague, an investor in Japanese listed companies. He then moved to Liberty Global, the parent company of VodafoneZiggo, where he worked for years on strategy and corporate development. There he found the combination that still drives him: making a good plan together with people, and then turning it into reality together with the company. Since 2020 he has been doing exactly that at Committed Capital, with entrepreneurs and management teams who want to accelerate their growth.
Sijbrand is persistent, combining strategic insight with a good understanding of people, and he values personal contact. He lives in Amstelveen with his blended family of three children. He played football and hockey, but also loves the challenge of extreme triathlons.
As an entrepreneur, taking on an investor is like getting married, so the click has to be there. If you can trust each other, you can build on each other. And what I believe in every journey: make sure you surround yourself with good people.
