Talking to JJ about open source is like drinking from a fire hose. He is a fast moving, intelligent, empathetic investor who wants the entire open source industry to win. A true evangelist. The OSS Capital team is a must-have on the capable for any COSS company

Peer Richelsen, Cal.com

JJ has been a great mentor, a genuinely committed partner to our team, and a good friend. He understands early-stage COSS companies and gets personally involved by providing direct support in navigating through the critical early challenges. The team at OSS Capital were particularly helpful to me in opening doors: they have a strong network and understood the value proposition we had to offer to potential customers.

Liyas Thomas, Hoppscotch

OSS is committed to the values of open source software which aligns strongly with the transparency and community development of blockchain - we immediately understood one another and we are honoured to call them our partner on this journey to build the Parallel world and game.
