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

At W4 Games, we are honored with OSS Capital being our lead investor. Working with JJ and being able to share his insights about the COSS world has been an incredible experience, and he is one of the few individuals who truly understands the delicate relationship between commercial entities and FOSS communities.
