All software should be open and more people can become entrepreneurs


A New Approach to Venture

Founded by Sid Sijbrandij, Open Core Ventures (OCV) is a venture capital firm that starts commercial open source software companies. Our team identifies open source software projects with traction, recruits passionate project founders and contributors, and launches new companies. OCV companies aim to create tangible value for the open source community by providing access to resources and reducing the barrier to entrepreneurship.

OCV believes in the power of open core, and the impact of open learning and collaboration. Our approach diverges from conventional venture capital because OCV starts companies and recruits founders; OCV does not invest in existing companies. The OCV model enables experienced, capable, and technical founders who otherwise would not have the resources to launch a successful startup.

OCV does not make investments in existing open core companies.

OCV is not currently accepting new limited partners.



"If you're going to pour your heart into your open source project, you might as well build a world-changing business at the same time."

Mike McNeil
CEO at Fleet

"Connecting with a CEO and seed funding meant we had great momentum building the Open Core model from day one. With OCV, building a growth business around open source is low-risk and high-reward."

Zach Wasserman
CTO at Fleet

"After a two-decade long career at a leading global tech giant, OCV inspired me to take the entrepreneurial leap to found FlowFuse."

Nick O'Leary
CTO at FlowFuse
