Support should be open to all.
Anyone can build anything now. Founders shouldn't need a warm introduction to find the people who can help them. So we make that support visible, and give the people who offer it a room of their own.

Erdinc Ekinci
Founder of Co-Capital and Openfor.co
“The best support in venture shouldn't depend on who you already know. We're making it visible, and bringing the people behind it together.”

What people ask us.
Is membership really free?
Yes. Co-Capital's community has no fees and no business model. It exists to build relationships between the people who back founders.
Who can join the private community?
Venture capitalists and angel investors first, then ecosystem builders, and senior operators and mentors with real experience to share. About nine in ten people featured with us are investors.
Do you make introductions to founders?
No. Founders build visible work through Openfor.co, and members can weigh in where they choose. Relationships form on their own.
What's the Atlas, and can I contribute?
The Open Ecosystem Atlas maps 1,890 venture supporters across 11 countries and is free for everyone to use. Anyone can spot, report and verify an entry, and every contribution is credited.
What does an episode involve?
A one-on-one podcast or webinar, prepared with you around your experience and how you think. We cut it to short-form and carry it to founder and investor audiences.
Is anything here an investment offer?
No. Membership carries no investment rights, and nothing on this site is an offer of securities or investment advice.
Can I invest through Co-Capital here?
No. This site and the community are not a way to invest, and nothing here asks for or accepts capital. Membership is about relationships, content and contribution.
How is Co-Capital related to Openfor.co?
Openfor.co is the founder-facing side of the same ecosystem. Co-Capital is the side for investors and venture supporters.
