Join the largest community of more than 40,000 founders, advisers, and interns to help launch or grow your business.

Choosing your co-founder is arguably the most important business decision you'll make. Traditionally, entrepreneurs turn to friends and family when searching for business partners, but this search is often too limited in scope. Our free, online matchmaking service gives you access to the largest group of entrepreneurs ever assembled looking to join a startup or be joined on their venture, allowing you to cast a much wider net in your search for talent.

Strong team = strong foundation = better chance of success

Our team-building platform ensures you and founding team will:

- possess complementary skills
- have compatible personalities, goals, and values
- utilize proprietary tools to ensure your partnership lasts

Post a free profile today, search for and get discovered by other entrepreneurs, and find your perfect match.


On July 16, 2014 CoFoundersLab announced a merger with equity crowdfunding platform RockThePost to create a new company, Onevest. CoFoundersLab has been helping entrepreneurs build stronger founding teams faster since 2010. As our community grew steadily over the last few years, we realized that the next big hurdle our entrepreneur members were faced with was raising capital to launch and scale their new ventures.

Soon, you'll be able to build teams and raise capital in a single place called Onevest, but for now RockThePost and CoFoundersLab will remain separate websites under the umbrella brand Onevest. Eventually both the team-building platform and equity crowdfunding platform will happen on a single site called Onevest.

Please visit this ​​blog post to learn more about the merger and our plans for moving ahead to continue helping entrepreneurs succeed.

About RockThePost

RockThePost is our equity crowdfunding platform that connects high quality entrepreneurs with accredited investors interested to invest in exciting new startup companies.

RockThePost aims to be a resource for both entrepreneurs and investors by streamlining the capital raising lifecycle and allowing for a larger pool of accredited investors to seamlessly invest in featured companies on the platform.

Yes It Really Works

Simply put, this is why we do what we do. We measure ourselves by the number of successful companies that are born through our efforts of building a founding team. This is why we come to work each day and it is the ultimate measure of our success. We are extremely proud of the founding teams who met through CoFoundersLab. Some have graduated from well-respected accelerators while others are already hiring their first employees. If you found your co-founder though CoFoundersLab, please contact us and we'll do everything we can do get you some PR coverage.
