About Us

The various uses of Cannabis for medicinal and industrial purposes are already a widely debated topic and seen in practice in developed countries. In Brazil, we still have a long way to go.
Above economic interests, we have important causes to fight linked to cannabis, from the health of thousands of people, sustainability and even

job creation. Much more than generating business, expanding entrepreneurial culture and cultivating innovation, we need to accelerate opportunities in a developing ecosystem.

The Green Hub group has been working to connect players interested in initiatives related to acceleration and investment in the cannabis sector, both medicinal and industrial, and we feel that the time has come to increasingly share ideas, values and goals.

We start the ecosystem convergence phase and The Green Hub positions itself as a focal point and connector in this scenario.

The finish line is the same for everyone and we need to join forces and cross-reference experiences.

Who we are

We are a specialized network of innovation and technology entirely focused on the cannabis industry. We know that connections and partnerships are essential for us to achieve a single goal: to benefit the world on several fronts with a single plant. We want to attract talented people and companies engaged in the different spheres of the global cannabis ecosystem. Our goal is to be the leading HUB of research, education and connection between innovative entrepreneurs, investors, the corporate, academic and government sectors.
