Grai is a venture building studio.

We partner with entrepreneurs and corporations to validate, build, and scale new products and businesses.

In the last 15 years, 52% of the Fortune 500 companies have disappeared. Despite having access to large resources, corporations are not immune to this speed of change.

New startups are taking market share at dazzling speed, and giving large companies a hard time keeping up. However, way too often founders run out of resources and struggle to scale their business.

At Grai, we combine the best of both worlds. We leverage the abilities of entrepreneurs and the vast resources of corporations to develop new business, with a focus on execution speed and future growth in overlooked markets and offerings.

European roots, global thinking.

Our core team is based in Cluj-Napoca, Romania, Eastern Europe's leading IT&C hub, and we’re proud to say our clients come to us from all around the world.

We pair our deep market knowledge with a global perspective offered by our extended team and advisors — our international network of designers, strategists, directors, and developers who collaborate to execute projects and provide a valuable global perspective on our work.
