GrabCAD story

Back in 2009, two young Estonian mechanical engineers noticed huge problems with their industry. No good library of CAD parts and assemblies existed, it was difficult to find talent, and it was a real pain to work with other engineers. Hardi Meybaum and Indrek Narusk started GrabCAD with the core belief that by embracing new internet-based technologies, they could radically transform a stagnant and old fashioned industry. They envisioned new forms of collaboration and openness to help mechanical engineers around the world save loads of time, stay super organized and have more fun.


Hardi and Indrek began building their dream. With only two mechanical engineers painstakingly coding a website in PHP, the first weeks of GrabCAD were slow. Suddenly, mechanical engineers from around the world noticed GrabCAD and started uploading their CAD models. In 2011, Hardi and Indrek decided to move headquarters from Tallinn, Estonia to Boston, USA to benefit from one of the hottest start-up scenes in the world. The GrabCAD Team had to grow to quickly build the tools and features Hardi and Indrek knew were needed to simplify and advance the multi-billion dollar field of mechanical engineering. GrabCAD is on track.

Ultimately, we are making the world a better place by crushing the status quo in mechanical engineering. To scale the online engineering community and build great tools for engineers all around the world, we are always looking for amazing people to join our team. If you are amazing and want to be part of something special, GrabCAD could be the place for you to learn and grow.
