Helping you build and share your creations

We’re creating a calculation management platform to bring engineering teams, design and data together

Get started

Traditional engineers play a vital role in society

They build the infrastructure we depend on a daily basis, from roads, cars, to hospitals, schools and our homes

“In the construction industry, knowledge is slowly built over the course of many years. In a field where every new project is effectively a prototype, nothing beats experience in order to find an elegant solution. CalcTree makes this knowledge easy to find, use and share. The potential in productivity and safety gains is enormous.”
