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
Problem
40% of an engineers’ time is spent searching through past projects, rebuilding calculations and wrangling data
Solution
CalcTree no/low code platform takes away a lot of the manual steps, freeing up engineers to create more innovative and sustainable designs

Our founders

Having first-hand experience with engineering workflow inefficiencies, we built CalcTree to create a step-change for how engineers design and collaborate.
Mahan Lamei
CTO
Frustrated with the inefficiencies of re-creating calculations and workflow logic on most GeoTechnical projects, Mahan believed there had to be a better way.
Onur Ekinci
CEO
Onur saw first-hand the data fragmentation challenges in the construction industry during his time as a Product Manager at Archistar.
Tim Rawling
COO
Tim lived the pain of calculation management at Arup as a senior structural engineer and knew it had to be addressed differently.

What industry leaders are saying

“In the midst of a tech revolution in the construction industry, CalcTree is providing a platform for automated engineering calculations that has been done manually since the beginning of time. Not only that, but solving it in a way that enables cross-functional collaboration is truly necessary and revolutionary.”
Sean McCreanor
CEO, Assignar
“Collaboration during the construction process is still very inefficient, exacerbated by a lack of tools that address the unique needs of industry stakeholders. CalcTree’s product is transforming collaboration and efficiency of engineering teams globally”
Diana Swenton
VP, Venture Capital
"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.”
Guillaume Bazouin
Head of Startup Programs
“CalcTree's platform revolutionizes the workflows of engineering calculations, enabling real-time collaboration between cross-functional teams and democratizing knowledge access for AEC professionals across the globe. We are grateful to CalcTree and the team for choosing us as their partner on their journey.”
Shub Bhattacharya
General Partner
