CalcTree allows construction engineers to create and collaborate on calculations in a new and innovative way.

The SaaS startup has created a central repository that hosts and executes verified calculations. Unlike generic document storage systems, CalcTree helps automate the management and execution of calculation IP.

By removing low-value activities and adding integrations that take calculations from concepts to detailed designs and through to semi-automated procurement, CalcTree is empowering engineers to do their best work.

CalcTree, co-founded by Onur Ekinci, Mahan Lamei, and Tim Rawling, was recently built with and invested in by Antler, the global early-stage VC.

“Engineering calculations are notoriously manual, slow, and prone to human errors,” says Laura Faulconer, Associate Partner of Antler, “costing commercial construction projects up to 14% in rework, equating to millions of dollars for most projects.

“Having validated this problem with hundred engineers from small to top-tier firms like Arup, Jacobs, Aurecon, and Lendlease, the CalcTree team has developed a solution which addresses a set of related problems in one of the world’s biggest and most lagging sectors.”

“CalcTree provides a universal platform that allows engineers from all disciplines and jurisdictions across the globe to work faster and smarter, without throwing out the tools they know and trust,” says Ekinci. “Added with our marketplace of calculations created by experts and industry partners, CalcTree will quickly become the trusted source for the industry and a central hub for design.

“We are designing and building the platform in close collaboration with engineers across the value chain, making sure their unique complexities are elegantly and scalably addressed, and that effective calculation collaboration within and between these organisations can be established.

“Antler’s investment is going into the development of our private and public betas and supporting research.”
