Engineering calculation management software designed to replace manual time-consuming and error-prone methods
Foundamental, a Berlin-based VC firm with a focus on AEC technology investments, has led a €2.3 million pre-seed round in engineering calculation platform CalcTree.
CalcTree helps engineers turn complex calculations into trusted, reusable templates and workflows — reducing the risk of costly errors on large-scale engineering projects, where manual, time-consuming methods often lead to mistakes and expensive rework.
The software helps teams consolidate tooling and data, which is traditionally scattered across niche software packages, Excel, code, PDFs and handwritten documents.
“Investing in CalcTree is part of our strategy to nurture the development of a modern tech stack for the industry,” said Shubhankar Bhattacharya, General Partner at Foundamental. “We’re excited about the strategic overlap amongst our portfolio and the compounding benefits for end users through integrations amongst them.
“Online collaboration tools are now a necessity, yet engineering workflows are being held back by antiquated systems that create inefficiencies and rework. CalcTree’s platform revolutionizes the workflows of engineering calculations, enabling collaboration between cross-functional teams and democratizing access to knowledge for AEC professionals across the globe.”
CalcTree is described as “Github meets Notion” for the engineering sector and is the brainchild of co-founders Onur Ekinci, Tim Rawling and Mahan Lamei, ex-Archistar, Arup and Plaxis (pictured above). The company has signups from 35 European countries and engineers from top-tier firms like Arup, Jacobs, Aurecon, and WSP.
CalcTree will join Foundamental’s broad portfolio of investments, which includes Speckle, Snaptrude and Rayon.
Other investors in CalcTree include Australia’s peak non-government, not-for-profit standards organisation Kungari, a subsidiary of Standards Australia, Boston-based fund Suffolk Technologies, Antler VC, Autodesk & Bentley employees.
