Foundamental VC leads investment in CalcTree

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.
