Melbourne-based startup CLT Toolbox has raised $1 million in a bridge funding round to expand its mass timber design software, less than 12 months after it raised an initial $1.5 million seed round in October 2023.

The fresh cash injection includes contributions from climate-focused VC firm Giant Leap as well as Archangel Ventures, Adrian Hondros, Ecotone Ventures and angel investor Harrison Rose.

CLT Toolbox offers a design software platform specifically tailored for mass timber construction. The platform provides structural engineers with tools to design complex timber structures.

The platform also includes robust supply chain functionalities, enabling users to source materials and components efficiently and sustainably.

The funding will be used primarily to support CLT Toolbox’s expansion into the European and US markets and bolster the company’s efforts to make mass timber a mainstream material in construction projects worldwide.
