SPEC Toolbox is a Melbourne-based construction engineering platform founded in 2023 by structural engineers Adam Jones and Ringo Thomas. Originally launched as CLT Toolbox to serve the cross-laminated timber niche, the company rebranded after discovering similar design bottlenecks across a wider range of modern manufactured materials. Its cloud software automates complex engineering calculations, helping designers more easily specify affordable and sustainable materials in building projects. The product has attracted more than 6,000 user sign-ups and 35 product suppliers and has already expanded its footprint into Europe, the UK, and North America. CEO Adam Jones says the new capital will accelerate the product roadmap, onboard additional suppliers, and deepen technical infrastructure. To date, SPEC has raised multiple rounds, including a $1.5 million Seed round in October 2023 and a $1 million bridge round in 2024, prior to the current pre-Series A fundraise.
