Construction engineering platform SPEC Toolbox has raised $3 million in a pre-Series A

Shared 20 January, 2026

Construction engineering platform SPEC Toolbox has raised $3 million in a pre-Series A. The investment was co-led by Black Nova Venture Capital and Investible. The Melbourne design software platform rebranded after realising that design bottlenecks weren’t just a mass timber problem. They help designers overcome technical barriers to using other modern construction materials and automate complex engineering tasks.

SPEC Toolbox CEO Adam Jones said the pre-Series A validates their approach to solving the construction industry’s affordability and sustainability challenges. “With these funds, we’re accelerating our product roadmap, onboarding new suppliers in new product categories, deepening existing technical infrastructure and accelerating our mission to make innovation easy to specify for engineers,” he said.

Investible principle Ben Lindsay said, “We’ve been fortunate to watch Adam and Ringo over the past 12 months as they’ve first captured a clearly defined cross-laminated timber niche and are now thoughtfully expanding into the much larger manufactured products market.”
