Construction technology platform SPEC Toolbox, fresh from a rebranding to reflect the broadening scope of its business in automating complex engineering tasks, has raised $3 million in a Pre-Series A funding round.
The capital raise was led by Black Nova and Investible with the funds destined to fast-track global adoption of the SPEC Toolbox platform which bridges the technical gap between product suppliers and designers.
Founded in 2022 as CLT Toolbox, initially as structural design software to simplify mass timber calculations for building engineers, the rebranding to SPEC Toolbox follows the startup’s findings that design bottlenecks are stifling the adoption of all innovative building products globally.
The company says that by removing the technical barriers that often prevent designers from selecting modern materials, SPEC Toolbox has created a streamlined pathway for product suppliers to get specified.
“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,” says Adam Jones, founder and CEO of SPEC Toolbox.
“The strong backing from leading VCs validates SPEC Toolbox's approach to solving the construction industry's affordability and sustainability challenges.”
Jones, a structural engineer, works closely alongside founding team members Ringo Thomas, the company's chief commercial officer, Lelissie Bedada and Ikhsan Agustian.
While the platform originally focused on cross-laminated timber, it has since expanded to include eight product categories that Jones says allows engineers find more solutions for projects that “challenge the norm”.
“SPEC Toolbox was born of real-world frustration with how products get specified, which in turn was inhibiting adoption of modern and sustainable construction materials,” says Matt Browne, managing partner at Black Nova Venture Capital.
“The team has turned those insights into a platform that makes complex products easier to specify, at scale.”
Prior to the latest round, SPEC Toolbox raised about $2.5 million including a $1.5 million seed round at the end of 2023 that was led by Archangel Ventures with participation from BlueScopeX, Gravel Road Ventures and Flying Fox Ventures.
Black Nova and Investible joined the share register in 2024 through a $1 million bridge funding round.
“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,” says Ben Lindsay, investment principal at Investible.
“Early customer response has been encouraging, and we were excited to co-lead this round alongside Black Nova in support of what the team is building.”
The startup says its platform has found “clear product-market fit” by effectively connecting innovative suppliers with a global network of designers.
Since the seed round, SPEC Toolbox has expanded into Europe, the UK and North America, while securing more than 6,000 user signups and listing over 35 product suppliers.
“This momentum validates the platform as a vital link for the construction industry, driving adoption across all major regions globally,” says SPEC Toolbox.
When announcing the rebranding to SPEC Toolbox in September, Jones said the company’s goal is “to be the best software in any product category we enter, empowering the industry to innovate and build a more sustainable future”.
