Value proposition

Removes the technical and economic barriers to sustainable construction by automating complex engineering calculations, reducing design time from weeks to minutes and making low-carbon materials as easy to specify as traditional concrete and steel.

Products and solutions

Mass Timber Design Suite (CLT, Glulam, and LVL design automation), Green Steel Specification Module, Low-Carbon Concrete Design Tool, Embodied Carbon Calculator & Reporting Engine, Automated Structural Design Guide Integration

Unique value

The platform is the first to bridge the gap between complex structural engineering codes and sustainable material procurement, transitioning from a niche timber tool to a comprehensive multi-material 'specification' ecosystem.

Target customer

Structural engineers, design consultants, architects, and property developers looking to reduce embodied carbon in construction projects.

Industries served

Construction Technology (ConTech), Structural Engineering, ClimateTech / Decarbonization, Real Estate Development

Technology advantage

Proprietary automation of international structural design codes (including Eurocode and Australian Standards) combined with real-time carbon data, allowing engineers without specialized 'green' expertise to safely and efficiently design low-carbon buildings.

How they differentiate

Unlike general structural analysis software or standalone carbon calculators, SPEC Toolbox (formerly CLT Toolbox) integrates structural design automation with real-time carbon accounting and supplier-specific material specification, specifically optimized for low-carbon materials like mass timber and green steel.

Main competitors

Dlubal Software (RFEM), One Click LCA, Calculatis by Stora Enso

Key partnerships

BlueScopeX (Venture arm of BlueScope Steel), WoodSolutions (Industry research and advisory partner), Black Nova and Investible (Lead investment partners), Various sustainable material suppliers for integrated specification data

Notable customers

WSP, AECOM, Lendlease, Stora Enso (Partner), BlueScope Steel (Partner)

Major milestones

Launched CLT Toolbox in 2022 to automate mass timber design., Raised $1.5M Seed round in October 2023 to enter the UK market., Rebranded to SPEC Toolbox in January 2025 to encompass green steel and low-carbon concrete., Secured $3M Pre-Series A in January 2025 to accelerate global decarbonization efforts.

Growth metrics

Expanded from a timber-only tool to a multi-material platform; team growth to 11-50 employees; successful expansion into the UK and European markets within two years of founding.

Market positioning

Specialized ConTech/ClimateTech SaaS targeting the 'specification gap' in sustainable construction.

Geographic focus

Australia (HQ), United Kingdom, Europe, and North America.

Patents and IP

Proprietary structural design algorithms and carbon calculation engines; no public patent filings disclosed as of early 2025.
