What Clearbox does

Clearbox operates Transportal, a cloud-based Common Data Environment (CDE) platform built for the construction industry and delivered through Kier Transportal Ltd, a UK private limited company that is a subsidiary of Kier Group. Founded in 2013 and headquartered in Basingstoke with an operating address in Salford, the company employs 11-50 people. Its platform addresses fragmented communication and document handling between office and site teams across construction and infrastructure projects, serving as a single source of truth for project information, document control, communication, and asset data.

The platform comprises four integrated modules operating on shared cloud infrastructure: a Document Management System (DMS) for real-time document viewing and data enhancement; Forms for digital data collection in the office or on site; Comms for 24/7 cloud-based team collaboration; and Assets for project asset data with secure, authorized access. A full audit history tracks who has done what and when across all modules, supporting compliance and accountability. The product emphasizes real-time collaboration, elimination of duplication, digital dress rehearsals to reduce on-site risk, and stored data supporting accurate cost and time prediction. No public API, SDK, or AI/ML capabilities are disclosed.

Clearbox's commercial model is not publicly disclosed: pricing is not published, products are sold through direct B2B channels to construction companies via website inquiry and downloadable brochure, and customer composition, revenue, and geographic markets are not reported. The company underwent a legal entity and name change in 2024, rebranding from Kier Transportal to Transportal, which suggests an active repositioning of the product identity relative to its Kier Group parent. As a non-venture-backed subsidiary, the company does not appear on funding databases and operates with the structural backing of Kier Group rather than external capital.
