What C-Link does

C-Link, operating as Construction Link Limited, is a UK-based cloud SaaS platform founded in 2015 that digitises subcontract procurement for main contractors in the construction industry. It centralises supply-chain data, manages tender documentation and Invitations to Tender (ITTs), applies AI-driven bid analysis, integrates e-signatures, and tracks non-conformance reports (NCRs) to replace paper-based procurement workflows with a unified digital environment. The platform is modular, comprising Supply Chain Management, Tender Document and ITT Management, a Tender Document Builder, AI-Driven Tender Analysis, integrated DocuSign e-signatures, and Non-Conformance Reporting.

C-Link targets commercial directors, quantity surveyors, and digital transformation teams at main contractors, addressing pain points such as the statistic that over 90% of construction projects run over budget, 35% of Quantity Surveyor time is consumed by administration, and 54% of firms cannot find qualified QS talent. The platform is go-to-market is delivered through quote-based annual enterprise subscriptions sold via direct field sales with a 'Book a demo' motion, supplemented by self-serve access at app.c-link.com and an ROI calculator for mid-market prospects. The platform holds ISO 27001 and RICS certifications, integrates with DocuSign and CHAS, and counts Acorn, Coinford, Culena, Digital LL, Guildmore, O'Shea, Pye, Quinn London, and Structure Tone among its named customers.

Since the July 2025 cross-border merger with Australian firm E1 (EstimateOne), C-Link operates as part of the integrated E1 Group alongside the EstimateOne and Prosper platforms, giving it a dual UK-Australia footprint and access to a shared procurement ecosystem that has historically processed over £10bn in tendered project value. The business is private (no public listing), privately held (no disclosed external venture or private-equity funding), bootstrapped with a small 11-50 employee headcount, and based in London.
