What EstimateOne does
EstimateOne (E1), founded in 2008 and headquartered in Melbourne, operates Australia's largest construction tender marketplace, connecting over 900 head contractors with 50,000+ subcontractors and 7,000+ suppliers. In 2025 the platform hosted 24,049 tenders worth AUD $354 billion across commercial construction projects, with the company also maintaining operations in New Zealand, the United Kingdom, and Ireland. The platform centralizes the tender lifecycle—from project listing and document distribution through quote collection and analysis to subcontractor qualification—replacing the email-and-spreadsheet workflows historically dominant in Australian commercial building.
The E1 platform comprises a Tender Noticeboard for project posting, a Document Matrix for organizing project documents into trade-specific packages, an Addenda Wizard for issuing document updates with full audit trails, and a Living Address Book that maintains real-time subcontractor profiles with Australian Business Number (ABN) verification through integration with the Australian Business Register. In 2025, the company launched an AI-enabled Quote Analysis feature that uses natural language processing to ingest and standardize incoming subcontractor quotes, flag scope or price discrepancies via anomaly detection, and generate targeted clarification lists; this capability is included in the Builder Business and Enterprise tiers. A Project Chatbot enables subcontractors to query tender documents directly, while Speci-Finder provides keyword-based specification tracking and alerts for suppliers monitoring brand or material mentions in live tenders.
Revenue is generated primarily through three subscription tiers for head contractors—Builder Core at AUD $6,000/year, Builder Business at AUD $9,000/year (which includes AI Quote Analysis and E1 Network access to 40,000+ enriched subcontractor profiles), and Builder Enterprise at custom pricing with SSO, team-based permissions, and dedicated account management. Subcontractors and suppliers access the platform through free tiers with limited functionality, with paid upgrades unlocking AI-powered project qualification, advanced specification search, and expanded tender access. Distribution combines a self-serve web platform for the long tail of subcontractors and suppliers with a sales-led enterprise motion for larger builders. Co-founded by Andrew Ritchie and Michael Ashcroft—both commercial estimators—the company raised AUD $24.6 million from Potentia Capital and Saniel Ventures in January 2022 and acquired Netherlands-headquartered 12Build in January 2026 to support international expansion.

EstimateOne competitors and assessment
Company assessmentDirect peers
- BuildingConnected (Autodesk): Direct US-based construction tendering marketplace that connects general contractors with subcontractors for bid management. Acquired by Autodesk in 2018 and integrated into Autodesk Construction Cloud, it is the closest global functional competitor to E1's marketplace, differing mainly in geographic focus (US vs. ANZ/UK).
- Buildxact: Australian-headquartered estimating and job management SaaS targeting small-to-medium residential builders. Directly comparable to E1 in geography (ANZ) and overlapping customer base of builders, though more focused on residential takeoffs/estimating versus commercial tendering marketplaces.
- iTWO (RIB Software): Enterprise construction estimating and tendering software (now part of Schneider Electric) used by large contractors globally for 5D BIM-based cost estimation. Comparable to E1 in the preconstruction/estimating workflow but skews toward enterprise design-build contractors rather than the marketplace model.
- PlanRadar: European-headquartered SaaS for construction documentation, defect management, and tendering tasks. Comparable as a vertical SaaS serving subcontractors and general contractors across construction workflow stages, with strong international presence similar to E1's UK/Ireland ambitions.
Broad incumbents
- Procore: Leading global construction management platform covering preconstruction, project management, and financials. While much broader than E1, Procore's preconstruction/tendering modules overlap with E1's core offering and represent the most credible bundled competitive threat, especially as Procore expands internationally.
- Aconex (Oracle Aconex): Construction collaboration and project document management platform (acquired by Oracle). Overlaps with E1's document control, addenda distribution, and tender collaboration functionality, especially for large infrastructure and commercial projects where both compete.
- Autodesk Construction Cloud: Broad construction technology suite from Autodesk encompassing BIM, project management, and tendering (via BuildingConnected). Represents the principal bundled competitive threat to standalone tendering platforms like E1, particularly as Autodesk pushes integrated preconstruction workflows.
Emerging players
- LetsBuild (now Procore): Construction project management and progress tracking SaaS acquired by Procore in 2022. Comparable as a workflow tool for general contractors managing on-site execution and reporting, adjacent to E1's preconstruction focus but increasingly bundled into Procore's offering.
Regional players
- Assignar: Australian-headquartered construction workforce and asset management SaaS for subcontractors and contractors. Comparable as an ANZ-headquartered vertical SaaS serving the construction subcontractor ecosystem, though focused on crew/asset scheduling rather than tendering.
- Mastt: Australian-headquartered project management and reporting SaaS for capital projects and construction programs. Comparable as an ANZ-based vertical construction SaaS, though focused upstream on portfolio/program management versus E1's tender marketplace.
