What Fonn does

Fonn (marketed as Access Fonn) is a mobile-first construction site management software product developed and sold by The Access Group, a UK-based private software conglomerate. The platform is built for site workers rather than office staff, offering native iOS and Android apps plus a desktop command centre, all backed by cloud-hosted infrastructure and an open public API. Core capabilities include document and drawing management with automatic version control, snagging and defect tracking with geo-tagged photo evidence, digital forms aligned to UK Building Safety Act Golden Thread and Part L compliance, a Scope of Works / Work Breakdown Structure module linking phases, drawings, forms, tasks, timesheets and documents, RFI and submittal workflows, geo-fenced timesheets, one-click daily reports, and cross-project portfolio dashboards.

Fonn is tightly integrated with two sister products within The Access Group's Access Construction ecosystem: Access Coins Evo (construction ERP) and Access ConQuest (estimating). Projects created in Coins Evo flow automatically into Fonn with bidirectional data sync, eliminating manual duplication and positioning Fonn as the field-execution layer of an end-to-end construction back-office stack. Customers named in case studies span tier-1 homebuilders through specialist subcontractors, including Excel Group, Natta, Ascia Construction, Peter Ward Homes, Lanyon Development and Barratt Developments, with broader distribution across The Access Group's 1,000+ UK construction customer base.

The product is monetised via a flat annual subscription covering unlimited users and unlimited projects, with all subcontractors and trade workers included at no extra cost; additional modules are sold as add-ons. Go-to-market combines enterprise field sales through The Access Group's direct organisation, digital self-serve onboarding (app.fonn.io), and cross-sell from Coins Evo and ConQuest. Operating geography is primarily the UK and Ireland, with no disclosed expansion beyond. The platform holds ISO 27001 certification and is independently ranked in the top 1% for cybersecurity by BitSight, and has won multiple Construction Computing Awards in 2025.

Direct peers

• Bluebeam (Nemetschek Group): PDF-based markup, collaboration, and drawing management platform widely used in construction. Competes with Fonn's drawing version control and markup/annotation capabilities, with deep penetration among UK/AU and US contractors.
• Newforma: Project information management platform for AEC firms, focused on email/document management, RFIs, submittals, and project collaboration. Comparable to Fonn's document control, RFI, and audit-trail functionality, particularly for mid-market architects and contractors.
• LetsBuild: Construction site management and quality/safety platform with strong European presence, offering site diary, snagging, drawings, and progress tracking. Directly comparable to Fonn's mobile site-management scope with similar mid-market European contractor customer profile.
• CoConstruct: Construction project management software for custom home builders and remodelers, offering scheduling, budgeting, client communication, and document control. Comparable to Fonn's homebuilder segment targeting with strong residential workflow depth.
• PlanGrid (Autodesk Construction Cloud): Mobile construction drawing and document management platform, now part of Autodesk Construction Cloud. Directly overlaps with Fonn's document/version control and snagging features and competes for the same site-manager buyer persona.
• Buildertrend: End-to-end construction project management SaaS for residential builders and remodelers, including scheduling, job costing, customer portal, and drawings. Comparable to Fonn in addressing frontline construction workflows, with stronger US focus and consumer-facing portal capabilities.
• Fieldwire: Mobile-first construction field-management platform for task management, punch lists, drawings, and inspections. Highly comparable to Fonn's mobile-first positioning for site workers, with similar feature scope (snagging, drawing version control, forms) and overlapping customer base among trade and specialty contractors.
• Procore: Leading cloud-based construction project management platform serving general contractors, owners, and specialty contractors globally. Closest direct competitor to Fonn's site-management, document control, and RFI/submittal functionality, with significantly larger scale but broader, less mobile-first UX.
• RIB Software (iTWO): Enterprise construction ERP and project management platform (iTWO) used by large contractors globally. Comparable to Fonn's project-management and WBS functionality but oriented toward enterprise/ERP scope rather than mobile site workflows.

Broad incumbents

• Autodesk Construction Cloud: Autodesk's integrated construction portfolio (including PlanGrid, BIM 360, Assemble) covering design through construction. Overlaps broadly with Fonn but operates as a much larger, multi-product suite rather than a specialist mobile site-management tool.
