What axes4 does
axes4 is a privately held software and services vendor founded in 2015, headquartered in the DACH region (firmographic city: Zürich; corporate office footprint: Vienna, Austria) and operating internationally. The company specializes in PDF accessibility — creating, verifying, and remediating documents that meet PDF/UA and WCAG standards — and sells a portfolio of Microsoft Office add-ins (axesWord, axesSlide), a desktop fixer (axesPDF), a REST API (axesPAC), an automation solution for high-volume conversion (axesFlip), and professional services (axesService, axesTraining). A free PDF Accessibility Checker (PAC) and a free web app (axesCheck) anchor a product-led growth funnel that funnels users into paid software and services.
The customer base skews heavily toward DACH public-sector and government organizations (Austrian Parliament, Land Berlin, Deutscher Wetterdienst, Swiss Confederation, TU Chemnitz, Hamburg, Schleswig-Holstein, Bavarian State Ministry, Austrian Federal Ministry, German Federal Employment Agency), with secondary penetration into large enterprises needing high-volume accessible PDF production. The 2025 release of PAC 2026 introduced AI-assisted semantic-structure verification (anomaly detection on headings, paragraphs, tables), and axesWord 25.9 beta added native PDF forms creation from Word.
Commercial mechanics mix one-time software licenses, recurring API/automation subscriptions, paid professional services and training courses (~450€ per course), and ticketed events (PDF Accessibility Summit at 59€/149€), with free tools driving awareness. Distribution combines direct website sales, contact-sales enterprise motions, a regional partner network, and an active event and community program (axes4 Day, PDF Accessibility Summit, Barcamp Digitale Barrierefreiheit). Demand is structurally reinforced by the European Accessibility Act and the German BFSG (enforced from 2025-06-28), and the company cites a CAAT study finding only 8.7% of ~70,000 sampled public-sector PDFs compliant, framing a large compliance gap as the market opportunity.
