What Fax.Plus does
Fax.Plus is a cloud-based online faxing service that enables individuals, SMBs, and enterprises to send and receive faxes without traditional fax machines or phone lines. The platform is delivered through a web application, desktop apps (Windows/macOS), and native iOS/Android mobile apps, and supports email-to-fax workflows, fax broadcasting, and programmable integration via a RESTful Fax API. The company is operated by Alohi, a Swiss technology company headquartered in Plan-les-Ouates that maintains a broader productivity suite including Sign.Plus (e-signatures), Scan.Plus (mobile scanning), and Dial.Plus (AI-powered phone). Fax.Plus serves over 5 million customers globally, with named enterprise users spanning the United Nations, PwC, IBM, Airbus, Roche, 3M, FIFA, Cloudflare, and Harvard University across verticals such as healthcare, legal, financial services, real estate, education, and IT. The service carries a strong compliance posture—SOC 2 Type II, HIPAA, ISO 27001, GDPR, and CCPA—with Swiss-hosted infrastructure and data residency options in over 20 regions.
Fax.Plus monetizes primarily through tiered monthly subscriptions (Basic $6.99, Premium $13.99, Business $27.99, Enterprise $79.99) augmented by usage-based per-page credits at $0.20/page and custom multi-year enterprise contracts. The go-to-market combines a product-led growth self-serve funnel (free sign-up, mobile/desktop app stores, Google Workspace Marketplace listing) with direct enterprise sales via "Schedule Demo" CTAs for larger accounts. Additional distribution comes from native integrations with Microsoft, Slack, and Zapier, plus a developer-facing Fax API for white-label and embedded use cases. Strategic differentiators include comprehensive regulatory compliance certifications, a 256-bit AES encryption architecture, AI-powered text and data extraction from incoming faxes ("Fax AI"), and a unique email-to-fax workflow that simplifies adoption for non-technical users.
The platform's underlying technology stack supports fax number availability in 48+ countries with outbound sending to 180+ countries, positioning Fax.Plus as a global infrastructure play in the online fax market. According to a third-party market estimate, the Online Fax Market is valued at $11.46 billion in 2025 and projected to reach $28.44 billion by 2033, growing at a 12.03% CAGR. The company has received support from Innosuisse, the Swiss Innovation Agency, indicating institutional endorsement but no external venture funding rounds are disclosed in the available materials.
