What HelloFax does
HelloFax, founded in 2010 in San Francisco and now operating as Dropbox Fax, is a cloud-based document transmission service that enables users to send and receive faxes electronically without physical fax machines. The core product converts documents to PDF for web-based or email-based delivery, integrates natively with Dropbox, Google Drive, Box, OneDrive, and Evernote, and supports fax number porting (US and Canada) along with international faxing to 70+ countries. The platform is API-accessible and packaged within the broader Dropbox Sign product family following Dropbox's acquisition of the company.
The technology stack centers on a SaaS fax engine with email-to-fax ingestion, encrypted transmission, and cloud-storage interoperability, backed by SOC 2 Type 2, HIPAA, and ISO 27001 certifications. Distribution is purely digital and product-led: users self-register at app.hellofax.com, start on a 5-page free tier with no credit card required, and upgrade to monthly subscription plans or pay-as-you-go ($0.99 per fax up to 10 pages, $0.05/page overage). The company does not disclose revenue, headcount, or independent funding; it operates as a wholly-owned subsidiary of Dropbox (NASDAQ: DBX) with a firmographic headcount of 11-50 employees.
Customer segmentation is horizontal, spanning individual consumers, SMBs, mid-market and enterprise users, with explicit use-case focus on healthcare (HIPAA-compliant patient documents), legal professionals (contracts and court filings), and general business document transmission (NDAs, sales contracts, leases, tax forms). Marketing is conducted through Dropbox-owned digital channels, customer testimonials, and third-party validation (Wirecutter's Best Online Fax Service for multiple consecutive years). Strategic product surface extends to developer APIs/SDKs, a Salesforce integration via Dropbox Sign, and exposure to the parent's AI-powered Dropbox Dash ecosystem.
