Faxio

Overview

Faxio modernizes faxing by turning any smartphone into a fax machine. Users can scan documents with their camera, import files, and send faxes to over 50 countries—all without a physical fax machine.

The Problem

Despite the digital age, many industries still require faxes for legal and compliance reasons. Traditional fax machines are expensive, inconvenient, and increasingly impractical for mobile workforces.

Constraints

• Integration with global telecom networks for fax delivery
• Document quality requirements for legal/medical documents
• Regulatory compliance for data handling
• Competitive pricing against established fax services

Our Role

Full product development including:

• Mobile app development for iOS and Android
• Backend infrastructure for fax transmission
• Integration with Twilio for global fax delivery
• Payment processing and subscription management

Key Decisions

Twilio for fax infrastructure: Provided reliable global coverage without building our own telecom infrastructure.

Camera-based scanning: Eliminated the need for separate scanner apps, improving user experience.

Pay-per-use pricing: More attractive to occasional users than subscription-only models.

Implementation

• Real-time document edge detection and perspective correction
• Cloud-based document processing and format conversion
• Global fax number support with coverage verification
• Delivery confirmation and retry logic

Results

• Thousands of active users across 50+ countries
• High delivery success rate (99%+)
• Strong retention among business users
• Positive reviews highlighting ease of use

What We’d Do Differently

Earlier implementation of receipt/confirmation faxing would have addressed a common enterprise requirement sooner.
