What InterFAX does
InterFAX is a cloud-based enterprise fax service founded in 1996 and now operated as a product brand within Upland Software, Inc.'s (NASDAQ: UPLD) Content Lifecycle Automation portfolio. The platform enables organizations to send, receive, and route faxes programmatically via a web interface, email integration, or developer API, replacing legacy fax hardware and telephone lines with cloud-native infrastructure hosted on AWS across the United States, Canada, and Europe. Its flagship product is complemented by InterFAX+AI, launched in 2026, which adds AI-enabled document capture, image processing, and intelligent routing into digital workflows. Reported operational metrics include 99.95% uptime, 24/7/365 global support in 58 countries, and a 98.5% customer satisfaction rate.
The platform serves primarily healthcare organizations — including hospitals, oncology practices, transplant coordination networks, and behavioral health providers — alongside education, financial services, manufacturing, nonprofit, hospitality, and engineering customers. Key integrations include Epic electronic health records, Salesforce CRM, and OncoEMR, while compliance certifications span HIPAA, PHIPA, PCI DSS, and SOC 2 Type II. Notable reference customers include TxMultilisting (organ transplant network), OncoEMR, a Top 50 US Hospital, and a university law school clinic.
InterFAX monetizes through subscription-based cloud fax services with usage-based components, distributed via a hybrid go-to-market combining direct enterprise field sales, self-serve product-led growth through a 30-day free trial with free credits, and a partner/reseller program. The company targets technical buyers through a developer API and Developer Center while also serving SMBs via self-onboarding. Leadership includes SVP & GM Shawn Freligh and CEO/CTO Yehuda Alon; the company is privately held as a product line within publicly traded Upland Software, headquartered operationally in Austin, Texas.
