TeleMessage

TeleMessage is an Israeli enterprise communications software company headquartered in Petah Tikva. Founded in 1999 by Guy Levit and Gil Shapira, the company developed products for mobile messaging, carrier services, enterprise communications, and the regulated capture and retention of communications content. Its offerings have included SMS and MMS services, SMS-to-landline conversion, mobile email and PC-to-mobile messaging, secure enterprise messaging, high-volume multichannel messaging, and archiving of texts, voice calls, and selected messaging-platform content. The company began in Israel and raised more than US$10 million during its first two investment rounds. Its early business was closely connected to mobile-network operators and messaging infrastructure. In 2004, Rogers Wireless selected TeleMessage's SMS-to-Landline technology for its TXT 2 Landline service. Verizon Wireless subsequently introduced a related service in the United States in 2006, allowing typed text messages to be converted into audio and delivered to landline recipients. TeleMessage also supplied messaging-related services to operators and enterprise partners including Sprint Nextel and Rogers Communications. In August 2005, TeleMessage was acquired by Messaging International plc. The acquiring company later traded on the London Stock Exchange's AIM market under the Messaging International name. TeleMessage continued to develop carrier and enterprise messaging products, including PC-to-mobile communications and messaging tools aimed at professional users. In 2013, Sprint began selling a TeleMessage service that enabled doctors and clinicians to send messages designed to meet HIPAA-related requirements. The company later shifted greater emphasis toward communications governance, compliance, and electronic discovery. Its Mobile Archiver product was designed to capture and preserve mobile communications from corporate and bring-your-own-device environments, including SMS, MMS, voice calls, WhatsApp, and WeChat content. Its Secure Enterprise Messaging offering provided mobile applications and APIs for internal business communications, while its Mass Messaging products supported bulk distribution through SMS, MMS, voice, fax, email, and mobile applications. TeleMessage was delisted from the British stock market and privatized in 2017. It subsequently joined the United Kingdom G-Cloud public procurement framework and participated in a financial-compliance partner program managed by Verint Systems. In 2019, it joined NICE Actimize's X-Sight Marketplace. In February 2020, Proofpoint partnered with TeleMessage to use its Mobile Archiver technology for capturing text, voice, and WhatsApp communications. The company also worked with Microsoft on the governance and protection of data arriving from Microsoft 365 services. On February 20, 2024, TeleMessage was acquired by Smarsh, a provider of communications capture and archiving technologies. The transaction placed TeleMessage within a larger compliance and information-governance portfolio, alongside products serving financial services, government, and other regulated organizations. TeleMessage received renewed public attention in May 2025 after reports that a modified version of Signal, branded TM SGNL and developed for message archiving, had been used by Mike Waltz, then a former U.S. national security advisor, and other government-related users. Reporting also connected the service to a federal contract for mobile electronic-message archiving that began in February 2023. During the same period, TeleMessage suspended worldwide services after a significant cybersecurity incident. Attackers claimed to have accessed internal systems and exposed archived conversations. Subsequent reporting raised concerns that communications handled by the modified Signal application were not protected by end-to-end encryption during transmission to archival systems or while stored. These events made TeleMessage a prominent…

TeleMessage was founded in 1999 in Israel by Guy Levit and Gil Shapira. The company initially concentrated on mobile messaging and communications infrastructure, raising more than US$10 million in its first two investment rounds. Its early products addressed both consumer-facing carrier services and the conversion of mobile messages into forms usable by fixed-line telephone recipients. A significant early commercial relationship came in 2004, when Rogers Wireless selected TeleMessage's SMS-to-Landline technology for its TXT 2 Landline service. The platform used speech technology to convert text messages into audio for delivery over a landline. Verizon Wireless introduced a similar TeleMessage-powered service in June 2006. Rogers Communications and Sprint Nextel were among other operators associated with TeleMessage messaging or mail-plugin offerings. In August 2005, Messaging International plc acquired TeleMessage. Messaging International subsequently became publicly traded on the London Stock Exchange's AIM market under its own name. TeleMessage remained associated with mobile messaging and enterprise communications products during this period. In 2013, Sprint began marketing TeleMessage's PC-to-mobile offering to doctors and clinicians for messaging intended to satisfy healthcare privacy requirements. The company later broadened its focus from message delivery toward communications control and compliance. Its Mobile Archiver product was designed to capture mobile texts, multimedia messages, voice calls, and selected third-party messaging content for regulatory retention and electronic-discovery purposes. The platform addressed both company-issued phones and bring-your-own-device environments. TeleMessage also offered Secure Enterprise Messaging, which combined mobile applications with APIs for integration into business systems, and Mass Messaging for multichannel distribution through SMS, MMS, voice, fax, email, and mobile applications. TeleMessage was removed from the British market and privatized in 2017. It subsequently became part of the United Kingdom's G-Cloud procurement framework and joined a financial-compliance partner program operated by Verint Systems. In 2019, TeleMessage joined the NICE Actimize X-Sight Marketplace. Proofpoint partnered with the company in February 2020 to capture text, voice, and WhatsApp communications through Mobile Archiver. TeleMessage also worked with Microsoft on the protection and governance of data originating in Microsoft 365 services. The company received a 2020 Finovate Award for Best Regtech Solution. On February 20, 2024, Smarsh acquired TeleMessage. The acquisition aligned TeleMessage's mobile-message capture capabilities with Smarsh's broader communications compliance and archiving business. TeleMessage became the subject of intense scrutiny in May 2025. A modified Signal-based application known as TM SGNL had been created to archive communications, and reporting linked its use to Mike Waltz and other government-related communications. A federal contract for TeleMessage mobile electronic-message archiving had reportedly begun in February 2023. TeleMessage then suspended its global services after a cybersecurity incident in which attackers claimed to have breached internal systems. Reports about the incident also questioned whether the modified Signal service provided end-to-end encryption while messages were being sent to archival storage or after they were stored. The episode highlighted the difficulty of reconciling secure messaging with mandatory retention and supervisory access.
