Overview

Mavenir Systems was an American telecommunications software company headquartered in Richardson, Texas. Founded in 2005 by Rashad Ali, the company developed software for mobile operators seeking to move voice, video, messaging, and communications services onto Internet Protocol-based network architectures. Its portfolio centered on mobile communications infrastructure rather than consumer electronics: IP Multimedia Subsystem software, Voice over LTE, Voice over Wi-Fi, rich communications services, messaging infrastructure, signaling, mobile gateways, and related service-enablement technologies. The company grew through venture financing, acquisitions, operator deployments, and partnerships. It raised $17.5 million in December 2008, followed by a $13.5 million round in June 2010 backed by Alloy Ventures, Austin Ventures, and North Bridge Venture Partners. A later $40 million financing round, supported by existing investors and Cross Creek Capital, brought reported cumulative funding to $105 million. Its rapid expansion earned first place on the Metroplex Technology Business Council's Fast Tech list in 2010 and second place the following year. Mavenir expanded its capabilities through acquisitions. In May 2011 it acquired Airwide Solutions, a Massachusetts-based provider of mobile messaging and wireless-infrastructure software. In November 2014 it acquired Stoke, a company focused on mobile and security gateway technology. In January 2015 it acquired Ulticom for $20 million, adding signaling software to its portfolio. These transactions broadened Mavenir Systems from a specialist in mobile communications applications and IMS-related services into a more extensive network-software supplier. Its commercial activity was closely associated with the transition from legacy circuit-switched mobile voice to all-IP communications. In 2012, Mavenir supplied VoLTE technology to MetroPCS. It subsequently partnered with Radisys on VoLTE deployments in Europe and the United States, and in 2014 supplied the IMS WebRTC gateway used by T-Hrvatski Telekom in connection with its Terastream initiative. T-Mobile launched a VoLTE service in July 2014 using an IMS voice solution developed by Mavenir Systems. The company also worked on a VoWi-Fi application for 3UK and released a mobile voice-and-messaging client intended to support operator-branded VoLTE, VoWi-Fi, and RCS experiences. Mavenir Systems became publicly traded on the New York Stock Exchange in November 2013. Its initial public offering was priced at $10 per share and raised approximately $44.5 million. The public-company period was short-lived. In March 2015, Mitel announced an agreement to acquire Mavenir Systems for $560 million, and the transaction became effective in April 2015. Mavenir Systems consequently ceased to exist as an independent company. The Mavenir name later reappeared in a new corporate structure formed through the combination of Xura, the Mavenir Systems business acquired by Mitel, and startup Ranzure; that later company is distinct from the original Mavenir Systems entity covered here.

History

Mavenir Systems was established in 2005 in Richardson, Texas, by Rashad Ali. Under president and chief executive Pardeep Kohli, it developed software for mobile-network operators at a time when the telecommunications industry was moving from circuit-switched voice toward IP-based communications. The company's focus was on enabling operators to deliver voice, video, messaging, and richer communications services through software-defined network components and IMS architectures. The business financed its expansion through several venture rounds. It completed a $17.5 million financing in December 2008 and raised another $13.5 million in June 2010 from Alloy Ventures, Austin Ventures, and North Bridge Venture Partners. A subsequent $40 million round backed by earlier investors and Cross Creek Capital brought reported total funding to $105 million. Its growth was recognized by the Metroplex Technology Business Council, which ranked Mavenir first on its Fast Tech list in 2010 and second in 2011. Mavenir used acquisitions to broaden beyond its initial communications-software base. In May 2011 it bought Airwide Solutions, a Massachusetts company active in mobile messaging and wireless Internet infrastructure. The transaction strengthened Mavenir's messaging and service-enablement capabilities. The company also pursued industry partnerships. In February 2013 it worked with Radisys on VoLTE deployments in Europe and the United States, and in April of that year it was elected to the Board of Governors of 4G Americas. Mavenir opened a user experience center in Zagreb, Croatia, in April 2013 to demonstrate emerging VoWi-Fi, VoLTE, and RCS products to operators and partners. The company entered the public markets in November 2013 through an initial public offering on the New York Stock Exchange. Shares were priced at $10, and the offering raised approximately $44.5 million. Its commercial activity during this period reflected the industry's early adoption of all-IP mobile voice. Mavenir provided VoLTE service technology to MetroPCS in 2012. In February 2014 it supplied an IMS WebRTC gateway to T-Hrvatski Telekom for the operator's Terastream service-delivery initiative. In May 2014 it released a handset and tablet client for mobile voice and messaging, designed to help operators package and differentiate VoLTE, VoWi-Fi, and RCS services. It also developed a VoWi-Fi application for 3UK, aimed at allowing customers to place calls and send texts over Wi-Fi when cellular service was unavailable. In July 2014, T-Mobile launched VoLTE using an IMS voice solution developed by Mavenir Systems. Mavenir continued its acquisition program late in its independent existence. It acquired Stoke in November 2014, adding mobile and security gateway capabilities, and acquired Ulticom in January 2015 for $20 million, adding signaling software. In March 2015, Mitel announced that it would purchase Mavenir Systems for $560 million. The deal became effective in April 2015, bringing the original Mavenir Systems company to an end as an independent public business. The Mavenir name later returned in a different corporate entity. A subsequent company was formed through the combination of Xura, the Mavenir Systems business acquired by Mitel, and startup Ranzure. That later organization should not be conflated with the original Mavenir Systems entity, which operated from 2005 to 2015.
