Cradlepoint has secured $89m in series C funding led by TCV.
The growth-stage investment will fuel Cradlepoint's product initiatives in SDN, 5G wireless broadband and enterprise IoT.
Ted Coons, General Partner at TCV, and Doug Gilstrap, Venture Partner at TCV, have joined the cloud-based network provider's board of directors.
Cradlepoint has over 15,000 customers and 1.4 million units deployed worldwide, and has achieved over 40% compound aggregate growth rate (CAGR) for the last three years.
The firm provides 4G LTE network solutions for enterprises, governments and mobile operators. Its customer base includes 50% of Fortune 100, 75% of the world's top retailers, and 25 of the largest US cities.
"Cradlepoint has established a strong foundation in cloud-managed 4G LTE network solutions," said George Mulhern, CEO of Cradlepoint.
"The investment by TCV and its experience in guiding disruptive companies will allow us to build on this foundation to capitalise on the opportunity in front of us as digital transformation drives WAN transformation.
"SDN, 4G/5G wireless broadband, mobile networking and IoT technologies will all play a pivotal role in the new connected enterprise, and we are well-positioned to lead the way."
Digital transformation is accelerating cloud, mobile and IoT adoption. According to a report by IDC, the burgeoning market for SDN in the WAN (SD-WAN) is projected to reach $12.5 billion by 2020, spurred on by the need for more agile, automated and available networks and a direct result of digital transformation.
"By 2020, the number of people, vehicles, and things connected to the enterprise network will start to dwarf fixed branch sites," stated Eric Hanselman, chief analyst at 451 Research.
"This dramatic shift in the volume and variety of connections will force the enterprise WAN to become more cloud-orchestrated, software-defined and wirelessly connected and has already started to usher in an entirely new network security model.
"With this investment by TCV, Cradlepoint now has the potential to become a major player in wide-area networking for the connected enterprise."
