NS1 Closes Series D Round from Energy Impact Partners, Bringing Total Funding to $125M

$40M Round will accelerate innovation in modern application and access network solutions that power the connected economy

NEW YORK — July 14, 2020 NS1, the leader in modern application and access networking, today announced that it has raised a $40 million Series D venture round led by Energy Impact Partners (EIP) with participation from existing investors, bringing the company’s total funding to $125 million. The investment, a testament to NS1’s growth, will support the company’s continued innovation and development of modern foundational technologies that power the connected economy.

Though IT modernization trends were well established, recent events have highlighted the importance of high-performing resilient applications and the critical infrastructure technology that supports them. With legacy internet and networking solutions under strain during the COVID-19 pandemic, NS1’s software-defined solutions provided the flexibility and scalability to keep its customers resilient and people connecting, streaming, innovating, and moving the world forward.

“The hyper-connectivity of today’s world has made IT transformation a business imperative. Meeting this demand depends on reliable IT operations and trusted technology partnerships,” said Bask Iyer, Chief Information Officer and Chief Digital Transformation Officer for VMware. “Working with NS1 to implement its managed DNS has helped us build a resilient, more secure and high performing network that improves customer experience, IT efficiency and application reliability.”

Past investments from Cisco and Dell Technologies Capital created opportunities to extend NS1’s market reach and magnify the company’s distribution channel. The most recent round of funding, which represents a significant increase in valuation for the company, will allow NS1 to more aggressively invest in product innovation, and expand the company’s engineering capacity so it can continue to develop market-leading solutions that power the connected economy.

NS1 started 2020 with a rapid influx of new customers. In the first quarter, new customer bookings grew 159% year over year. The company now serves more than 600 enterprise customers, including many of the largest brands and most trafficked applications, such as LinkedIn, Dropbox, Salesforce, The Guardian, TomTom, and Pitney Bowes. And demand for NS1’s foundational technologies continues to accelerate as more organizations are modernizing application and access networking stacks in order to address the continued pressure to support new approaches to work and customer engagement.

“There is heightened urgency to expedite IT modernization. Five-year projects are being condensed to one-year, and the only way to deliver on these aggressive timelines is by unlocking leverage in foundational application and networking infrastructure,” said Kris Beevers, co-founder and CEO for NS1. “This additional investment at a time of rapid growth at NS1 helps us capitalize on the market opportunity to meet the escalating demand for the modern foundational technologies used by every business, enabling them to quickly adapt to changing environments, more effectively control costs, and deliver reliable, secure, and exceptional user experiences.”

Shawn Cherian, partner at EIP, will join NS1’s Board of Directors as part of the round. Cherian said that EIP’s investment in NS1 represents a growing appetite from the firm’s limited partners to integrate with category-leading companies and invest in enterprise SaaS solutions. He cited NS1’s role in meeting connectivity requirements generated by the rapidly increasing number of connected devices as a primary area of growth.

“As enterprises shift to the cloud and their environments become more complex, fundamental infrastructure solutions, like those provided by NS1, will play a critical role in allowing companies to expand more effectively,” said Cherian. “NS1 is the leading next-generation DNS platform and has defined the standard for performance, resilience, and scale, which will continue to have broad applicability for internet services and solutions across verticals.”
