SANTA CLARA, CALIF. -- Nexthop AI, the leading pioneer of highly efficient AI Networking, announced successful closure of an oversubscribed $500 Million Series B funding round, catapulting the company’s valuation to $4.2 Billion. This round was spearheaded by Lightspeed Venture Partners, with Andreessen Horowitz joining as a major investor, and participation from Altimeter and all existing investors.

“The rapid growth of AI is forcing a fundamental rethink of data center network architecture — and that creates one of the largest infrastructure market opportunities we’ve seen in a generation, with the potential to build a $100B+ company. That conviction led us to invest in Nexthop AI from Day One,” said Guru Chahal, Partner at Lightspeed Venture Partners. “Nexthop is uniquely positioned to become the next great networking vendor by combining hyperscale-grade performance, open software, and a co-development model built in lockstep with the world’s largest AI operators.”

“AI clusters are pushing data center networks to their limits, and networking is now central to overall system performance. Nexthop is purpose-built for this shift, combining deep hyperscale experience with a focus on high-performance and open networking,” said Raghu Raghuram, General Partner, Andreessen Horowitz. “We believe Anshul and the team are tackling one of the most important infrastructure challenges in AI today, and we’re excited to partner with them as they scale.”

Nexthop AI has quickly emerged as a frontrunner in the most advanced AI & Cloud Networking segment. The company delivers both off-the-shelf and highly customized switching solutions built on open source operating systems such as SONiC and FBOSS.

“Our relentless focus on innovation and deep customer partnerships has driven the development of highly customized JDM solutions for the largest operators and cutting-edge turnkey products for NeoClouds. We are thrilled to partner with the world’s leading investors in the AI space, to help scale the company to the next level,” said Anshul Sadana, Founder & CEO of Nexthop AI.

Today, Nexthop also launched a range of products for scale-out, scale-across and front-end applications for cloud and AI data centers. The launch portfolio sets new standards for performance, power efficiency, and deployment speed - very critical metrics in AI infrastructure. The company continues to invest in expanding R&D and infrastructure capabilities to broaden this foundational portfolio to meet the demands of unprecedented growth in infrastructure.
