THz interconnect technology provider for AI and hyperscale data center applications, AttoTude raises $50 million in Series B funding. This round was led by Mayfield and The Westly Group. Existing investors Sutter Hill Ventures, Canaan Partners, and Wing Venture Capital also participated in the funding round.
Last year, the company raised $30 million in Series A and $11 million in seed found of funding earlier this year. Together, the new funds infused bring AttoTude’s total funding to $91 million.
“The data center infrastructure powering AI workloads is hitting fundamental limits with conventional interconnect technologies,” said Dave Welch, co-founder and CEO of AttoTude. “Our THz platform represents a paradigm shift that solves critical bandwidth, power, and reliability challenges. With Mayfield’s support, we’re accelerating commercialization to meet the explosive demand from AI and hyperscale data center providers.”
The Series B funding will be used to scale manufacturing operations, expand customer engagements, and accelerate product development as AttoTude prepares for volume production. AttoTude is currently working with leading hyperscale and AI infrastructure companies on initial deployments.
“We’re witnessing a fundamental reimagining of data center architectures driven by AI, creating an urgent need for breakthrough interconnect solutions,” said Navin Chaddha, Managing Partner at Mayfield. “AttoTude’s radical innovation in THz technology represents the kind of step-function advancement that occurs once in a decade in the semiconductor industry. We’re excited to partner with Dave Welch, Joy Laskar, and their world-class team to bring this transformative technology to market.”
