This latest investment brings AttoTude&#8217;s total funding to $91 million, following its $30 million Series A in 2024 and $11 million Seed round earlier that year.</p>
<p>AttoTude is transforming data center interconnects with the world&#8217;s first THz interconnect over wire, significantly improving bandwidth, reliability, and energy efficiency at a leading cost structure. The company&#8217;s THz platform fully meets the scale up application without the use of photonics by leveraging standard ASIC manufacturing processes to communicate up to 40m.</p>
<p>&#8220;The data center infrastructure powering AI workloads is hitting fundamental limits with conventional interconnect technologies,&#8221; said <a href="https://cts.businesswire.com/ct/CT?id=smartlink&;url=https%3A%2F%2Fwww.linkedin.com%2Fin%2Fdave-welch-b359b630%2F&;esheet=54231399&;newsitemid=20250401188826&;lan=en-US&;anchor=Dave+Welch&;index=2&;md5=5f86cacc00d3c139233d519ef83af64b" target="_blank" rel="nofollow noopener" shape="rect"><b>Dave Welch</b></a><b>,</b><b> co-founder and CEO of AttoTude</b>. &#8220;Our THz platform represents a paradigm shift that solves critical bandwidth, power, and reliability challenges. With Mayfield&#8217;s support, we&#8217;re accelerating commercialization to meet the explosive demand from AI and hyperscale data center providers.&#8221;</p>
<p>The Series B funding will be used to scale manufacturing operations,<i> </i>expand customer engagements, and accelerate product development as AttoTude prepares for volume production.<i> </i>AttoTude is currently working with leading hyperscale and AI infrastructure companies on initial deployments.</p>
<p>&#8220;We&#8217;re witnessing a fundamental reimagining of data center architectures driven by AI, creating an urgent need for breakthrough interconnect solutions,&#8221; said <a href="https://cts.businesswire.com/ct/CT?id=smartlink&;url=https%3A%2F%2Fwww.linkedin.com%2Fin%2Fnavinchaddha%2F&;esheet=54231399&;newsitemid=20250401188826&;lan=en-US&;anchor=Navin+Chaddha&;index=3&;md5=d29dd704a422417ed4b00ca71b071fc0" target="_blank" rel="nofollow noopener" shape="rect"><b>Navin Chaddha</b></a><b>, Managing Partner at Mayfield</b>. &#8220;AttoTude&#8217;s radical innovation in THz technology represents the kind of step-function advancement that occurs once in a decade in the semiconductor industry. We&#8217;re excited to partner with Dave Welch, Joy Laskar, and their world-class team to bring this transformative technology to market.&#8221;</p>
