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.
