Attotude

AttoTude is a semiconductor and data-center infrastructure company building the first wired terahertz (THz) interconnect for AI and hyperscale networking. Its platform pairs the AttoEngine, an ASIC-based THz radio built on standard CMOS manufacturing, with AttoWire, a low-loss dielectric waveguide that carries 200/400/800 Gbit/s per lane over reaches up to roughly 40 meters, delivering the bandwidth density of optics without the cost, power, and complexity of photonics. Founded to relieve the interconnect bottleneck in everything-to-everything AI clusters, the company has raised roughly $143M across seed, Series A, Series B, and Series C rounds. This is a hardware company with no public API, developer portal, or SDK; the profile below is enriched only with the identity and domain-security facts the pipeline could verify.

Attotude is profiled on the APIs.io network. Tagged areas include Company, Semiconductors, Data Center, Interconnect, and Terahertz.

Attotude’s developer surface includes engineering blog and 2 more developer resources.
