Nvidia backs Point2’s RF links for AI data centers

By August 10, Point2 said another extension, led by LB Investment with new participation from Arm, had brought total Series B financing to $136 million. Its investor roster already included Nvidia, UMC Capital, Molex and Bosch Ventures. The cumulative round total thus increased by $60 million between the announcements. The $76 million and $136 million figures are not separate sums to add together, and neither identifies Nvidia’s individual contribution.

A report on the Seoul announcement describes the latest backing as a direct Nvidia investment following the earlier NVentures deal. Nvidia’s own announcement does not explain the transaction’s structure or its relationship to the previously disclosed financing.

Radio signals inside a physical connection

Point2’s e-Tube technology uses RF data transmission through a plastic dielectric waveguide, according to its technical description. That makes the medium important: these are guided signals in a physical interconnect, rather than a proposal to broadcast data freely across a server room. The company describes Active RF Cables for links including accelerator-to-accelerator connections.

Turning that approach into usable infrastructure also requires connectors and compatible packaging. In an October 2025 announcement, Point2 described a cable and connector ecosystem developed with Molex and Foxconn Interconnect Technology, including pluggable cables for connections within and between racks.

In its August financing release, Point2 claims ten times copper’s reach at comparable cost, as well as lower power, cost and latency than optics. The release does not provide link lengths, data rates, a test method or itemized pricing that would turn those comparisons into a purchasing calculation. Those remain supplier claims, rather than demonstrated savings for a specified customer configuration.

Point2 is also competing with approaches beyond conventional copper and optics. Its September 2026 conference notice listed AttoTude alongside it in an “Alternate Scalable AI Interconnects” session. The Menlo Park-based interconnect developer describes its own technology as terahertz radios over wire for AI and hyperscale data centers. That establishes another company pursuing non-optical links, without establishing which approach performs better.

Nvidia also has its own optical networking program. In March 2025, it unveiled Spectrum-X Photonics Ethernet and Quantum-X Photonics InfiniBand switches, integrating optical communications into networking switches. That announcement also supported pluggable optical transceivers. Its performance claims concern networking platforms and do not provide a matched test against Point2’s rack-scale links. The investment does not establish a choice to replace Nvidia’s optical strategy.

The next test is deployment

The Seoul forum placed Point2 within a broader startup investment effort. Nvidia also announced planned investments in Motif Technologies, a Seoul AI lab behind the open-weights Motif-3 language model; RLWRLD, a robotics foundation-model developer; and Upstage, a Korean enterprise AI company developing Solar language models and document AI tools. The accompanying reporting says Upstage’s investment is expected in the second tranche of its Series C round. It also reports Motif’s statement that Nvidia is expected to join its bridge financing and that it plans to release Motif-4 with open weights in the first quarter of 2027. Those plans should be distinguished from the Point2 investment Nvidia said it had made.

Nvidia says in its announcement that its Inception startup program already has more than 1,000 Korea-based members, offering preferred pricing, technical expertise and investor introductions. Equity investments deepen its financial ties to selected companies beyond that support program.

For Point2, the unresolved issue is commercial adoption. Its August financing announcement earmarked funds for commercializing active RF cables and near-packaged and co-packaged e-Tube solutions. Named production deployments, qualification results and comparable measurements of reach, power, latency and cost at specified data rates would establish how far that work has progressed. The investment announcement supplies neither that operating evidence nor a commitment to install Point2 links in a named Nvidia system.
