The chip company betting that the fastest way through an AI data center is a radio wave in a plastic tube - not copper, and not light.
The wordmark of a 51-person outfit in San Jose. Behind it: founders out of KAIST, Marvell, Finisar and Samsung, and a cap table that runs through NVIDIA, Bosch and Molex.
Here is an inconvenient fact about the AI boom. The chips get all the attention - the GPUs, the accelerators, the eye-watering price tags - but a data center is not one big chip. It is thousands of them, and every single one has to talk to every other one. The talking happens over cables. And the cables, it turns out, are where the trouble is.
Copper is cheap and reliable, but it runs out of reach fast, and the faster you push it the shorter the distance it can go. Optics - the lasers and fibers that carry the internet across oceans - go the distance, but they cost a lot, burn a lot of power, and have this inconvenient habit of failing when the laser dies. As AI clusters get bigger, the machine spends more and more of its energy budget just moving bits between chips. That is the interconnect wall, and it is not a metaphor. It shows up on the power bill.
Point2 Technology, a fabless semiconductor company headquartered on Century Center Court in San Jose, exists because its founders looked at copper and optics and asked a slightly heretical question: what if there is a third option? Their answer sounds almost too simple. Send the data as a radio-frequency signal, and route it not through a wire and not through glass, but through a thin plastic tube. They call the platform e-Tube, and the cables it makes Active RF Cables.
The company traces its roots to a research lab at KAIST in South Korea, and its founding team pulls from Marvell, Finisar and Samsung - which is to say, people who have spent their careers on the unglamorous physics of moving high-speed signals from one place to another without wrecking them. That is the sort of pedigree that makes an unfashionable idea worth a second look.
The pitch, roughly, is that RF-over-plastic-waveguide gets you the reach of optics with the simplicity and cost of copper, minus the lasers. The company's own numbers put e-Tube at about ten times the reach of copper, lighter, thinner, lower-power and lower-cost - and with no lasers to fail. Numbers like that always deserve a raised eyebrow until they hold up at scale. But the strategic logic is clean: bet against the bottleneck everyone else is ignoring.
Every high-speed link inside a data center is a trade-off between how far it can go, how much power it burns, and how much it costs. Point2's whole thesis is that a fourth variable - the medium itself - has been under-explored.
Cheap, dead-simple, reliable. But reach collapses as data rates climb - fine for short hops, a problem for big clusters.
Goes the distance at high bandwidth. But it is expensive, power-hungry, and depends on lasers that can - and do - fail.

For a 51-person company, Point2's cap table is unusually blue-chip. When a chipmaker (NVIDIA), a tier-one automotive supplier (Bosch), a connector giant (Molex) and a foundry (UMC) all invest in the same interconnect, it is worth asking what they each see.

If you run a hyperscale data center, the appeal is direct: pack more accelerators into a cluster without the cable power and cooling load growing faster than the compute you are adding. Point2's chips and cables are pitched as a way to keep scaling the fabric that ties GPUs together - the part that quietly caps how big a training run can get.
If you build networking or cabling equipment, e-Tube and the retimer SoCs are components you can design around - a supply of the mixed-signal silicon that makes 800G and 1.6T links work. That is why a connector company like Molex is on the cap table rather than just watching from the sidelines.
And if you build cars, the same trick - lots of bandwidth over a light, cheap, laser-free link - starts to look interesting for the tangle of sensors and compute inside an autonomous vehicle. Bosch's investment is a tell that Point2's platform is not a single-market story.
There is also an energy argument, and Point2 leans on it: the company was named a BloombergNEF Pioneer for sustainable data-center infrastructure. Cutting the power a cable draws is a smaller headline than a new reactor, but at data-center scale the arithmetic adds up.
