For too long, metal recycling has been both financially and environmentally costly—up to 20% of all metal is lost during manufacturing. Because recycling that scrap is so expensive, much of it ends up in landfills. At SUN METALON, we’re changing that. Our zero-CO₂ technology transforms contaminated, low-value swarf into high-value metal—directly on-site. We’re not making new metal—we’re making metal new.

We enable serverless inference via our GPU orchestration and model load-balancing system. We unlock fine-tuning by enabling organizations to size their server fleet to throughput needs, not number of models in the catalogue. See it in action on our public cloud, which offers inference for 10k+ open weight models.

“TELEXISTENCE” is a concept that was first proposed in 1980 by Dr. Susumu Tachi, Professor Emeritus of the University of Tokyo and the chairman of TX inc, which refers to the notion of humans being in a place other than where he or she actually exists and being able to act freely in that remote environment – essentially expanding the presence of human beings – as well as the technological systems that make this possible. Our mission at TX inc is to change robotics, change structures, and change the world. テレイグジスタンス(TELEXISTENCE/遠隔存在)とは、TX incの創業者の一人でTX会長でもある東京大学名誉教授 舘暲氏が1980年に世界で初めて提唱した、人間が、自分自身が現存する場所とは異なった場所に実質的に存在し、その場所で自在に行動するという人間の存在拡張の概念であり、また、それを可能とするための技術体系です。 TX incのミッションは、ロボットを変え、構造を変え、世界をかえることです。

Transcelestial is building the future of Internet Distribution. The ultimate goal is to build a space laser network to deliver a step-change in internet connectivity globally. This will be the fastest way to bring the rest of the world up on the bandwidth and connectivity curve. Right now, we are using the same technology on the ground as a "wireless fibre optics" in a product called CENTAURI. CENTAURI is our mass-produced network device which leverages our proprietary Wireless Laser Communication Technology to create a wireless distribution network between buildings, traditional cell towers, street-level poles and other physical infrastructure. It is the size of a shoe-box, weighing less than 3kg and capable of delivering true fibre-like speeds to customers at fraction of the cost of traditional fibre. There are two versions of devices available - 1 Gbps Full Duplex (4G & Enterprise ready) and 10 Gbps Full Duplex (5G-ready).
