About Tenstorrent
Tenstorrent designs AI processors and licenses RISC-V and AI intellectual property to customers building their own silicon. Its Wormhole and Blackhole accelerator cards are built around Tensix compute cores, and Blackhole adds on-die RISC-V cores for orchestration without a separate host processor. The company also sells developer systems such as the TT-QuietBox and larger Galaxy servers. Tenstorrent is led by chip architect Jim Keller and emphasizes open-source software and the royalty-free RISC-V instruction set.
Tenstorrent was founded in 2016 and is based in Austin, TX, United States. It is listed under AI Accelerators, HPC & AI Systems, CPUs & RISC-V. Reported funding is ~$800M round in progress at $3.2B valuation (Fidelity-led, Nov 2025); $1B+ raised.

What Tenstorrent works on
AI Accelerators
An AI accelerator is a chip, or a part of a chip, designed to run machine learning faster or with less energy than a general-purpose processor. The category includes GPUs, TPUs, neural processing units (NPUs) and chips from many startups.
HPC & AI Systems
High-performance computing (HPC) means using very large clusters of processors working together to solve problems that one machine cannot handle in a reasonable time. These clusters are called supercomputers. They run weather models, physics simulations and, increasingly, AI training.
CPUs & RISC-V
A CPU, or central processing unit, is the general-purpose chip that runs a computer. It reads instructions, does arithmetic and logic, and decides what happens next. Every phone, laptop and server has at least one.
