About Positron
Positron makes hardware for running trained generative AI models, known as inference. Its first product, Atlas, is built on FPGAs, which are chips whose logic can be reconfigured after manufacture, rather than on a fixed-function GPU. The company says Atlas works with Hugging Face models and OpenAI-style API endpoints, and it has described a later system called Titan built around its own custom silicon. Positron was founded in 2023 and is based in Reno, Nevada.
Positron was founded in 2023 and is based in Reno, NV, United States. It is listed under FPGAs, AI Accelerators. Reported funding is $230M Series B (Feb 2026, $1B+ valuation).

What Positron works on
FPGAs
An FPGA, or field-programmable gate array, is a chip whose internal wiring can be changed after it is made. It contains a grid of small logic blocks, memory blocks and programmable connections. Loading a new configuration file, called a bitstream, turns it into a different digital circuit.
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.
