About

Founded in the spring of 2023 and headquartered in Reno, Nevada, Positron is an AI inference hardware company on a mission to make LLM inference efficient and affordable. The company's first product, Atlas, is the world's first LLM-inference-first accelerator—built in 18 months, manufactured in the United States—delivering 3x lower end-to-end latency and 1/3rd the power consumption of comparable NVIDIA H100 systems. Positron's technology is used by networking, gaming, content moderation, CDN, and Token-as-a-Service companies. The company has raised over $300 million in total funding, including a $230 million Series B at over $1 billion valuation, and is developing its next-generation Titan silicon platform to further extend its inference efficiency advantage.
