# Positron AI

> Positron AI designs purpose-built inference hardware for transformer models, aiming to make Nvidia GPUs optional for running large language models at production scale. Its first product, Atlas, ships from US fabs and claims roughly 3x lower latency and 4x better performance-per-watt versus an H100 system.

- **Founded:** 2023
- **Headquarters:** Reno, Nevada, United States
- **Founders:** Thomas Sohmers (Co-founder, CTO (Thiel Fellow)), Barrett Woodside (Co-founder, Chief Business Officer), Edward Kmett (Co-founder, Chief Scientist)
- **Team size:** ~62 employees with 400+ combined years of AI, silicon, systems, and cloud experience
- **Products:** Atlas, Asimov, Titan
- **Notable:** Reached unicorn ($1B+ valuation) 34 months after founding., Shipped first-generation Atlas accelerator in roughly 18 months., Reported ~3x lower end-to-end inference latency vs an H100-based system in evaluated workloads.

## Products & services

- **Atlas** — First-generation LLM-inference appliance. Eight-card air-cooled system supporting models up to 500B parameters. Shipping to production data centers, fully fabricated in the United States.
- **Asimov** — Next-generation custom inference silicon with 2TB+ memory per accelerator. Tape-out planned for late 2026, production early 2027. Designed for 5x more tokens-per-watt than Nvidia Rubin.
- **Titan** — Forthcoming Asimov-based system - 'superintelligence in a box' - with 8TB+ memory per node and 4x Asimov chips. Slated for 2027.

## Achievements

- Reached unicorn ($1B+ valuation) 34 months after founding.
- Shipped first-generation Atlas accelerator in roughly 18 months.
- Reported ~3x lower end-to-end inference latency vs an H100-based system in evaluated workloads.
- Raised $305M+ in total funding across Seed, Series A, and Series B.
- Atlas is fully fabricated and assembled in the United States.

## Latest updates

- **2026-02** — Closed $230M Series B at $1B+ valuation, co-led by ARENA Private Wealth, Jump Trading, and Unless.
- **2025-07** — Closed $51.6M oversubscribed Series A.
- **2025-02** — Mitesh Agrawal (formerly Lambda COO) joined as CEO; $23.5M seed announced.
- **2023** — Company founded in spring 2023 by Sohmers, Woodside, and Kmett.
