About Positron AI
Founded in 2023 by Thomas Sohmers and Edward Kmett, Positron AI builds hardware and software designed to make AI inference more cost-effective and energy efficient. Its systems are designed around the growing requirements of AI inference, particularly memory capacity, memory bandwidth and power efficiency.

The company's first-generation inference system, Atlas, is already deployed at Oracle Cloud Infrastructure, with more than 50 racks being deployed. Parasail uses this capacity for its inference service, while other Atlas production customers include Jump Trading and i3d.net.
Positrons next generation Asimov silicon is planned to tape out on TSMC N3P at the end of 2026 with production expected in the second half of 2027.
Core offerings include:
- AI inference hardware
- Atlas inference system
- Asimov custom silicon
- Titan inference system
- Energy efficient AI infrastructure
Core Technologies / Products / Services
| Capability/Product | Application/Use Case |
|---|---|
| Atlas | First-generation inference system deployed at hyperscaler scale |
| Asimov | Next-generation custom silicon for AI inference |
| Titan | Inference system combining four to eight Asimov chips |
| LPDDR5X Memory | Provides high memory capacity without relying on constrained HBM |
Leadership Comments
"We spend our lives measuring what AI hardware actually delivers in production, and most inference economics struggle under that scrutiny. Positron's architecture addresses the real constraint, memory, without depending on HBM or advanced packaging for its next generation systems, and the team has already banked real deployment experience with its first generation inside Oracle. That is why I am investing and joining the board," said Dylan Patel, founder and CEO of SemiAnalysis Capital, who joins Positron's board of directors as part of the round.
"The Positron inference architecture balances compute, the enormous required memory bandwidth and extraordinarily large context and weight storage. Its optimized power consumption, cost and density are near ideal for inference requirements of the next evolution of Frontier large language models with trillions of parameters," said Jim Clark, Silicon Graphics Founder and Netscape Co-Founder.
