COMPANY PROFILE

Meet Positron.

 
 
 

HQ: Reno, NV

Leadership: Mitesh Agrawal, Thomas Sohmers

Website: positron.ai

Opportunity: Building memory-first hardware, systems, and software for inference, focused on workloads where usable memory bandwidth, capacity, power, latency, and total cost of ownership drive the result. Atlas is shipping today; Asimov and Titan extend the architecture toward larger models, longer contexts, and persistent workloads.

Vision: Make advanced AI more affordable and deployable through cost and energy-efficient inference systems that fit standard, air-cooled data centers and work alongside existing GPU infrastructure.

Status: Active

QUICK FACTS

> First partnered with Valor in 2025.

> Founded in 2023, Positron designed, built, and shipped its first product—Atlas, an accelerator purpose-built for LLM inference—in 18 months, with a team of 15 and less than $12M raised.

> Atlas is shipping today, supporting models of up to 500B parameters and delivering more than 4x performance per watt and 3x performance per dollar versus NVIDIA Hopper systems, with 3x lower latency in production workloads.

> Positron's next-generation silicon, Asimov—taping out soon—targets up to 2.3TB of memory per chip and 5x tokens per dollar and per watt versus NVIDIA's Rubin generation, and will power the company's Titan systems coming in 2027.
