Semiconductor Startup Positron Raises $230 Million in Series B Funding
Positron, a semiconductor startup, has recently secured $230 million in Series B funding, according to exclusive information obtained by JS. The company plans to utilize this capital to accelerate the deployment of its high-speed memory chips, which are essential components for AI workloads. Sources familiar with the matter have revealed that investors in this round include the Qatar Investment Authority (QIA), the country’s sovereign wealth fund.
The decision to invest in Positron comes at a time when hyperscalers and AI firms are looking to reduce their reliance on industry leader Nvidia. OpenAI, one of Nvidia’s significant customers, has reportedly expressed dissatisfaction with some of Nvidia’s latest AI chips and has been exploring alternative options since last year. This shift in the market dynamic has created a strategic opportunity for startups like Positron to gain traction.
Qatar, through QIA, has been actively pursuing investments in AI infrastructure to bolster its position in the global economy. The country’s focus on compute capacity and AI services has led to major commitments, including a $20 billion joint venture with Brookfield Asset Management announced in September. This strategic approach aligns with Qatar’s ambition to establish itself as a leading AI services hub in the Middle East.
With the recent Series B funding, Positron has raised a total of over $300 million since its inception three years ago. The company’s first-generation chip, Atlas, manufactured in Arizona, offers competitive performance comparable to Nvidia’s GPUs while consuming significantly less power. Positron’s emphasis on inference computing, crucial for deploying AI models at scale, has positioned the company favorably amidst the growing demand for inference hardware in the market.
Besides excelling in memory capabilities, Positron’s chips have demonstrated strong performance in high-frequency and video-processing workloads. The company’s innovative approach to semiconductor technology has attracted interest from investors and industry players alike, signaling promising growth prospects in the semiconductor market.
