The round was co-led by NEA, Valor Equity Partners, Atreides Management, Andra Capital, Dylan Patel’s SemiAnalysis Capital and Jim Clark. Liberty Global's selection reflects the strategic value it brings through its global technology footprint and experience scaling digital platforms.

Founded in 2023, Positron develops hardware and software designed specifically for AI inference, the stage at which trained AI models process and generate outputs. Its memory-first architecture is designed to lower total cost of ownership and process requests faster by addressing the memory bottlenecks that constrain AI inference.

Positron’s memory-first inference systems use LPDDR5X memory, avoiding constrained HBM and CoWoS supply chains, while achieving more than 90% memory bandwidth utilization. Its Atlas systems can be installed in existing data center architecture without changes to cooling systems.

Bobbie Maltiel, Partner at Liberty Global Tech Ventures, said: "While AI is being adopted by consumers and enterprises at a phenomenal rate, the ability to deliver token usage at the lowest possible cost is key to the full benefits being delivered for society. The Positron team have a relentless focus on this and we are delighted to be joining them on their mission to deliver high-speed AI at the lowest possible cost to businesses and consumers."

The market for inference compute, the computing power needed to run AI models rather than train them, is expected to be worth $1.3tn by 2032 driven by hyperscaler demand*. Positron already counts Oracle, Jump Trading and Parasail among its customers.

Its next-generation custom silicon, Asimov, tapes out in late 2026 with production in the second half of 2027. Asimov powers Titan, a multi-terabyte-memory inference system for long-context and next-generation AI workloads.

Liberty Global Tech Ventures invests in category-defining AI and technology businesses and Positron joins firms like ElevenLabs, XBOW, Legora and Higgsfield in selecting Liberty Global as a strategic investor.
