doubleAI unveils Maxwell, a code-execution model that optimizes software at runtime

doubleAI, the Israeli AI venture founded by Prof. Amnon Shashua, introduced its first product, Maxwell, in early October 2026. Maxwell is described as a “code execution model” that continuously analyzes a running program, the hardware it uses, and the data flowing between them. Unlike large-language models that generate source code, Maxwell modifies machine-level instructions while the software is executing, preserving the original source code. A built-in verifier mathematically proves that each optimization leaves program behavior unchanged, and the system operates on both CPUs and GPUs.

After stepping down as CEO of Mobileye and ending his roles at AI21, Shashua launched doubleAI, which remained in stealth until the recent announcement. The company raised a $200 million Series A round co-led by Lightspeed Venture Partners and Bessemer Venture Partners, with participation from Dell Technologies Capital, NVIDIA, Greenfield, Pitango and BRM. The financing valued doubleAI at more than $1 billion, and the firm now employs roughly 40 people.

doubleAI reports that Maxwell has accelerated data pipelines by more than 38 times and AI inference kernels by over 4.5 times on real-world workloads. The company also disclosed that it solved the “Longest Path Problem” – a graph-theory challenge with practical relevance to quantum-computing error correction and microchip miniaturization – for a cost under $2,000. These performance figures have not been independently verified, and the announcement provides limited detail on test hardware or baseline comparisons.

Shashua said the technology represents a shift by acting as a hardware agent rather than merely a code-based tool for programmers, positioning Maxwell as the first AI that works for the machine. Yair Snir, managing partner at Dell Technologies Capital, noted that the fund chose to back doubleAI because it develops its own models and delivers rapid, novel breakthroughs in computing efficiency, underscoring Israel’s role in pioneering such innovation.
