AI developer doubleAI has raised $200 million in a Series A round. Lightspeed and Bessemer co-led the investment, with Nvidia Corp., Dell Technologies Inc. and several others participating. CTech reported that the round values doubleAI at more than $1 billion.
The Tel Aviv-based company, officially AA-I Technologies Ltd., developed an AI model called Maxwell to make software code more efficient. It has also used the model and an internal AI agent for other tasks, including work on a chess challenge and a mathematical discovery.
Maxwell looks for ways to improve a program by analyzing how it interacts with data and the chips running it, according to doubleAI. It supports both graphics processing units and central processing units. The model changes a program’s binary, the machine-generated form that processors run. That allows it to apply optimizations without developers manually changing source code, including while an application runs in production.

In March, doubleAI said Maxwell had rewritten Nvidia’s open-source cuGraph library to reduce hardware usage. The company said 55% of the library’s algorithms ran at least twice as fast. cuGraph lets customers use Nvidia graphics cards for graph analytics, a data science approach used in fields such as supply chain management.
Maxwell also produced an optimized version of the open-source data science toolkit pandas. It ran 38 times as fast on PDS-H, a query speed benchmark. In a more recent project, doubleAI used Maxwell to double the video generation speed of LTX-2.5, a world model.
Earlier this month, an internal doubleAI agent made a discovery about graphs, mathematical structures used in software development. It paired its proof with a Lean file to make the finding relatively simple to verify. DoubleAI also said Maxwell found a chess position in which 63 moves give check, surpassing a record of 60 that had stood for nearly 50 years.
DoubleAI plans to buy 1,000 Nvidia chips
The Wall Street Journal reported that doubleAI will spend half the round on 1,000 Nvidia B300 Blackwell graphics cards. OpenAI Group PBC and Anthropic PBC have also developed models capable of automating research tasks. A few days ago, OpenAI released 722 AI-generated math papers. A month earlier, an Anthropic model created a computer-verifiable version of a famous mathematical proof comprising 13 million lines of code. DoubleAI plans to sell Maxwell to enterprises seeking to reduce the hardware usage of their AI workloads.
