doubleAI

doubleAI is a frontier lab working on science and engineering problems, and its first product aims at one most AI coding tools ignore: software that is already running. doubleAI's model, Maxwell, is presented as the first Code Execution Model — it observes a live program, identifies the bottlenecks, and rewrites the compiled binary while it runs, verifying each change rather than proposing a patch for a human to merge. The lab describes its two pillars as search in the space of ideas and verification.

Production credibility: doubleAI announced a $200M Series A co-led by Lightspeed and Bessemer Venture Partners, reported at a valuation above $1B, with NVIDIA, Dell Technologies Capital, Pitango, Greenfield Partners and BRM Group also listed as backers on its site. It was founded by Amnon Shashua. Early access to Maxwell opened on 19 October 2026, and the company has said it intends to charge customers a share of the compute savings it produces. One note on the date: most coverage places the round in October 2026, while one source says it closed in November 2025 and October was the public announcement.

Key Features

• Maxwell, a model that operates on running software rather than source files
• Rewrites compiled binaries at runtime to remove bottlenecks
• Verification of each change as part of the loop
• Aimed at compute cost rather than developer productivity
• Stated intent to price as a share of the savings produced
• Research spanning kernel performance, data tooling and hardware design

Ideal Use Case

Organisations whose cloud bill is dominated by a few hot paths — inference serving, data processing, simulation — where a percentage improvement in execution is worth more than faster feature delivery. This is an infrastructure-economics purchase, not a coding-assistant purchase, and it is early access rather than a self-serve product.

How doubleAI differentiates

Cursor and Copilot help a person write code. Moderne and Sourcegraph transform code at rest across a repository. Maxwell's claim is a different layer entirely: the binary, while it executes. If the verification story holds, the buyer is a finance or infrastructure owner rather than an engineering manager, and the pricing follows that. The caveats are stage and opacity — early access, no public pricing, and a lab that publishes research posts rather than product documentation.

FAQ

Q: What does doubleAI do? A: doubleAI is a frontier lab for science and engineering problems. Its model Maxwell watches running software, finds bottlenecks and rewrites the compiled binary at runtime, verifying each change.

Q: What is a Code Execution Model? A: doubleAI's term for a model that operates on software as it executes rather than on source code at rest. Maxwell is presented as the first of them.

Q: How much has doubleAI raised? A: A $200M Series A co-led by Lightspeed and Bessemer, reported above a $1B valuation, with NVIDIA, Dell Technologies Capital, Pitango, Greenfield and BRM also backing the company.

Q: Can I use Maxwell today? A: Early access opened on 19 October 2026. There is no published self-serve pricing; the company has said it plans to charge a share of the compute savings delivered.

Q: Who founded doubleAI? A: Amnon Shashua. The round was announced in October 2026, though one source reports it closed in November 2025 and was disclosed later.

tl;dr

doubleAI is a frontier lab whose model Maxwell rewrites compiled binaries at runtime to remove bottlenecks, verifying each change. $200M Series A co-led by Lightspeed and Bessemer above $1B, founded by Amnon Shashua, early access from 19 October 2026.
