Shashua's doubleAI raises $200M Series A, tops $1B valuation

The startup wants to get paid by sharing in the compute savings it finds, not by seat or subscription.

• doubleAI raised $200M in a Series A co-led by Lightspeed Venture Partners and Bessemer Venture Partners, a round that values the Tel Aviv startup above $1 billion.
• Founded by former Mobileye CEO Amnon Shashua and Shai Shalev-Shwartz, the company builds 'Code Execution Models' that optimize how software runs on CPUs and GPUs without touching the source code.
• Its first model, Maxwell, mathematically verifies every optimization it makes, guaranteeing the rewritten machine instructions preserve the program's original behavior.
• One early customer, video-AI startup LTX, says Maxwell doubled its inference speed, while another saw compute costs drop 67%, according to the Wall Street Journal.
• doubleAI employs about 40 people and plans to charge customers a cut of whatever compute spending Maxwell saves them, rather than a flat fee.
• The launch arrives as one-year H100 GPU rental prices have risen 60% year-over-year, per SemiAnalysis, deepening pressure on AI firms' compute budgets.
• As AI labs' training and inference bills balloon, software that squeezes more performance out of existing chips could matter as much as buying more of them.
