42AI comes out of stealth with $62.5M and a world model that can predict human behavior
Israeli startup 42AI has exited stealth with $62.5 million in seed funding secured over three years from its founders and Infinity Group. Led by CEO Amit Gal-Or, CTO Ehud Ezra, and Chairman Amir Gal-Or, the company developed a transformer-based behavioral world model to forecast individual decisions in unfamiliar scenarios. Instead of simply extrapolating past actions, the platform maps underlying psychological tendencies into probabilistic decision distributions.
Built with input from psychology experts and 2011 Nobel laureate Dan Shechtman, the system was trained on assessments and biobank records of two million people before scaling to datasets covering nearly 30 million. In practice, it evaluates behavioral data points such as customer support voice sentiment, onboarding steps, and transaction timing without utilizing personally identifiable information.
Deployed across ten large brokerages to manage liquidity and hedging, 42AI generates seven-figure revenues and claims a 0.8 to 0.85 F1 score on trade direction and volume. While exploring expansions into fraud prevention, cybersecurity, and robotics, the founders acknowledge accuracy drops without situational context, alongside ethical questions over brokerages potentially trading against client tendencies.
