42AI exits stealth with $62.5M, unveils transformer 'behavioral world model' to predict individual decisions
Israeli startup 42AI announced a $62.5M seed round as it came out of stealth and described a transformer-based 'behavioral world model' that it says infers psychological tendencies from signals (KYC, transactions, calls, etc.) to output probabilities of individual decisions. The company reports deployments at about 10 large brokerages, claims F1 scores of 0.8–0.85 for predicting trading direction/volume and a 98% accuracy measure for trading flows (as the company defines it), and says its datasets include nearly 30 million customer records plus >2 million government/biobank records.
