An Israeli startup says it can model what a person is likely to do next, and brokerages are paying for it. 42AI emerged from stealth on Monday with 62.5 million dollars in seed funding and a product it calls a behavioural world model, initially deployed at what it says are 10 large brokerages to help manage liquidity, margin requirements and hedging exposure.
The method differs from ordinary behavioural prediction. Rather than extrapolating from past trades, 42AI says it infers underlying psychological tendencies from how people handle apparently unrelated interactions, onboarding, know-your-customer processes, support calls, transfers and sentiment in conversations, and converts them into mathematical trait representations fed into a transformer based model that outputs probabilities for decisions under new circumstances. The company says it first studied thousands of people through psychological assessments and behavioural scenarios, then added government and biobank datasets covering more than 2 million people, and that its customer datasets now cover almost 30 million people. It says the model needs no personally identifiable information, while still building individual behavioural profiles from linked customer activity.
The performance claims are the company’s. 42AI cites a 98 percent accuracy figure that its chief executive clarified measures whether trading flows fall within a predicted range rather than whether individual trades were predicted, and F1 scores of 0.8 to 0.85 for predicting trading direction and volume. It says revenue is above seven figures without specifying a number, and that one brokerage generated approximately 30 million dollars in additional value through dynamic hedging. None of these figures is corroborated by a named customer.
The funding also needs reading carefully. The 62.5 million dollars came from the founders and Infinity Group over three years and was not entirely raised from external investors. Infinity was founded by the father of chief executive Amit Gal-Or, who is also 42AI’s chairman and a co-founder. The company now plans to raise further money and is exploring gaming, fraud prevention and cybersecurity applications. Its founders acknowledge the obvious concern, that a brokerage able to anticipate its own customers’ behaviour could use that knowledge against them, and point to regulation, monitoring and an internal ethics committee.
