Behavioral Intelligence Layer for AI
By William Lebovics · 2026-07-07

AI can write your emails. It still can't tell you what a human will do next.
42AI is fixing that.
The Tel Aviv + NYC lab built a Behavioral Intelligence Layer — models that predict human behavior in volatile, never-before-seen situations. Not by pattern-matching the past, but by modeling the actual drivers of behavior.
The results: 0.7–0.8 F1 in novel scenarios. 2–2.5x state of the art.
Two engines power it:
→ A Large Behavioral Model that predicts how a person decides
→ A Behavioral World Model that predicts how behavior evolves over time
First stop: financial risk management — where predictions are verified in real time and being wrong is expensive. Live with an international CFD broker, a global gaming studio, and a 10+ enterprise pipeline. Behavioral data on 15M+ individuals.
Behind it: founders with $2B+ in exits, the Technion's Vice Dean of AI, and Israel's top PTSD expert.
Prediction was a soft science. They're making it an engineering problem.
$20M raise coming soon. Watch this one.

Frequently Asked Questions
What is 42AI's Behavioral Intelligence Layer?
42AI built a Behavioral Intelligence Layer — models that predict human behavior in volatile, never-before-seen situations by modeling the actual drivers of behavior rather than pattern-matching the past. It's powered by a Large Behavioral Model that predicts how a person decides and a Behavioral World Model that predicts how behavior evolves over time.
What are 42AI's prediction results?
42AI achieved 0.7–0.8 F1 in novel scenarios, which is 2–2.5x state of the art.
Where is 42AI located?
42AI is a Tel Aviv + NYC lab.
What is 42AI's first application?
Financial risk management is 42AI's first stop — where predictions are verified in real time and being wrong is expensive. They are currently live with an international CFD broker, a global gaming studio, and have a 10+ enterprise pipeline with behavioral data on 15M+ individuals.
Who are the founders of 42AI?
42AI's founders include individuals with $2B+ in exits, the Technion's Vice Dean of AI, and Israel's top PTSD expert.
