AI engineer / researcher (LLM agent focus)

About Mantic

• Mantic is an AI startup based in London.
• Mantic's mission: solve judgmental forecasting to radically improve decision-making. Judgmental forecasting is about making predictions in the absence of good statistical models, often on the topics of geopolitics, business & economics, policy, and technology. Human superforecasters use reasoning and research, and we're building an AI system that does the same.
• We have an unusually strong technical team, coming from previous work at Google DeepMind, Citadel, Foresight Data Machines, the Bank of England, Goldman Sachs, Palantir, the VGG group at the University of Oxford, and the University of Cambridge.
• According to Polymarket, Mantic is "by far the best performing AI forecasting system that we are aware of". Mantic placed 4th / 500+ people in the most recent Metaculus Cup, a leading forecasting competition. (The Atlantic, The Guardian.)
