About & Trust
We believe that better forecasts lead to better decisions. Our mission is to help societies navigate uncertainty with honest, transparent predictions.
Our Mission
Help societies navigate uncertainty with better, more honest predictions.
Traditional decision-making relies on expert intuition and siloed data. Tier9 aggregates the wisdom of crowds — staff, domain experts, and the public — into clear probabilistic signals that organizations can act on.
We focus on the domains that matter most: climate adaptation, pandemic preparedness, scientific integrity, infrastructure resilience, and workforce transformation. These are areas where early warning and better calibration can save lives and resources.
Our Principles
Trust is the foundation of good forecasting. Here's how we earn it.
Focus on social impact
Every forecast should serve a meaningful purpose. We prioritize domains where better predictions can improve policy decisions and save lives.
Guardrails on harmful topics
We maintain responsible forecasting with ethical boundaries. Some questions shouldn't be asked, and we enforce community standards.
Privacy-preserving question design
We design questions to extract signal without compromising individual privacy or enabling harmful uses of prediction data.
Open, inspectable forecast histories
Every forecast is accountable. Users can see how predictions evolved over time and verify resolution outcomes.
Built by Tier9AI
