Better estimates through empirically validated predictions
Improve estimates of project costs, investment value and financial risk through context-dependent risk distributions.
Our method automatically selects the most relevant historical cases based on their predictive value and provides insight into the key predictive factors. Predictive performance has been tested through rigorous out-of-sample validation.
Applications: infrastructure, real estate and urban development, energy transition, public investments, and macro-financial risks
An independent, evidence-based perspective.








Empirically validated forecasts across three domains
Dike reinforcements
50%
better than projectteam estimation
lower prediction error in early P50/P80 estimates; out-of-sample validated.
Land prices
38%
lower downside-risk estimation error
Out-of-sample validated on holdout-set of 20 year
Interest rates
68%
lower downside-risk estimation error
Validated in backtests since 1950, while preserving coverage
We measure forecasting performance on data that was not used to develop the models.
Early estimates and risk assessments often lack context
Many early estimates and risk assessments still rely heavily on internal assumptions, static benchmarks or limited historical comparison. That makes it harder to see downside risk clearly, especially when project context and macroeconomic conditions matter.
Some domains where we add value
Infrastructure
Use top-down, feature-based Reference Class Forecasting alongside detailed bottom-up engineering estimates to assess whether expected project costs are consistent with empirical outcomes
Dike reinforcement cost estimation
Read how we apply RCF-AI, or AI-enhanced Reference Class Forecasting, to dike reinforcement projects.
This method helps to obtain better grounded and context dependent cost estimates.

Our approach
AI-driven Reference Class Forecasting
Our models combine reference class evidence, advanced machine learning algorithms, project-, location- and macro economic context to reveal the key drivers of risk and value. This helps us to create a validated, modern variant of Reference Class Forecasting.
We call this method Predictive Reference Class Retrieval (Predictive RCR). It enables us to identify both the drivers that matter and the dynamic, context-specific reference classes that are most relevant for the intended purpose, based on demonstrated predictive relevance.
As a result, the relevant historical evidence can depend entirely on the context; whether it involves comparable infrastructure projects, locations, or historical economic regimes. We make transparent both which reference observations and which contextual factors and underlying drivers determine the forecast, while rigorous out-of-sample validation tests whether these relationships also hold beyond the data used to develop the models.
- Context-specific reference class evidence
- AI/ML-enhanced forecasting
- Rigorous out-of-sample validation
- Explainable AI and visible drivers
- Empirically grounded forecasts and risk assessments
