About us
We turn complex data into clear decisions.
ARST Data started as a used-vehicle valuation platform for 14 European markets. We work with our own aggregated, validated market data and our own statistical model, which estimates the market value of each vehicle from comparable vehicles. We measure accuracy in every cycle.
Mission
Market value and residual value, with figures you can check.
We value used vehicles in 14 European markets and project their residual value over 6 years. It is built for those who buy, finance, insure or buy back cars: dealers, leasing and rental, financial institutions and insurers.
We measure each country's accuracy in every cycle, and every valuation carries its P10–P90 band. Beyond the valuation tool: market report, derived data, portfolio monitor and macro and insurance dashboards.
Vertical specialization
We focus on used vehicles in Europe and on the data that explain them: interest rates, inflation, registrations and insurance.
Quantitative rigor
Every model is validated before it is published. We do not publish figures we cannot defend with numbers.
Up-to-date data
Data and models are updated automatically and periodically.
No conflicts of interest
We are independent. No product distributors, no hidden incentives. We work so you can decide with data.
How we work
How we build our models and datasets.
Every step, from the data to the final estimate, is designed so the result is rigorous and reproducible.
Our own market data
We work with our own aggregated, validated market data and with public macroeconomic indicators.
Data quality
We review and standardize makes, models, trims, and equipment before using them. A model is only as good as the data that feeds it.
Proprietary model
Our own statistical model estimates the market value of each vehicle from comparable vehicles, at the finest level of detail the data allow, and gives every estimate an interval.
Validation
After every training run we measure accuracy; the result is available on request for professional clients. It is a statistical estimate, not a professional appraisal.
Products
Several products. One data foundation.
Every ARST Data product draws on the same data foundation, which keeps every layer of analysis consistent.
