Proprietary technology

Our technology captures the dynamics of the data that cause predictive models to degrade, increasing the assertiveness of the models built. In this way we reduce defaults, block more fraud, increase sales, etc.

Current technology

Traditional machine learning models are static, developed from existing algorithms on the market that degrade over time.

Low maintenance costs

4kst adaptive models do not require frequent re-training and are easy to integrate with a 100% secure API connection.

High maintenance costs

Static models degrade over time, lose their assertiveness and need periodic updating and retraining.

Lower TCO (Total Cost of Ownership)

We host your models in our cloud so you don't need to invest in hardware or hire machine learning experts.

High TCO (Total Cost of Ownership)

High investment in hardware and an in-house team to develop and maintain the model.
