Unlimited vision,

impressive results.

4kst is the result of an innovative vision that combines science, technology and business impact. We are a spin-off from a renowned artificial intelligence research center in Brazil, PUCPR, and belong to the select group of DeepTech companies with science-based technology. Since our founding in October 2017, our mission has been clear:
To help companies make better, more assertive decisions driven by artificial intelligence.

Our journey began in the academic environment, led by researcher Fabrício Enembreck, who, together with Riccardo Lanzuolo, brought 4kst to life. Initially, we dedicated our efforts to developing a "cloud" layer that would transform our technology into an accessible service in the "as a Service" (aaS) model. This step was made possible thanks to the collaboration of experts from PUCPR, such as Jean Paul Barddal and Lucas Loezer, who joined the team as partners.

4kst was born to provide what traditional machine learning services do not. Current predictive models are failing. They simply can't capture the world's ultra-fast changes, leading to massive capital loss due to poor decisions in Credit Scoring, Fraud Detection and Sales. Companies are trapped in an expensive and endless cycle of updating models that are perpetually out of date.

Based on proprietary technology, we build models quickly, with the highest precision on the market, capable of keeping up with changing patterns in real time, with high performance and scalability. For our clients, this means high assertiveness rates and, most importantly, models that don't degrade over time, eliminating the maintenance cost required by current technologies.
