The origins of Data Science Summit date back to 2014, when the first Data Science Warsaw community meetup was held. It was the popularity of these periodic meetups that contributed to the decision to organize the first edition of the conference, and its success to subsequent ones. Today, DSS is the largest community in Poland centered around the Data Science and AI area.
The main edition of Data Science Summit is the largest independent data science conference in the CEE region. The topics of the event are very broad and cover the entire data area: from ML / AI, through analysis and processing (including Big Data), implementation issues, to visualization (BI) and management topics. It brings together 3,500+ people from the community every year. A companion event is the industry Data Science Expo, where you can meet product and service providers, as well as current recruiting employers.

Check Agenda 2025 - Selected by practitioners, the most interesting speeches on trends, latest solutions and production experiences.

We created an attractive agenda for everyone - professionals and experts as well as decision makers

An event that should be one of the main points on the calendar of anyone associated with the data area

The Data Science Summit explores all current and important threads, such as the security of AI systems, the explainability and interpretability of predictive models, aspects relevant during the research phase as well as the implementation phase

The conference addresses the use of data in the organization in an attractive way for executives - from project manager to board member

DSS is not only interesting speeches, but also inspiring talks, exchange of experiences and a great opportunity to network with fantastic people

All those involved in the development, implementation and maintenance of data solutions will find a lot of interest here

DSS over the past few years has become the largest event of its kind in the CEE region. Here you will meet industry leaders and thousands of others from the *data* community.

It's great that the agenda is divided into as many as 3 formats - online live, stationary and as a VoD library. It's best to be on-site but regardless of how and when you prefer to watch, you're sure to learn a lot here
