Enterprises are moving beyond AI experiments and copilots for individual productivity toward the next stage: the Agentic Enterprise, where AI agents drive insights, decisions, and workflows at scale. In this session, Sendur Sellakumar, CEO of Dremio, will outline the enterprise AI maturity journey and show why most organizations are still stuck between prototypes and production outcomes. Through live demos and real-world use cases, you will see how Dremio’s open lakehouse platform provides the intelligent data foundation needed to advance. It delivers semantic consistency, zero ETL federation, autonomous optimization, and built-in governance. Learn how organizations can progress from isolated AI pilots to enterprise-wide impact, and why rethinking data architecture is essential for making AI deliver real business value.
Join Julien Deschamps, Data Product Manager, and Carlos Lopez Hernandez, Product Owner of Dremio at BNP Paribas Personal Finance, as they share how their team is transforming the way data is accessed and consolidated. In this session, you’ll hear how BNP Paribas Personal Finance leverages Dremio to simplify data integration, accelerate insights, and empower business stakeholders with trusted, scalable access to data—without the complexity of traditional consolidation approaches.
Join us for a fast-paced technical deep dive where we peel back the layers of Dremio’s platform and showcase the power behind our latest innovations. In this session, you’ll explore:
Agentic AI – how the Semantic & Context Layer transforms how users interact with data.
Query Engine – a hands-on look at Autonomous Reflections driving next-gen performance.
Catalog – dive into Polaris and Iceberg Clustering to see how Dremio redefines metadata management.
Through live demos and practical insights, you’ll walk away with a clear picture of what exists today, how it all fits together, and why Dremio is redefining the modern data stack.
Open source is at the heart of the modern data lakehouse, shaping how organisations achieve flexibility, interoperability, and performance at scale. This panel brings together leading community members from Apache Iceberg, Apache Arrow, and Apache Polaris to explore the present and future of Lakehouse OSS. Panelists will discuss how these projects are evolving, the challenges they’re addressing, and the opportunities they unlock for building truly open architectures. Join us for an engaging conversation on how open source innovation continues to push the boundaries of what’s possible in data platforms.
As digital sovereignty becomes a critical priority for public organizations, Urssaf Caisse Nationale has launched an ambitious initiative with the creation of its Datafabrique. This program is designed to build a sovereign data architecture that ensures security, quality, and control, while also enabling innovation and agility.
This session will share a concrete case study, highlighting the main challenges faced, the strategic decisions made, and the key lessons learned throughout the transformation.
Join us for The Dremio Iceberg and Agentic AI Experience (Workshop)—a hands-on session designed to show how Dremio simplifies building and managing Apache Iceberg lakehouses while unlocking new frontiers in AI. Through guided exercises, you’ll learn how to quickly implement and operate Iceberg tables in Dremio’s open lakehouse platform, making your data more accessible, governed, and ready for analytics at scale. The workshop will also introduce Dremio’s MCP (Model Context Protocol) server and demonstrate how it enables agentic AI to seamlessly query, reason over, and act on your data. Whether you’re a data engineer, architect, or AI practitioner, this interactive experience will give you practical skills for unifying your data in Iceberg and empowering intelligent agents to put it to work.

Enterprises are moving beyond AI experiments and copilots for individual productivity toward the next stage: the Agentic Enterprise, where AI agents drive insights, decisions, and workflows at scale. In this session, Rahim Bohjani, CTO of Dremio, will outline the enterprise AI maturity journey and show why most organizations are still stuck between prototypes and production outcomes. Through live demos and real-world use cases, you will see how Dremio’s open lakehouse platform provides the intelligent data foundation needed to advance. It delivers semantic consistency, zero ETL federation, autonomous optimization, and built-in governance. Learn how organizations can progress from isolated AI pilots to enterprise-wide impact, and why rethinking data architecture is essential for making AI deliver real business value.
Trusted Data Solutions in sensitive industries such as healthcare and the public sector must combine sovereignty, compliance, and scalability with the ability to integrate diverse data sources.
Danyel Gros and Marcel Just from STACKIT will share insights into how the sovereign cloud foundation of STACKIT and the open lakehouse platform of Dremio work together to provide consistent access, built-in governance, and efficient data management without heavy integration overhead.
This combination will be illustrated through the example of a Medical Data Platform, showing how sensitive information can be managed securely while enabling a scalable and future-proof data foundation for research and healthcare services.
The lakehouse has become the dominant paradigm for modern analytics and AI, but its inherent complexity often frustrates enterprises. In this session, Thomas Zeutschler from BARC takes a neutral analyst’s perspective to explore how the lakehouse has evolved from buzzword to production reality, where the true challenges lie, and how innovations are making life easier for both data engineers and business users. With a special focus on data sovereignty and sovereign cloud platforms such as StackIT, the talk will highlight when a single-platform strategy makes sense and when a multi-vendor approach delivers the best of both worlds. Expect praise, critique, and a few laughs along the way.
In this session, DATEV outlines their data landscape and discuss pre-Dremio challenges. They showcase their current self-service analytics process using Dremio, detailing their technical infrastructure.
Ever felt like accessing production data requires a secret handshake with IT – and maybe some cookies? At Schaeffler, our data scientists decided it’s time to break the cycle. In this session, we’ll share how we’re using Dremio to make large-scale production data AVAILABLE TO ALL – no magic spells or endless helpdesk tickets required.
We’ll take you through:
The not-always-easy journey from “Can I have that dataset, please?” to true data democratization
Two real-world use cases that sparked our transformation, including our motivations and guiding principles
What it looks like behind the curtain
Where we’re heading next – AI, chatbots, and whatever disruptions come our way!
This talk takes you on a journey through the evolution of data transformation—from traditional rollout processes rooted in data warehouses, to modern, automated workflows designed for the lakehouse. We’ll explore practical approaches using Dremio and declarative frameworks like dbt, highlighting how teams can transition toward scalable, maintainable solutions. The session concludes with a look at Agentic AI: what’s already possible today, and where intelligent automation might take us next.
