Vibe NLP for Applied NLP
Ines Montani

One of the hardest parts of applied NLP has always been breaking down complex business problems into machine learning components. It's so hard because it requires domain expertise and reasoning about the specific use case, and it's the one thing technology couldn't fix. But what if we could take some of the learnings from AI-powered coding assistants and apply them to solving real-world NLP problems? In this talk, I'll show how we've built powerful assistants and tools to help developers solve NLP tasks using open-source software, and create modular solutions that are small, fast and fully data-private.

Open Source as a Business — Models, Paths, and Practice
Yann Lechelle, Ines Montani, Sylvain Corlay, Alexander CS Hendorf

Open source powers the world's digital infrastructure — from AI research to enterprise data pipelines. But how do you build a sustainable business on it? This panel brings together three figures from the heart of the global open source ecosystem: Yann Lechelle (Probabl), who made the deliberate switch from infrastructure CEO to open source; Sylvain Corlay (QuantStack), whose consulting business is built from and around the core of the Jupyter ecosystem and its maintainers; and Ines Montani (Explosion / spaCy), one of the most influential voices in NLP tooling. Three founders. Three paths. Real answers on what it takes to build — or switch to building — a business in open source.
