Session
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.
