How does Blender make money?

I'm curious to know, how does Blender, the popular open-source software for 3D computer graphics, actually generate revenue? I understand it's a free and accessible tool for artists and creators, but surely there must be some way for the developers to sustain their work and continue improving the platform. Is it through donations, partnerships, or some other innovative monetization strategy? I'd love to hear more about the business model behind Blender and how it manages to stay afloat while offering its services to the public at no cost.
