Gatsby's really fun to use developing small apps, and their docs make it easy to get started with Gatsby, React AND front-end in general. They've created a good overall experience for beginners, which could create a decent user base.

That being said, the path to monetization seems hairy (competitive market with many free options, the previously mentioned fact that Gatsby's overall goal is to generate portable files). Is there any way that this is some bizarre VC effort to fund open source or do something nice? Or is that excessively wishful thinking?
