The short answer is we didn't find product / market fit. It made some people happy, and was useful to some people, but it didn't make people go out and tell everyone they know to start using it. ShareLaTeX on the other hand was growing organically and had people singing it's praises even when it would sometimes randomly lose 30 minutes worth of your latest changes... (yes really! That's very fixed now though don't worry). ShareLaTeX just filled a much deeper need for people. There are so many other Python/R options out there that we never filled a deep need with DataJoy.

The exception to that is in teaching. It did fill a big need there, but we never managed to make the business model work (long high touch sales cycles, but universities only willing to pay very low prices per class). We also never found a growth model for this.
