Student projects are great, but for me to invest my time and effort into using just about anything (especially something that is supposed to store my notes), I do need to see a stable long-term sustainable business. Incidentally, that also excludes most VC-funded companies, because these are neither long-term nor sustainable and usually have a user-facing lifespan of 3-5 years.
