Have you checked out Overleaf? I would say they are proof that there is definitely a market. My university (40k students, 8k employees) has a deal with them where all students and employees get access to premium features, and they probably pay a decent chunk of money for that. They have published a list of institutions using Overleaf here: https://www.overleaf.com/for/universities https://www.overleaf.com/for/universities
