I think this is a great idea and a great product considering how fast the whole world is switching to remote work and remote learning. Lots of businesses and schools were already challenged with supporting remote users and there was no one-click solution available in the market. I do like the idea of controlling someone else's screen through the browser since it removes a lot of friction in the process of debugging issues in software-based services.
The business model of integrating with customer support systems like Freshdesk and Zendesk is one of the most obvious paths to the commercial success of this project but you can also consider partnering with schools and other educational institutions.
I've used the demo app and the whole experience is really slick! As a software engineer, I know how challenging it is to implement real-time streaming in browser but you guys did a really great job tackling this!
