@SejalSud It's definitely not a startup, It's role as a platform is probably as important as the internet itself. Edtech platforms bring features and interactivity that enhance the learning experience. I would call YT the mother of all edtech startups though, from Khan Academy to Unacademy
@martyrdison Depends, if they are building up their profile, being a part of a marquee consortium gives them the halo effect. Angels that are sought after, that add value beyond capital like to keep things under wraps so their cred is protected while the company is establishing trust & brand.
