Would a platform that lets people buy real projects, learn with mentors, and later sell their own work be valuable in tech — or is it destined to fail?

I’ve been thinking about the gap between learning theory and building real-world projects. What if there was a platform where:

You could buy practical, real-world projects to learn from

Mentorship was included, **guiding you through the project ** And once you gain confidence, you could sell your own projects back on the platform

This could create a cycle of learning → building → teaching → earning . Do you think something like this would actually gain traction in the tech world, or would people not find it useful?

What would make such a platform truly valuable for developers, learners, and mentors?
