How do I validate my startup idea and what comes next after validation?

Hey everyone,

I have a startup idea, but I’m not sure how to validate it properly. What’s the best way to check if people actually need what I want to build?

And once it’s validated, what’s next? Should I build an MVP or an SLC (Simple, Lovable, Complete) version, then start marketing and selling it?

Would love to hear how you guys handled this stage, what worked, what didn’t, and what you’d recommend for someone just getting started.

Thanks!
