Launching a startup today is easier than ever thanks to powerful AI tools like Cursor, Replit, and Lovable that help founders build and deploy products quickly. However, the key challenge is deciding **what to build first**. A **Minimum Viable Product (MVP)** helps startups test their core idea with real users while minimizing cost, time, and risk. Instead of building too many features too early, a focused MVP allows founders to validate their concept and refine their product based on real feedback.
