The simplest version of your product that still solves the core problem. Ship fast, learn from real users, then improve. Don't build everything at once.
POC - Proof of Concept
A small test to prove an idea actually works before investing serious time or money. It's not a product—it's evidence that building the product makes sense.

Wireframe
A basic sketch showing the layout and structure of a page without any design polish. Think blueprint, not finished building. It's about where things go, not how they look.
