Why MVP Development Is Critical for Startups

One of the biggest mistakes startup founders make is building too many features before validating their idea.

Benefits include:

• Early customer feedback
• Better product validation
  
  

Example

Instagram initially focused only on photo sharing.

Features such as:

• Reels
• Shopping
• Messaging
  
  

were added years later.

The same approach helps startups launch faster and improve based on real customer feedback.
