Most common startup mistakes

Tip 1 - Keeping it a big secret

Let's face it, your idea is no cure for cancer and keeping it a secret is not a wise move. Tell everyone about it. Sooner you find out if people want it or not better it is. Stealth mode is an excuse to not want real feedback. 

Tip 2 - First Impression is the Last Impression

This doesn't mean that there cannot be any bug, you can launch in stealth mode while keeping it public beta to let the users know that you're still in a phase of improvement.

However, this is really necessary that your first time visitor should get value and understand the concept behind your startup.
 

Tip 3 - Hiring Too Quickly

Hiring Too Quickly
As an entrepreneur, you are naturally eager to move fast and build a big business. Not only that but you are by nature impatient, no matter how fast you’re moving. That’s partly what makes you who you are; and why you don’t fit into the normal routine of a corporate job.

Inevitably you make the mistake of hiring someone too quickly. Just don’t do it. Listen to your hunch. Take your time on hiring – it’s the single most important investment you make.  Do it carefully.
