15-30 Seconds
Founders, people say an investor will look at your pitch deck for an average of 3 minutes. It's much worse than that.
The average includes some who spend a lot of time. Most will take a glance and move on.
You have 15-30 seconds to get an investor's attention. Then they decide if they want to spend more time on you.
It may not be fair. It is the reality.
