Progressive disclosure is an interaction design principle that sequences screens, so users do not feel overwhelmed and inevitably bounce.
Founders should take note of this principle when reaching out to potential employees and investors. Your goal is always to get to the next step, not get hitched after 2,000 words. If you are connecting with someone for the first time, your goal should be to receive a response. Keep things between 50 to 250 words (just like this note).
As Kunu says, do less.
