It is a waste to spend presentation on things your audience already knows, or already assumes is the case.

• Already knows: common knowledge among informed audiences. A specialized investor who invests in crypto knows the basics of what is going on in that market.

• Already assumes: something that people guess instantly, you IPO-ed both of your 2 previous startups, so the question can she be a startup CEO does probably not need any more time

You can score the obvious points very quickly with a snap reminder slide. Now it is time to move on to things that might surprise the audience (in a good way).

But remember, things can work the other way:

• Already knows: “It is impossible to make good returns in healthcare diagnostics”

• Already assumes: “She looks like she just got out of college, she cannot sell to big pharma”

Put yourself in the shoes of the adience.
