You need to do very small launches (The Minimum Viable Launch)

What you need for a minimum viable launch:
It depends on the stage
 
It should start with a tweet
It should start with being helpful
Make it visual
Spend the extra day to make it half as long
Spend the extra day to make the visual easier
Get feedback on it / discuss it with a friend
 
Respond to people
Be helpful
 
Start a newsletter ASAP
Be helpful
 
Always ask, as an audience member: “What am I getting out of this?”
If it’s nothing, don’t post it
 
But be yourself online too
Just post to share
Don’t always post for value
Post for memes
Post cuz it’s funny
 
For a product launch, you just need two things:
A headline that tells a story
An image that completes that story
