The first 15 minutes of every stream determines whether new viewers stay or leave. Algorithms watch retention past 30 seconds and average watch duration as primary ranking signals. A weak open kills both metrics.

The structure that works: open with a 15-30 second hook that names the show and the value, then immediately move into the highest-energy segment. Avoid the common opening killers: long technical setup ("hold on, let me adjust my mic"), low-energy "hi everyone how are you doing" small talk, scrolling through Discord while people wait.

The hook formula: state what the stream is about, what is going to happen in the first 30 minutes, and one specific thing that will make this session memorable. Examples: "Tonight we're finishing the speedrun under 4 hours. The first attempt starts in 15 seconds." Or "Welcome back to the kitchen — chat picks the dish, I have 90 minutes, let's go."

Practice the open. The first 60 seconds should feel scripted because it is the only segment that needs to be. Everything after can flow.
