The hook is the first beat on our founder build-in-public video page. Vyra has the transcript and a description of every scene, so you can point at the moment by what's in it.

No intro, no logo, no "hey guys".
Put a bold caption on the hook line.
Before you cut, list the 3 strongest opening moments in my footage with timestamps so I can pick one.

Why these settings

  • People typically decide to stay or scroll in the first few seconds, so the hook gets its own instruction.
  • Saying what comes next (context, one sentence) keeps the video moving after a strong open.
  • An example of this kind of hook is "we killed pricing tiers yesterday, here's why".
  • Asking for options with timestamps lets you choose the opening yourself.

Fixes

  • Hook starts late. "Cut the breath and the half second before I start talking."
  • Wrong moment. "Use the clip at 2:14 as the hook instead."
  • The video drags after the hook. "Cut straight from the hook into context, one sentence, no pause."

FAQ

How long should the hook be on a founder build-in-public video? About 3 seconds, from the structure we use for this format. By then the video should already be into context, one sentence.

Can Vyra pick the hook for me? Yes. Ask for the strongest opening line. Ask for three options with timestamps if you want to choose.
