Why creators give up on short-form
Short-form burns out the best creators.
Scripting, hooks, captions, vertical re-edits, hashtags — the editing tax kills the channel before it grows.
Pivot tax
Your YouTube audience and LinkedIn audience are different humans — writing twice is dead time.
First-line collapse
On LinkedIn, the first line decides everything. Most repurposing tools bury the punchline by line 4.
Format fatigue
Posting the same story 5 weeks in a row tanks reach. You need 5 different angles, not 5 copies.
Carousel-blocked
Carousels still hit hardest on LinkedIn — but designing them in Figma every week is unsustainable.
The PostSpark pipeline
From idea to ready-to-record in under 60 seconds.
Paste YouTube URL

First-line engineering
