Your best marketing happened on someone else's feed
You spent an hour sharing expertise on a show with an audience you want. Then you posted nothing - or a single 'listen to my episode' link that died in the algorithm. Your authority stayed on their platform.

Guest spots do not build your brandThe host's audience heard you once. Your LinkedIn network never got the frameworks, stories, or hot takes you delivered.
You will not write it up yourselfYou are not going to listen back and draft five posts. You are onto the next meeting. The content dies in Apple Podcasts.
Ghostwriters miss how you actually talkA writer who was not in the room cannot capture the phrasing that made the host say 'that is going on the show notes.'
I started with a podcast.Then the invitations started coming.
I built SparkVox to turn my own podcast recordings into LinkedIn posts. That was five months ago. Since then I have had 10+ podcast invitations, and the same workflow now also produces the posts that promote SparkVox.
