The problem
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 brand
The 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 yourself
You 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 talk
A writer who was not in the room cannot capture the phrasing that made the host say 'that is going on the show notes.'
The solution
Your guest appearance becomes two weeks of content.
Upload the episode and choose Guest perspective - Sparky diarizes the recording, has you pick your voice from sample speaker lines, then drafts posts from only your moments, grouped by funnel stage: Awareness, Authority, and Conversion. Review in your project and approve while the conversation is still timely.

Why it works
Built for how expert guests actually work
Ride the publicity window
An episode's reach peaks in the first 72 hours - post while it's new, tag the host, and stack impressions on both audiences before that window closes.
Your voice only - not the host's
Speaker diarization separates your track from the host's before any post is drafted, so posts come from what you said, not from questions you were asked.
Funnel-aware content from one appearance
One episode typically contains Awareness moments, Authority moments, and Conversion moments - Sparky groups drafts by stage so one guest spot builds reach, trust, and inbound, not five posts doing the same job.
Sparky Brief - your story already loaded before the transcript arrives
Brief Sparky once on who you are and your audience, and every guest appearance drafts with that context already loaded - so posts connect your ideas to your story, not just the episode topic.
Guardrails
Built for guests who want more than a link post.
Your words from the episode. Review in minutes. Nothing publishes without approval.
Your track only
Speaker selection keeps the host's questions and banter out of your drafts.
Review while it's fresh
Approve drafts in about 10 minutes, while the episode is still in the feed.
Nothing ships unapproved
Every post stays in your project for review before it reaches LinkedIn.
From the founder
"The best founders I know guest on three podcasts a month and post zero times about it. That is leaving pipeline on the table."
