❓ Problem

Every founder has been told the same thing: post online. Your stories, your opinions, the scars from building the business, that is the stuff buyers want to read. And the data backs it up. In the 2024 Edelman-LinkedIn study, 73% of decision-makers said thought leadership is a more trustworthy way to judge a company than its marketing.

So why is LinkedIn's feed still a ghost town? The platform has 1.3 billion members, yet fewer than 3% post weekly. The problem is rarely a lack of ideas. It is that turning ideas into finished posts is the bit nobody can sustain. So founders do what founders do with any job they hate: they outsource it. Ghostwriters charge anywhere from $500 to $10,000 a month, with most buyers paying $2,000 to $5,000. The very best are billing $500 to $700 an hour, attorney money.

Here is the kicker. AI has made the writing part dramatically faster. Without it, five executive clients means 100+ hours a month of writing. With it, you can run ten clients in about 55. The bottleneck has moved. It is no longer the words, it is everything around them: call recordings in one folder, transcripts in another, drafts across six Google Docs, and feedback arriving on WhatsApp at 11pm saying "I'd never say that". Ghostwriters typically stall at three or four clients because voices blur together and approvals drag. And approvals really do drag: in Planable's own data, when sign-off is optional only 39% of posts get approved before they go live.

Dan Koe reckons one-person creative agencies are the big opportunity of the AI era. He is probably right. But nobody has built the operating system they run on.

✅ Solution

Ghostpost: the back office for a one-person content agency.

• Every client gets a workspace that remembers them. Past posts, interview transcripts, hot takes, pet phrases, banned words and examples of how they actually talk. A living voice profile that gets sharper with every edit and every "I'd never say that".
• One call in, a month of content out. Upload a client interview and Ghostpost pulls out the stories, opinions and lessons, then drafts a batch of LinkedIn posts, newsletter drafts and short video scripts, each tagged back to the moment in the call it came from.
• The agency owner stays in the driving seat. Everything is a draft until a human edits it. AI does the first 70%, the ghostwriter does the 30% that makes it sound like the client.
• A client portal with your name on it. Clients open a branded link, leave comments, approve or reject. No logins, no Google Doc version roulette, no screenshots on WhatsApp. Approved posts drop into a calendar and get scheduled.
• A pipeline view across every client. What is drafted, what is waiting on the client, what is scheduled, and who has gone quiet for nine days.

📊 Key Numbers

The agency economics

• Founder ghostwriting retainers mostly land at $2,000 to $5,000 a month, and funded SaaS companies spend the same range.
• At $2,000 per client, four clients is $8,000 a month. Get that same operator to ten clients and you are looking at a $240k-a-year one-person business.
• That is the whole pitch. A $2,000 client pays for the software for roughly a year. Help someone add one extra client and the subscription is a rounding error.
