Write LinkedIn posts for busy founders in their own voice

Founders, coaches, consultants and executives who know they should post on LinkedIn pay you a monthly fee to write their posts. You interview them, draft the posts with ChatGPT so they sound like the client, and the client approves each one.

The hard part: making the posts sound enough like each client that they stop rewriting them, while finding new clients through one-to-one outreach.

Who pays

Clients pay a monthly fee for a set number of posts. AlexEngineerAI says $300 to $500 a month is a realistic starting price for 4 to 8 posts. The same poster says freelancers charge $500 to $1,500 a month for 3 to 5 posts a week. These are the poster's figures for what freelancers charge in general, not reported income from one business.

How to build it

  1. Find founders who post rarely

    Look for executives with 2,000+ LinkedIn followers who have not posted in 3+ months, or people who post only now and then. Comment on their posts for a week before you message them.

  2. Map each client's writing voice

    Paste 10 of the person's old posts or emails into ChatGPT. Ask it to describe their tone, word choices, and favorite topics, then save that description to reuse in every prompt.

  3. Send one free sample post

    Write one post in their voice and send it with a short message. This sample is your audition.

  4. Interview clients each month

    Hold a 20 to 30 minute call about their business, recent wins, and views on their industry. Record or transcribe the call so you have notes.

  5. Draft posts and get approval

    Give ChatGPT the call notes and the voice description to draft the month's posts. Share the drafts in a Google Doc so the client can approve them before you publish.

  6. Bill a monthly retainer

    Create a Stripe Payment Link for a monthly subscription for each package size.
