The best founder ghostwriting agency: what to check before you sign

Sell in Public → B2B LinkedIn content agency → founder ghostwriting → a founder voice buyers trust

Why choosing for a founder is different

A founder's LinkedIn profile does several jobs at once. Buyers read it to decide whether your company is worth a call. Candidates read it to decide whether to join. Investors read it, and so do your own employees. A generic agency that does fine work for a sales leader or a consultant can get a founder badly wrong, because the founder's voice is, for now, the company's voice.

Eight checks before you sign

1. Can they write like you, not like "a founder"?

Plenty of founder content sounds the same: a one-line hook, a story about a hard lesson, a list of five takeaways. Ask how the agency learns a voice. Good answers involve live conversations, listening to recordings of you talking to customers or your team, reading what you've written, and keeping notes on words you use and words you'd never use. Ask what they do when a draft doesn't sound like you. If the answer is "we'll tweak it," press for how they'll stop the same miss happening twice.

2. How much of your time will they need, in minutes?

Founder time is the scarcest input in the whole arrangement. A good agency gives you a specific weekly ask and sticks to it. Once things are running, about an hour a week is a reasonable ask to expect: a short conversation plus reviewing drafts. Be wary of two extremes: "just send us ideas whenever you have them" (which means you do the thinking in writing, on your own time) and "you won't need to do anything" (which means the posts won't contain anything only you know).

3. Do their clients look like you?

An agency that mostly writes for solo coaches will struggle with a technical B2B product and a long sales cycle. One that only works with large enterprises may bring a heavier process than a 30-person startup needs. Ask who their typical client is, what stage those companies are at and whether they've written for founders selling to buyers like yours.

4. How do they protect what you can't say yet?

Founders carry a lot of private information: a round that hasn't closed, a senior hire who hasn't resigned from their current job, a product launch, a big customer still in procurement, a pivot. A careless line ("big things coming, can't share yet!") can leak more than you meant. Ask:

• Will they sign an NDA as standard?
• Who sees your call recordings and notes, and where are they stored?
• What happens to that material when the engagement ends?
• Do any AI tools touch your recordings or drafts, and with what settings?
• How do they flag a draft that brushes against something sensitive?

5. Who actually writes the posts?

The person who pitches you is often not the person who writes for you. Ask to meet your writer before you sign. Ask how senior they are, how many other clients they write for and who covers when they're on holiday. If the honest answer is "an AI tool drafts and an editor polishes," you should know that up front.

6. Do you keep control of what goes out?

Nothing should publish under your name without your yes. Ask how approvals work, whether you see comment replies before they go out or agree on rules for them, and who has access to your LinkedIn account. A good agency will happily work with you pressing "post," or with a scheduler you control.

7. How easy is it to leave?

Check the minimum term, the notice period and what you keep when you go. You should walk away with your unpublished drafts, your topic notes and anything recorded from your interviews. Some agencies, such as Stop The Scroll, advertise month-to-month terms, so a long lock-in on a founder's first engagement deserves a good reason.

8. How will you both know it's working?

A founder doesn't need more impressions. You need the right buyers, candidates and partners noticing. Ask how the agency measures: tracked links, your CRM or sales data, and what people mention on first calls are all better signals than follower counts. An honest agency will also tell you what it can't measure.

What founders typically pay

Monthly fees vary mainly with how many posts you want, how deep the interviews go and whether engagement or other people are included. The published ranges disagree, and every one of them comes from a company that sells ghostwriting, so read them as rough bands:

Windmill Growth's guide puts most founders and executives at $2,000 to $5,000 a month, toward the low end of those bands.

Sell in Public doesn't publish prices; it quotes after a short intro call, based on how many people and posts are involved.

Red flags the checks won't always catch

• Promises of follower counts, viral posts or a number of inbound leads by a set date.
• Engagement pods, comment swaps or anything that pays for likes.
• A request for your LinkedIn password before anyone has talked about approvals.
• DM automation or connection campaigns bundled in under your name.
