01/The verdict

A done-for-you LinkedIn ghostwriting and personal branding agency for B2B founders, paid by founders at $650 to $3,999 a month.

Windmill is a well-run service agency with verified revenue of about $118k a month from roughly 75 active retainers. Nothing it sells is hard to reproduce: writers, strategists, AI drafting and LinkedIn outreach. Its founder has about 17K LinkedIn followers and 1.2K on X, so his reach is modest, and clients can leave each month without losing much, so a capable challenger can win customers within months.

Brand & trust

Shallow

~6 mo to cross

Windmill says it has served 185+ founders, publishes case studies and client testimonials, and appears in third-party roundups of the best LinkedIn ghostwriting agencies alongside Stop The Scroll and others. The founder has 17 months of verified revenue history and a 7-figure total.

To cross it: Sign 10 to 20 founders at a discount, publish their before-and-after LinkedIn growth as case studies, and get listed in the same comparison posts.

Founder brand

Shallow

~9 mo to cross

Ben Buaron has about 17K LinkedIn followers and 1.2K on X. He posts LinkedIn lessons and has appeared on podcasts like The Turning Pro about bootstrapping to 7 figures. That helps, but it is small next to the audiences top LinkedIn creators have built.

To cross it: Post daily on LinkedIn for 6 to 12 months and show your own account as proof the service works.

Distribution

Shallow

~6 mo to cross

Windmill runs a blog aimed at search, including its own 'best LinkedIn ghostwriting agencies' comparison page, and lists published pricing, but its domain rating is only about 27. Most new clients likely come through LinkedIn and referrals.

To cross it: Publish comparison and pricing pages for the same 'LinkedIn ghostwriting agency' keywords and buy into roundup lists.

Switching costs

Shallow

~2 mo to cross

Each client has a voice profile, a content backlog and a 'founder AI agent' trained on their posts, so switching agencies means a few weeks of onboarding again. The posts and the audience stay with the founder.

To cross it: Offer free onboarding that imports the client's past posts and builds a voice model in the first week.

03/The gap

Easy to copy

  • The AI drafting workflow and 'founder AI agent' trained on a client's past posts are a weekend build on top of Claude or GPT.
  • Profile optimization, ICP outreach campaigns and inbox management are standard agency services many freelancers already offer.
  • Published pricing of $650 and $3,999 a month makes it easy for rivals to undercut.
  • SaaS tools like Taplio and Supergrow let founders do much of this themselves for under $100 a month.

How you'd go after it

  • Go vertical: a ghostwriting agency only for fintech, healthtech or dev-tool founders, with writers who know the domain.
  • Sell outcomes, not posts: price on booked meetings or pipeline sourced from LinkedIn, which a retainer agency avoids.
  • Use your own LinkedIn account as the storefront: build a visible following and turn it into clients, the way the strongest agencies in this space do.
  • Bundle a cheap AI-assisted tier at $300 to $500 a month with a human editor, aimed at pre-seed founders who balk at $3,999.

04/Build against it?

Only with an edge

The market clearly pays, as Windmill's $1.27M over the last 12 months shows, but there are dozens of agencies and freelancers already selling this. Only enter with your own LinkedIn audience or a niche vertical you can own.
