Alex Lieberman, cofounder of Morning Brew, started StoryARB as a ghostwriting agency for B2B founders and executives who want to build an audience on X and LinkedIn. He saw agencies multiplying around short-form video while text-based executive media appeared less served. Before creating the service, he posted an offer inviting executives who lacked time or writing skill to DM him if they would spend $5,000 to $10,000 a year for help. He says 25 people responded. He then connected clients with two ghostwriters and coordinated the work in Slack, effectively testing demand before hiring a full team. At the time of the interview, he said the agency had 12 clients paying $7,000 per month each, or $84,000 in monthly top-line revenue and roughly $1 million annualized. The team included a CEO, a content strategist, and three freelance ghostwriters. Lieberman estimates the model's profit margin at 30–35%. These figures are founder-reported, not audited.
For an executive ghostwriting service at several thousand dollars per month, trust and specificity matter more than a broad agency website. Lieberman's first demand test was a direct social post: executives who believed in audience-building but lacked time or skill could DM if they would pay $5,000 to $10,000 a year.

“…so we have uh 12 clients uh that are paying $7,000 um a month so $84,000 Top Line a month it's roughly a million a year in annualized Revenue…”
9:16 · hear it in the videoData credibility: Alex Lieberman states on camera in a Starter Story interview that StoryARB has 12 clients paying $7,000 a month ($84,000 top line a month, roughly $1M annualized). The 30–35% margin is his estimate for 'this type of business', and the $10M / 110-client figure is a goal, not traction. No dashboard or accounts are shown. At the time he said the agency had not yet hit his own product-market-fit bar (50% of clients willing to recommend it, 10-month average retention).
StoryARB's first revenue came from matching demand to borrowed capacity rather than building an agency first. After the post generated 25 DMs, Lieberman connected clients with two ghostwriters and set up a Slack channel for each pairing so the writer worked directly with the executive.
The compounding loop for an executive ghostwriting agency is expertise capture, consistent publishing, and referrals from visible client outcomes. StoryARB interviews clients monthly, then its writers and content strategist turn the raw ideas into 12 pieces of content per week per client, according to Lieberman.
A new ghostwriting agency can go weeks without a clear signal: executives may like a draft but delay approval, and early posts may earn little visible engagement. Make progress observable through leading indicators under the agency's control.
StoryARB is a done-for-you executive content service, not a self-serve writing tool. The agency interviews a founder or executive, extracts useful ideas, and turns them into recurring posts for X and LinkedIn. Lieberman says the team creates 12 pieces per week per client and supports the process with two full-time employees and three freelance ghostwriters. A content strategist functions between account manager and editorial researcher, while the CEO handles agency leadership. Our read: the product is an editorial operating system wrapped around senior-level access. It needs a strong intake process, a reliable voice guide, factual review, and clear client approvals. The service is strongest when the executive has real expertise but lacks time to publish consistently. Avoid selling generic volume; the customer is paying for good judgment, a credible voice, and a repeatable production habit. The agency's value should be visible in the quality of ideas and the consistency of execution, not merely a count of posts.
At the time described, StoryARB had 12 clients paying $7,000 monthly, producing $84,000 in monthly top-line revenue and approximately $1 million in annualized revenue. Lieberman estimates 30–35% profit margins, implying the service must carefully manage labor and client load. He says the business has two full-time employees and three freelance writers. He also discusses a future scale target of 110 clients for a $10 million annual business; that is an ambition, not current traction. Our read: the core economic question is gross contribution per account after writing, strategy, revisions, and management. A monthly retainer aligns revenue with ongoing content production, but it also creates churn exposure if clients cannot see business value. A founder should define deliverables and revision limits, price for senior editorial work, and compare client lifetime to acquisition and onboarding cost. The 12-client count and fee are founder-reported and unaudited. Do not treat the projected $10 million target or stated margins as independently verified.
The operating stack described is intentionally light: clients are connected to ghostwriters, with Slack channels used to coordinate the work, and a monthly interview feeds 12 pieces of content per week per client. The service depends on people, editorial systems, and account management rather than proprietary software. Our read: standardize repeatable work in a client workspace with interview recordings, approved facts, voice notes, draft status, publishing schedule, and feedback history. Use secure storage and clear permissions because executives share sensitive plans. Measure writer hours, strategist hours, revision rounds, and late approvals for each account; these determine whether the 30–35% margin Lieberman cites for this kind of business is attainable as the client base grows. Keep a freelance bench for variable demand, but train writers and run quality checks so a client never hears an inconsistent voice. Software, salaries and contractor rates were not broken out, so a new agency should model them directly before assuming similar margins, and keep a reserve for months when an executive pauses.
Copy the demand-first launch: Lieberman described a specific buyer, a concrete recurring pain, and a willingness-to-pay range in a public post before creating the service. Then recruit enough delivery capacity to fulfill a few pilots and learn where quality control breaks. Change the model to match your own credibility and niche. A founder without a large audience may specialize in one executive category, such as technical founders or healthcare operators, and build proof through a small set of carefully approved case studies. Do not promise followers, leads, or virality that you cannot control. Our read: the defensible asset is the editorial process and trust between the client and the team; the writing itself is increasingly easy to commoditize. Build a method for capturing the client's real expertise, maintaining accuracy, and publishing on time. Expand only after renewals and referrals support the capacity plan. Use client recommendations and relationship length as health measures, not only the number of retainers sold.
This agency can fail through client churn, inconsistent writing quality, slow approvals, or founder dependence. Lieberman says retaining clients is harder than acquiring them and names 10 months as his average-duration goal for product-market fit; he had heard 3–5 months was common for ghostwriting agencies. A high monthly price makes customers sensitive to weak results, so the agency must connect publishing activity to meaningful conversations without claiming attribution it cannot prove. Scaling to many accounts can also dilute editorial quality and make the founder's brand less valuable to new CEOs or clients. Confidentiality and factual accuracy matter because ghostwritten executive content appears under another person's name. Our read: use written approval workflows, source notes, and a correction process, and avoid fabricating personal anecdotes or opinions. The reported revenue, margin, client count, and team details come from the founder interview and were not audited. Treat the $10 million target as a plan rather than a demonstrated outcome. A service that grows faster than its hiring and review systems can deliver may damage referrals faster than it adds revenue.
