In Depth
What you are actually choosing between
A PR agency and a LinkedIn ghostwriting agency are solving different problems, and buyers who conflate them tend to overpay for the wrong one. A PR agency earns you third-party coverage: a byline in a trade title, a mention in a funding round-up, a quote in a journalist's piece. The authority is borrowed from the outlet. A LinkedIn ghostwriting agency builds authority that lives on your own profile, in your own voice, in front of the exact people you want to reach - buyers, partners, hiring targets, and increasingly the journalists who now source stories from LinkedIn.
The confusion is understandable because both promise "visibility". The difference is who controls the channel and who owns the relationship. Coverage in a publication expires the week it runs and lives on a domain you do not own. A body of writing on your own profile compounds: someone who lands on your page in month nine reads eight months of thinking, not a single dated headline.
For a B2B founder pre-Series A, or a fractional executive between mandates, that distinction decides where the next conversation comes from. PR gets you seen by a broad, mostly passive audience. LinkedIn ghostwriting gets you known by a narrow, specific one that is already deciding who to trust.
Where each one actually wins
PR is the right tool when the objective is credibility signalling to a wide market fast: a launch, a raise, a category you need journalists to validate. A logo bar of "as featured in" still moves cold buyers, and a strong PR firm can place you in three to five relevant titles over a quarter. What it rarely does is generate inbound. A quote in a trade weekly does not put your calendar link in front of a buyer at the moment they feel the pain you solve.
LinkedIn ghostwriting wins on depth and repeatability. A founder posting two to three times a week for six months builds a searchable, scrollable record of how they think about their market. That is what warms a buyer before the first call, and it is why a well-run programme changes the temperature of your inbound: fewer cold pitches, more people arriving already sold on the specific way you see the problem. The trade-off is patience. PR can spike in a week; authority on LinkedIn builds over months, then holds.
Cost tells the same story. A retained PR firm typically runs 5,000 to 15,000 pounds a month with placement, not pipeline, as the deliverable. A serious ghostwriting programme sits lower and ties directly to your voice and your buyers. If you need a headline this month, PR. If you need to be the name that comes up when your niche is deciding who to trust, ghostwriting.
Where most buyers get it wrong
The common mistake is treating the two as interchangeable line items and picking on price. PR bought as a substitute for owned authority leaves you with clippings nobody in your buying market ever reads, whilst ghostwriting bought as a substitute for a launch strategy leaves a good story unamplified. They do different jobs, and the strongest founders run them in sequence: build the owned voice first, then use PR to amplify the point of view you have already made credible.
The second error is outsourcing your thinking. A PR firm writes about you; the best ghostwriting does the opposite, capturing how you actually reason so the writing reads as unmistakably yours. That is the line most agencies blur, and it is the one that decides whether readers believe a human is behind the profile.
How Underdog runs it
We start with Voice Capture, a 90-minute session that records how you think, argue and phrase things under real questions, so every post carries your judgement rather than a writer's guess. Then Social Scout maps who is already engaging in your space - the buyers, operators and adjacent voices whose attention compounds - so we write toward the people who move your market rather than a vanity audience.
AI accelerates the drafting and the pattern-spotting; the insight and the voice stay yours throughout. The result is a body of owned authority that keeps working long after any single placement fades, built for the buyers who decide who to trust. When a PR moment comes, you amplify from a position of established credibility rather than starting cold. See our [LinkedIn ghostwriting service](/services/linkedin-ghostwriting), the [founder authority guide](/guides/founder-authority-linkedin), and [client results](/case-studies) for how this plays out in practice.
