They found a voice for me on LinkedIn that actually sounds like me on a client call — not the version of me that tries too hard to sound impressive.

What we write
Six ways we build your voice.
We interview you first — every piece is built from how you actually talk about your work, not a generic LinkedIn template.
I
LinkedIn Ghostwriting
Weekly posts written in your voice, from a short call — so you show up consistently without writing a word yourself.
See packages
II
Thought Leadership Articles
Longer-form pieces for your blog or an industry publication, built around an argument only you could make.
III
Case Studies & White Papers
Researched, evidence-backed documents that turn your best client results into material your sales team can actually use.
IV
Website & Landing Page Copy
Homepage and service-page copy that reads like it was written by the person actually doing the work.
V
Email Newsletters
A regular newsletter that keeps your name in front of clients and referral partners between projects.
VI
Content Strategy & Editing
A standing plan for what to publish and when, plus editing for pieces you've already drafted yourself.

Every package includes research, drafting, and one round of polish before delivery. If your project sits between two tiers, tell us the scope — most projects are quoted around this ladder.

Our story
Written in Madrid, read by decision-makers.
Authoritywritinghub started when our founder — a former trade journalist — kept getting asked by client-side executives to help them write the LinkedIn posts they never had time for. What began as favors for a few contacts became a studio built entirely around one problem: smart people who are bad at making time to sound as sharp in writing as they do in person.
2020
First ghostwriting client
Began writing LinkedIn posts for a single Madrid-based consultant, based on monthly phone calls.
2022
First white paper
Expanded into longer-form research writing for clients pitching enterprise contracts.
2024
International clients
Began writing for executives outside Spain, still working entirely by phone and video call.
2026
600+ pieces published
A small team of former journalists and editors, still working client-by-client rather than at scale.

What it's like to work with us.
The white paper they wrote for us became our single most-requested piece of sales collateral within a month of publishing.
We started with a single case study and added the monthly LinkedIn package once we saw the response it got.
The interview-first process meant I barely had to write anything myself, and the posts still sounded exactly like me.
