Now

Since February 2026, full-time. Using Claude Code, I design and direct a multi-agent AI system that researches a company's landing page or homepage and writes a long-form report on how well it converts, assessing positioning, messaging, the offer, persuasion, trust and proof, whether the copy speaks the customer's language, visual hierarchy, and more. I set its voice, structure, evidence rules, and quality bar. Pre-launch.

Founder, Writer, and Advisor

Created the Atomic Copy writing methodology, a complete system for clear, persuasive writing, taught to 47,900+ LinkedIn followers and 300+ paying customers through a writing guide and a landing page course. Grew that audience from zero in 12 months, five posts a week, and a weekly newsletter to 2,600+ subscribers at a 45% open rate. One landing page cheat sheet reached 1M+ views.

Wrote Napo's launch landing page and get-a-quote flow over four rounds of user testing, for a pet insurance startup that went on to raise a £15 million Series A.

Client work since 2021, in tech, finance, and consumer sectors, including Top Apps, Smarter Rent, Master Your Art, Red-on-line, Zero Down Lease, Bolt Energy Services, and Hire & Fire Your Kids: landing pages, website rewrites, onboarding flows, email sequences, ads, and brochures.

What colleagues say

Carolyn (Cal) Graham Chief Marketing Officer, Wayhome

As a new challenger brand in a complicated market it's imperative that our customers understand who we are and what we offer (and equally what we don't) in a clear and concise way. John nailed this and was passionate about making our proposition as clear as possible for our customers. His ability to understand the customer and produce copy that resonates with them and leads them to take the next step in their journey is second to none.

Arthur Boni Senior UX and Product Designer, Springer Nature Group

As a UX designer who was new to working with specialist content designers, I believe I could not have asked for someone better to work with. John produced a real shift in the way I think about words on a page, focusing on the reasons behind each piece of communication and ruthlessly getting rid of anything that didn't matter or that wasn't reader-centric.

Paulo Cunha Head of Product Strategy, Springer Nature Group

His deep knowledge of all things content coupled with a strong user-centric approach and curious mindset always looking for validation through data provided much needed focus … He was instrumental in delivering key initiatives to support the launch of one of our key products.

Nigel Purves Co-founder and CEO, Wayhome

John's natural affinity for and empathy with the user is his superpower. This allows him to write great copy, and craft great user experiences. He knows how to make the complex, simple; and the unknown, trustworthy. His copy is straightforward and clear, but also resonant and relatable.

Tim Hanson Co-founder, Penfriend.ai

John Harrison stands for clarity, clicks and conversion. The best copywriter I've ever had the pleasure of working with. Ever.
