Senior Copywriter
“I can say with absolute confidence that he's the only designer in Italy I trust to handle my clients' visuals. His ability to turn my ideas into powerful images and elevate my words is flawless.”
For founders, high-ticket publishers,
e-commerce brands and elite copywriters
You've already paid at least once for beautiful design that failed to make the phone ring.
I am Davide Filippini, the first Direct Response Designer in Italy.
Through Keryx Design I apply Readability Engineering to direct response marketing: I fuse sales psychology with data-driven CRO to eradicate the visual friction that quietly holds your copywriting back.
What clients say about the work
Senior Copywriter
“Davide not only delivered proposals that matched the level of my business, but also managed to skillfully combine design and strategy. In the two weeks leading up to the launch, I nearly reached break-even.”
Marketing Chief 3D4Steel
“We've been working with Davide for over a year now, and every piece of marketing material we produce goes through them. Davide's skills go far beyond design: he provides full-spectrum analysis including strategic and copywriting advice.”
Entrepreneur
“Having seen his previous work, I never had any doubt that he could create exactly what I was looking for. Davide managed to perfectly combine graphic design with strategy. Every visual element of the work could stand on its own and still make sense.”

keryx · the ambassador, from ancient Greek The manifesto
The creative method aims to please.
What you need is an ambassador.
In ancient Greece the Keryx was the official ambassador: he spoke with the king’s voice. He added nothing of his own, never performed, never chased applause. He delivered the message with the authority of the one who sent him.
And here is the problem.
The traditional creative method chases impact: abstract layouts, tiny type, heavy walls of text because they look “clean”. Those choices pull attention away from the message and lower conversions, however skilled the person applying them.
At Keryx Design, we act as ambassadors.
Your copy is the king’s message: I read its strategy first, dissect the psychological angles, and build a visual architecture completely submissive to the text. Because the most brilliant sales message is useless if your prospect’s eyes get tired after reading three lines.

Founder of Keryx Design
About & roots
Trained inside companies where every asset is measured.
My expertise does not come from pre-made templates, but from a certified historical path.
- I codified this discipline by publishing the first-ever thesis on Direct Response Design in Italy (Santa Giulia, 2019/2020).
- I spent 3 years as Chief Design Officer for Metodo Merenda, managing the creative department of the country’s leading direct marketing firm.
- I am the first Italian designer to complete Lori Haller’s advanced training, studying the exact visual frameworks used for Agora Inc.’s top controls.
- I mastered copy strategy directly inside Marco Lutzu’s elite internal team.
Today, I bridge the gap between classic direct-response legibility and modern digital CRO. I don’t sell pixels. I sell the visual engineering that allows your copy to convert.

CEO Dallan S.p.a.
“Making a direct marketing book both enjoyable and engaging is not always easy. In this case, the result is highly professional. Davide and his team have two key qualities: the ability to listen and great patience.”
Google Review
“I'll never change again. The ease and natural way they turn an idea into a flyer, a poster, a magazine is remarkable. And not just how good it looks, but the results in terms of bringing in new clients.”
Entrepreneur
“Davide is the most practical and cost-effective direct response marketer I know. He works fast, knows exactly what he's doing. If you have a startup or a small business, this is your guy.”
FAQ
The three questions I always get.
Do you use AI to design?
We use AI to accelerate technical production, but AI lacks the eyes to measure cognitive load. The scientific readability protocol is manually executed and supervised by Davide Filippini.
What happens if I want changes after delivery?
Every execution project includes 2 rounds of asynchronous revisions and a 30-day post-launch CRO monitoring phase. Future updates are quoted separately, on the same fixed-price logic: you know the number before work starts.
Do you offer custom hourly quotes?
No. We work on closed projects: the exact number comes out of the Feasibility Analysis, together with the delivery date. That eliminates long negotiations and ensures absolute transparency.
Apply
Apply for the Feasibility Analysis.
Keryx Design is a high-end boutique studio. We only work with companies that have strategic copy ready (or near completion) and want to protect their investment.
The gateway is the Feasibility Analysis, €147: a written plan plus a 30-minute live call. The plan is yours either way: if it shows the project would lose you money, we write that down and the work does not start. The fee is deducted in full from the project if it does.
