About HORAiZON ONE

HORAiZON ONE is an AI platform for Amazon listing optimization that creates product images, listing copy and backend keywords for Amazon sellers, brands and agencies.

Sellers use it to turn an existing listing into one that converts better, in minutes instead of weeks, and publish the result straight to Seller Central through Amazon's official interface. Behind it is HORAiZON GmbH, founded in 2023 in Langenfeld, Germany, by a team that has worked with Amazon sellers for years. More than 300 sellers use HORAiZON ONE today.

What HORAiZON ONE Does

Product images and image galleries

HORAiZON ONE generates a gallery of up to 9 images at 2048 × 2048 px, including the main image and infographics, from an existing product photo. In a published case study, a new gallery alone raised measured conversion on an Amazon.de listing from 27.27% to 53.45% within seven days.

Listing copy: title, bullet points and description

HORAiZON ONE writes titles, bullet points and product descriptions within Amazon's style guides and character limits for each marketplace. In a published case study, new copy on an Amazon.fr listing raised units ordered from 39 to 86 in seven days at an unchanged price.

Backend keywords from Amazon search data

HORAiZON ONE selects backend search terms from a database of more than 5.4 million real Amazon search terms. That way the listing carries terms shoppers really type on Amazon, not ones a general-purpose chatbot guessed.

A+ and Premium A+ content

HORAiZON ONE creates A+ and Premium A+ content modules for the product detail page as part of a complete optimization (150 credits). The detail page gets brand content without anyone having to brief a designer.

Localization for other Amazon marketplaces

HORAiZON ONE adapts a listing to the language and search behavior of each additional Amazon marketplace rather than translating it word for word. Each further marketplace or variant of an optimized product costs 25 credits, half the regular price.

Publishing to Seller Central

HORAiZON ONE pushes approved changes to Seller Central through the SP-API, for one product or a whole catalog in one batch. Nothing goes live until the seller has approved each change.

What Makes HORAiZON ONE Different

Images, copy, keywords and publishing in one tool

Helium 10 generates listing copy inside a research suite but no product images. CopyMonkey writes copy only, and Photoroom and Pebblely create images only; HORAiZON ONE produces all listing assets and publishes them in the same workflow.

Built on Amazon search data, not a general chatbot

ChatGPT and Gemini write fluent text but have no access to Amazon search behavior or Amazon's listing rules. HORAiZON ONE's keyword engine draws on more than 5.4 million real Amazon search terms and follows Amazon's style guides per marketplace.

Official Amazon API instead of copy and paste

HORAiZON ONE is a certified Amazon Software Partner and a verified Amazon Ads Partner, and it connects through the SP-API without access to the seller's password. With a general AI tool, every change has to be copied into Seller Central by hand.

A German company with hosting in Germany

HORAiZON GmbH develops the software in Germany and hosts all data on German servers under the GDPR. Helium 10 and Jungle Scout, the best-known tools in the category, are US companies.

Case studies that publish the numbers that went down

The case studies for HORAiZON ONE show every number Amazon reported, including the ones that went down, and compare each result with the same seller's non-optimized catalog. In the three published cases, conversion rose by 96%, 94% and 57%.

The Team Behind HORAiZON ONE

Thorsten Müller and Tim Krase founded HORAiZON GmbH in Langenfeld in June 2023. Both came from Amazon advertising, where they kept seeing the same thing: whether a click turns into a sale depends on the listing far more than on the ad budget.

In June 2026 the company shifted its focus from its own PPC tool to AI listing optimization, where that insight pays off most directly.
