How Ouinext Accelerated Its Expansion in the Polish Market Using Milega’s H-AI-Brid Translation Method

In an increasingly globalised cryptocurrency market, the ability to communicate with users in their native language represents a considerable competitive advantage. This is the challenge that Ouinext, an innovative platform in the cryptocurrency sector, undertook by leveraging our expertise to translate its entire platform and technical documentation into Polish.

This case study outlines how our unique approach, the H-AI-Brid method, enabled Ouinext to achieve substantial savings while significantly accelerating its expansion into the Polish market.

The client: Ouinext

Ouinext is a cryptocurrency-focused company founded by Christophe Le Chevallier. In a highly competitive sector, Ouinext stands out for its commitment to providing accessible and understandable services for all users, regardless of their language.

Recognising the opportunity represented by the increasingly cryptocurrency-interested Polish market, Ouinext sought to offer a fully localised user experience for this audience.

The challenge: A large volume of technical content to translate quickly

The project faced several major challenges:

  • Significant volume
    The project comprised a total of nearly 70,000 words, distributed as follows:
    • Trading platform interface: 5,388 words
    • SEO FAQ: 1,392 words
    • Cryptocurrency technical glossary: 61,000 words
  • Technical complexity
    The cryptocurrency sector uses very specific terminology that requires an in-depth understanding of the field. A simple translation mistake can lead to significant confusion for users, and even potential regulatory compliance issues.
  • Budget constraints
    Like any growing business, Ouinext needed to optimise its investments. A fully human traditional translation would have been prohibitively expensive, particularly for the 61,000-word technical glossary.
  • Tight deadlines
    To seize the opportunity in the Polish market ahead of the competition, Ouinext required a quick solution without compromising on quality.

Our solution: The H-AI-Brid method in 3 steps

In the face of these challenges, we proposed our H-AI-Brid method, a three-step sequential approach that intelligently combines human expertise with artificial intelligence technologies:

Step 1: Direct translation of strategic content by expert human translators

The most critical elements of the user interface and sections with high commercial impact were entrusted directly to our expert translators who specialise in finance and cryptocurrency. These native Polish translators possess dual expertise: linguistic and technical.
This first step ensured impeccable quality for the most visible and strategic content of the platform.

Step 2: Creation and application of a specific glossary

Our linguists identified and translated 250 key terms from the cryptocurrency sector to create a specific glossary. This glossary served as a reference for the entire project, ensuring perfect terminological consistency throughout the platform.
Among these terms were technical concepts such as blockchain, cold wallet, mining, smart contract, as well as terms specific to Ouinext’s interface and its particular features.

Step 3: Use of AI optimised for the remaining content

For the 61,000-word technical glossary, we employed our machine translation technology enriched with the specific glossary and optimised by advanced language models (LLM) and Retrieval-Augmented Generation (RAG) technology.
This approach yielded translations of quality 60% superior to standard machine translation solutions like DeepL or ChatGPT. Each translated segment then underwent targeted human revision to ensure the final quality.

Results: Substantial savings and significant time gains

Significant financial savings

  • 62% savings compared to a fully human traditional translation using the H-AI-Brid method with revision.
  • Potential savings of up to 79% with the H-AI-Brid method without revision (for less critical content).

In concrete terms, the necessary budget dropped from over €10,000 to about €3,800, allowing Ouinext to reallocate these resources to other aspects of its international development.

Drastic reduction in timelines

  • Reduction of deadlines by 67%: from 6 weeks to just 2 weeks.
  • Accelerated launch enabling Ouinext to gain a competitive advantage in the Polish market.

This speed of execution was particularly appreciated by Ouinext, which was able to launch its platform in Polish well ahead of the initially planned date.

Superior quality

  • Translations of a quality 60% superior to standard machine translation solutions.
  • Perfect terminological consistency achieved through the specific glossary.
  • Appropriate cultural adaptation for the Polish market.

Client testimonial

“The H-AI-Brid method proposed by the agency allowed us to achieve substantial savings while maintaining exceptional translation quality. The relevance of the translations in our cryptocurrency business context was remarkable.

Impact on Ouinext’s development

Acceleration of market penetration in Poland

Thanks to a fully translated and culturally adapted interface, Ouinext was able to quickly attract Polish users to its platform. The quality of the translation contributed to establishing the company’s credibility in this new market.

Improvement of user experience

Polish users navigated through an interface perfectly tailored to their language, with consistent and precise terminology. This optimal user experience helped reduce the bounce rate and increase the conversion rate.

Competitive advantage

By being among the first cryptocurrency platforms to offer a fully localised experience in Polish, Ouinext was able to stand out from the competition and establish its presence in this market ahead of other players.

Why this approach worked

The success of this project rests on several key factors:

  • A methodology suited to volume
    The H-AI-Brid method is particularly effective for projects involving a large volume of technical content, as was the case for Ouinext with its 70,000 words to translate.
  • An optimised sequential approach
    By first addressing the strategic content with human translators, then creating a specific glossary before using AI, we maximised quality while optimising costs.
  • Sector expertise
    Our in-depth knowledge of the cryptocurrency sector allowed us to understand Ouinext’s specific challenges and adapt our approach accordingly.
  • Advanced AI technology
    Our machine translation technology, enriched by the specific glossary and optimised by advanced language models, yielded significantly superior results compared to standard solutions.

Conclusion

The Ouinext case perfectly illustrates how the H-AI-Brid method can transform a complex translation challenge into an opportunity for international development. By intelligently combining human expertise with AI technologies, we enabled Ouinext to achieve substantial savings, significantly reduce its time to market, while maintaining exceptional translation quality.

This sequential approach (human → glossary → AI) is particularly suited for high-volume translation projects in technical sectors like cryptocurrencies.
