Higher conversion rates with an advanced algorithm and intuitive interface
An area for improvement is the interface language, as our team mainly speaks French. Offering a French-language option would significantly enhance accessibility and streamline usage. Additionally, simplifying interactions with the Luigi's Box team, such as through localized support or tools tailored to non-English-speaking users, would improve collaboration. These changes would ensure a more seamless integration of the solution into our daily operations.

Robust solution with good value
Microsoft FAST is quite robust. Our clients are quite happy with it. For other users who already have a solution in place, we recommend Microsoft FAST because it is more compatible and you can organize the solution with Microsoft components. If you are with any other third party, there could be a chance that the required output is not what you would expect. But with Microsoft, it will work better. It is compatible with the older generation systems, so you can offer it. On a scale of one to ten, I would give Microsoft FAST an eight because I'm quite comfortable with it.
