It' s the fourth Thursday in November. All Americans know exactly what's coming. The holiday season surrounding Thanksgiving is about to begin. And even though the most famous Friday can be traced back to the stock market crash in October 1929, Black Friday has become a global consumer event, both in-store and online.

Since 2013, Black Friday and Cyber Monday have also been common in German retail. So it is almost obligatory for every supplier to inspire (potential) customers with special offers and discounts for their products. But is it only the product and the discount in combination that matter in order to generate turnover? lexoffice, an accounting software provider, has a different view on this, and rightly so! Did you know that if a consumer is provided with a unique and uncomplicated shopping experience via digital channels, the purchase decision is far more positive? A much greater turnover can be generated through higher customer satisfaction.

Despite all the negative prejudices that have been published about chatbots in customer service, the decision was made to use a chatbot as an innovative communication technology. But what if the new communication technology is intended to win 1,000 new customers as well as encourage loyal lexoffice customers to win new ones? It's unthinkable with a classic question-answer (FAQ) chatbot. And last but not least, the chatbot's intents and tasks have to be developed and implemented within four short weeks? Unheard of in coding environments.


lexoffice as a client and provider, think moto as an implementation agency and Cognigy as software solution provider have jointly taken the risk: the development of the chatbot Lui. Lui is a tailor-made chatbot with an unprecedented user interface and a unique user experience. Lui is the central guide on the lexoffice website (, completely without menu navigation. The user interacts directly with Lui and receives all information up to the final purchase from Lui. Lui is intelligent in two ways. On one hand, by entering text in the chat (NLU), it can continuously learn to understand the customer's intentions (intents). On the other hand, Lui can differentiate new paying customers from existing paying customers who recommend the lexoffice product to others, so that it rounds off entire transactions via integrated backend systems, in this case Intercom.

How is Lui now after surviving Black Friday and Cyber Monday? Lui had 6,000 interactions on its first day, Black Friday, and was able to win 900 new customers for lexoffice on the Black Friday weekend alone. Miscommunication or even a bounce rate due to a lack of understanding by the user? Nothing. Because Lui guides the user intuitively through the dialogue so that the user receives all the desired information simply by interacting with Lui. Lui's logic, intelligence and transaction capabilities are built on the elementary features of Cognigy.AI - AI, automation and touch points. By using the Cognigy.AI low code editor, dialogues can be prepared fast and frictionlessly, allowing for advanced implementation in four weeks. Lui, which was actually only supposed to be used as a Black Friday campaign, is now an integral part of the website and has to date, generated over 2,000 sales for lexoffice. Lui is also continuously being expanded so that in the near future it will also be possible to hand it over directly to live agents/ consultants in order to pick up and convert potential customers even more successfully. Lui exceeds all expectations and shows that well-developed chatbots based on the conversational automation platform Cognigy.AI are, and will be, the core component of the e-commerce experience.
