As a company based around adjusting their services to meet client expectations, KRUK optimise their effectiveness primarily to maintain a high standard of customer service.

The main goal of the chatbot and voicebot project was to support the customer service team and free it to devote more time to dealing with more complicated client requests. Additionally, the solution was meant to shorten the wait and servicing time, which has a direct impact on customer satisfaction. Implementing new technologies in KRUK is a crucial element in the further development of our services.

KRUK needed help primarily in:

  • Supporting the call center
  • Improving the call center’s efficiency after work hours
  • Improving service quality: shortening the wait and servicing times


SentiOne provided a custom voicebot and chatbot which handle client inquiries.

The SentiOne bots handled all incoming requests since its deployment. They have successfully handled 23% of them without the need to involve the customer service team. This provided KRUK’s call center with the required support. It improved request handling by shortening the total wait and servicing times. As a result, both the chatbot and the voicebot will be expanded to cover even more processes.
