"AI Kubko has completely transformed VÚB Bank's approach to gathering internal feedback. The AI assistant engaged around 400 IT colleagues, who provided quick and honest answers to critical questions. Over 25% of them even said they would actively recommend AI Kubko to their colleagues as promoters. Thanks to built-in anonymization, it created a safe and open culture where employees could identify problems without self-censorship and even propose solutions."
