Making Gemini count across Ukraine’s largest bank, PrivatBank
Gemini was already part of PrivatBank's Google Workspace environment. The challenge was knowing where and how to use it to deliver real value.
PrivatBank is Ukraine's largest bank, serving around 18 million individual customers and 950,000 business customers, with 13.7 million people using its Privat24 platform. At that scale, putting Gemini to practical use meant giving teams across the bank the skills to make it relevant to their own work.
Within two days, about 300 employees had made that shift.
Getting to grips with Gemini
Getting there meant first understanding what was missing. Across the bank, employees had varying levels of familiarity with Gemini, ranging from what it could do to which use cases were relevant to their roles. They also lacked a common approach to crafting effective prompts.
The questions were practical: where could Gemini fit into people's working day, and how could employees across departments use the same technology for very different tasks?
Putting the bank's own work at the centre
PrivatBank and TeraSky Europe had already collaborated on Google Cloud initiatives for several years. For this project, TeraSky Europe was selected through a competitive public tender among Ukrainian and European Google Cloud partners. The existing relationship, TeraSky Europe’s experience, delivery capabilities, and close collaboration with Google were among the factors behind the decision.
TeraSky Europe’s certified trainers designed a two-day programme tailored to PrivatBank's business context and employees' needs across departments. This involved working with the types of tasks participants would encounter in their jobs, combining structured guidance with hands-on practice.
Participants explored Gemini across Google Workspace, including Gmail, Docs, Sheets and Drive, alongside the Gemini app and NotebookLM. They used it to summarise information, draft and refine content, and analyse data, while learning a structured approach to prompting.
By the end of the two days, the exercises had progressed from examples to practical takeaways for participants' own work. Each employee left with a working GemBot built for a real task.
Before and after
Before the programme, Gemini was already available through Google Workspace, but practical experience varied across teams. No one shared a prompting approach, and employees had different levels of understanding of where Gemini could fit into their day-to-day work.
After the training, around 300 employees learned a structured approach to prompting and tested it using real banking scenarios. Teams across the bank explored how Gemini could support role-specific tasks and workflows, and each participant left the programme with a working GemBot built for a real task.
For Vladyslav Klymenko, Technical Project Manager, Data & AI at PrivatBank, the two days marked a clear shift from exploring what AI might do to understanding how to work with it.
TeraSky Europe’s hands-on Gemini workshop turned our teams' curiosity about AI into practical, day-one skills. Over two intensive days, more than 300 employees across retail, business banking and operations learned to work with Gemini, Google Workspace and NotebookLM, and every participant left with their own working GemBot for a real task. TeraSky Europe’s Applied AI expertise and clear, practical delivery made this one of the most impactful enablement sessions we have run.
