Nest Bank rolls out Microsoft 365 Copilot to Polish staff, cutting workshop material prep time 90%

Overview

Nest Bank, a Polish bank focused on micro-entrepreneurs, migrated its data to Azure and Azure Databricks, first built an internal Azure OpenAI-powered admin assistant, then rolled out Microsoft 365 Copilot company-wide as one of the first companies in Europe to do so. Copilot cut the time to create workshop materials from an hour to five minutes (a 90% reduction) and is used to draft meeting agendas, summarize discussions and organize follow-up tasks, while the bank doubled sales and grew daily mobile transactions from 60,000 to 80,000 with the same headcount over 12 months.

The challenge

Nest Bank built an internal Azure OpenAI-powered assistant to automate administrative tasks, but employees were often not using it because it was not embedded into day-to-day processes, so staff continued doing manual work in PowerPoint, Word and Teams outside the tool.

The solution

Nest Bank revamped its data engineering by migrating data sources to Microsoft Azure and adopting Azure Databricks, then rolled out Microsoft 365 Copilot company-wide, embedding it directly into the Microsoft 365 applications employees already used for presentations, documents and meetings.

Reported business value

Creating workshop materials now takes five minutes instead of an hour, Copilot summarizes meeting discussions and organizes tasks after meetings, and helps staff overcome blank-page paralysis by generating first drafts; over the prior 12 months the bank doubled sales and grew daily mobile transactions from an average of 60,000 to 80,000 with the same headcount.
