LLM Training for a Banking Call Center

Our Challenge:

The client, one of the top 3 Banks in Eastern Europe, managed call center interactions. They aimed to train a neural network to autonomously categorize client requests (related to debit cards, credit, deposits or balance)

Our Solution:

Given the sensitive nature of the data containing personal information, strict adherence to non-disclosure agreements (NDAs) was paramount.

The client stipulated that only individuals under NDA could access the data. Moreover, they sought full visibility into work processes for quality control and operational oversight. Our in-house team of markup specialists executed the project.

Each specialist signed an NDA, ensuring confidentiality. Transparency was ensured through collective communication in group chats, weekly reports from mentors, and constant engagement with technical and legal teams


The data enabled the client to train a neural network achieving 96% accuracy in identifying bank deposit-related queries.

Post-project assessments indicated a 27% optimization in call center operations

"Modernizing systems through innovative technologies is a priority for us. Based on recommendations within the IT community, we engaged as contractors. Our call center now operates at peak efficiency. Thank you for this excellent collaboration!"
Head of IT department
