BRINEL | IQANTO automates occupational medicine appointments at GFR with MARA, Romanian-language GenAI voice assistant

ABOUT THE CLIENT

Grup Feroviar Român (GFR) is the flagship company of Grampet Group, the largest private railway holding in the EU. With a fleet of 16.500 wagons and 2700 employees, GFR is one of the leading players in Romania's cargo rail transport market.

CLIENT CHALLENGE

Managers and HR staff contacted employees individually and followed up multiple times for confirmation. This process was time-consuming, error-prone, and risked non-compliance with labor regulations.

BRINEL | IQANTO, an AWS Advanced Tier Partner with Generative AI, Machine Learning, and Migration competencies, developed and implemented MARA - an autonomous voice assistant powered by Gen AI. Through this solution, GFR achieved:

  • 70%+ HR time reduction by eliminating manual tracking of medical appointments
  • 99%+ accuracy: automatically calls employees in Romanian
  • Real-time adaptive conversations based on employee responses
  • Automatic escalation to managers if appointments are not scheduled
  • Scales to thousands of employees simultaneously
  • 100% compliance with legal deadlines, GDPR, and enterprise security standards
  • Zero operational effort post-implementation — fully autonomous system

“MARA marks the beginning of a digital transformation in HR operations. With this intelligent tool, we've streamlined a key administrative workflow and experienced firsthand the benefits of AI in day-to-day work. The collaboration with BRINEL | IQANTO team was open and constructive. They understood the specifics of this project, adapted along the way, consistently searched for feedback, and responded promptly to our requests. We value the team's transparency, dedication, and commitment to our shared goals.”
