Case Study: PhysicsWallah saves 90% of engineering bandwidth with Hevo Data

PhysicsWallah handles data at a massive scale and boosts customer satisfaction by 50% using Hevo Data

PhysicsWallah, an educational platform providing affordable online education in India, faced a significant challenge managing the massive data volume from its 1.5 million daily active users. The data team was struggling with over 600 tables and Python batch jobs, which caused high resource utilization and frequently made the application unresponsive. They needed a cost-effective and scalable solution to build a robust ELT system and turned to the vendor Hevo Data for its data integration platform.

Implementing Hevo Data's platform allowed PhysicsWallah to quickly set up and monitor pipelines at scale with features like hybrid schema mapping and pre-load transformations. The solution saved 90% of the time previously required, equating to the work of 3-4 data engineers, and enabled the processing of 1.5 billion events per month. This operational efficiency empowered over 500 analysts with data for critical reports, leading to a 50% improvement in the company's customer NPS score.
