Load Testing Becomes Crucial for Aircall After Landing Large Client

Compelling event

They first turned to load testing after the signature of a new large client who had one thousand users starting with Aircall and using the application at the same time.

At that time, Aircall was not able to handle this type of load, and it crashed.
They had several new potential clients that needed them to guarantee the load they were able to handle, and they had no framework or tool to do so, which led them to lose some signatures.

When they started using Gatling, they were pleasantly surprised by the support provided by the tech team, which helped them quickly improve their skills with the product.
Gatling Enterprise helped Aircall in many ways to acknowledge where their weaknesses were and to optimize their software, which led to new signatures with large clients.
