Case Study: Mentimeter achieves reliable live event engagement at scale with Ably

Enriching live events with audience engagement at scale

Mentimeter, an audience engagement platform for live presentations, faced a significant challenge ensuring reliable realtime communication at massive scale. Their previous realtime infrastructure provider could not handle demand, suffering a crash during an event with 35,000 concurrent users and damaging customer confidence. They needed a new vendor that could guarantee performance, especially during instant spikes to 70,000+ participants, without requiring an in-house build.

Mentimeter implemented the Ably realtime messaging platform to power its live features. The solution was integrated within a month and provided the scalability and five-nines reliability they required. As a result, Ably seamlessly handles huge traffic spikes, has unlocked growth potential by allowing Mentimeter to raise its concurrent connection limit to 150,000, and has freed its engineers to focus on core product innovation instead of maintaining realtime infrastructure.
