Case Study: Testim scales reliably and gains enterprise-grade performance and data control with MongoDB

Testim - Customer Case Study

Testim, a startup building a SaaS product, relied on Google Firebase for three years because it was quick to adopt, offered real-time sync, built‑in auth and simple hosting. As the product and customer data grew, Firebase’s limits — messy client-side coupling, limited querying, no easy local or staging environments, painful large-data exports, poor observability and slow support — began causing performance issues, outages and operational bottlenecks.

Over a three-month migration Testim moved to MongoDB (using MongoDB Atlas for some customers), a smooth transition that enabled complex queries, local and on‑prem deployments, robust backups and monitoring, and lower costs. The switch restored platform portability, improved scalability and development velocity, and met enterprise requirements for control and observability.
