Case Study: Bilt achieves scalable, secure authentication with FusionAuth

How Bilt Serves Millions on Google Cloud

Bilt, a fintech company operating a housing and neighborhood commerce network, faced significant challenges in scaling its authentication infrastructure to securely handle millions of users, particularly during cyclical traffic surges like rent due dates. Their non-negotiable technical needs included deploying to Google Cloud Engine, integrating with their CI/CD pipeline, and ensuring all data remained within their Google Cloud environment. Existing multi-tenant SaaS CIAM solutions lacked the required security, flexibility, and predictable pricing, creating a major roadblock.

FusionAuth provided the solution with its downloadable CIAM platform, which Bilt deployed into GCE-managed instance groups. This single-tenant architecture gave Bilt complete control over their data and versioning, seamlessly integrated with their CI/CD workflows, and ensured cost predictability without a usage-based tax. The results were a highly scalable system that handles millions of users and peak traffic surges effortlessly. FusionAuth enabled Bilt to maintain operational sovereignty, accelerate development cycles, and focus on building new features with the support of authentication experts.
