Case Study: Fey achieves 50x faster, 50x cheaper data processing with Inngest

Fey - Customer Case Study

Fey, a personal finance app, faced the challenge of quickly processing massive, complex financial datasets from multiple providers. Their existing tool, Google Cloud Composer, was inefficient, difficult to integrate with their JavaScript tech stack, and caused data updates to take up to a day. They needed a solution from a vendor like Inngest to orchestrate tasks and trigger reliable scheduled jobs.

By implementing Inngest’s SDK and leveraging its serverless functions, Fey significantly simplified its codebase and developer workflow. The results were dramatic: data processing became 50 times faster, with updates now near-instant, and monthly costs plummeted from $2,800 to under $100, providing massive efficiency gains and room to scale.
