# Heroku

Elixir supports internal financial services and data processing at the cloud application platform.

## How Heroku uses Elixir

Heroku’s Vault team adopted Elixir for internal licensing and financial services, including invoicing and payments. It started with a rewrite of a service whose requirements and risks were already understood.

The team then used GenStage to audit large amounts of data. A separate front-end team followed a similar adoption path, beginning with a well-understood problem before extending its use of the language.
