What it is

Build and run complex workflows that run in the background.

Real use case example

"A founder wants to automate a welcome process for new customers signing up on Stripe. They use Cadence to build a workflow that adds a new customer to Notion, sends a welcome email via Mailgun, and updates their customer profile. When a new customer signs up, the workflow executes in the background."
