What they told YC

What is your company going to make? Please describe your product and what it does or will do.
The founders are building Defer to make it easier for developers to add background operations to web applications, such as calling third-party APIs, sending notifications, and exporting data. They note that these features typically require infrastructure work early on and become difficult to scale later, and they aim to make deploying such functionality comparable to deploying a Vercel application.
