# Startup apps you can build with a coding agent

> Apps for early-stage teams, starting with a launch waitlist that collects signups and rewards referrals. Each example has a live demo and a prompt your coding agent can build from.

Early-stage teams need working tools before they need an engineering team: a waitlist to collect interest, a simple CRM to track conversations, a place to gather feedback. Each example is a live Userland app with the prompt that builds it.

## Examples

- [Waitlist App](https://userland.fun/examples/waitlist-app/index.md): Pre-launch waitlist with invite links that move people up the line, optional questions, and an owner view with a spreadsheet download.
