Lighthouse

Lighthouse is a unified toolkit for indie SaaS founders to validate ideas and acquire early users. It combines waitlist signup forms, surveys, and newsletters, all with built-in AI insights on every response.

The product includes an MCP server integration that lets you query your waitlist directly from Claude, Cursor, or ChatGPT, bringing data analysis into your AI workflow. Replace multiple tools with one streamlined platform designed specifically for founders launching their first product.
