About Lighthouse

Lighthouse is a toolkit for validating a product idea before building it. Its core is a waitlist landing page that can be created in under two minutes and carries survey questions on the signup form, so each email arrives with answers about what the person wants and would pay for. A QR code can be generated for posters or business cards, and Pro adds CSV export and a custom domain.

AI insights read every signup answer and return pain themes, audience segments and the phrases customers use, and an MCP server on Pro lets Claude, Cursor, ChatGPT or any MCP client query live waitlist, signup and feedback data. Standalone surveys support single choice, multiple choice, rating and free text in a multi-step mobile-first flow, and a newsletter and campaigns tool lets you import subscribers from a waitlist and send a launch email.

There is also a feedback board with full-text search and an API. The vendor presents it as one tool in place of separate waitlist, survey, newsletter and feedback subscriptions. Lighthouse is a hosted service where you can create a free waitlist with no account or card, and a 7-day preview.
