Lighthouse

Waitlist + survey + newsletter + feedback for indie founders. Validate your idea before you write code, capture survey answers on every waitlist signup, send the launch email when the list fills, then triage feedback after launch. On Pro, one click of AI analysis turns every answer into pain themes and audience segments, and an MCP server lets Claude, Cursor, or ChatGPT query your live waitlist in plain English. One toolkit instead of Mailchimp + Typeform + Canny + Carrd. 7-day free trial.
