LighthouseValidate your idea
before you write code.
Get your first 100 users.
And keep them growing.
Lighthouse is a waitlist, survey, newsletter, and feedback toolkit for indie founders, makers, and indie iOS developers. Validate your idea with a waitlist that attaches survey questions to every signup, keep early users engaged through a built-in newsletter, collect product feedback after launch, and wire any of it into your own app through a REST API. Free tier available, then $19/month for unlimited core features, or $29/month with the API and custom domains.
Three steps to a validated launch.
From “I have an idea” to “I have evidence” in a single afternoon. No code, no integrations, no separate tools.
Create your waitlist
Spin up a signup page in two minutes. Attach survey questions or a free-text field so every signup teaches you something.
Share it everywhere
Drop the link on social. Print the QR code on a business card. Show it at your booth. Every channel funnels into one place.
Read the data, then launch
Watch your signup counter climb. Read survey responses to decide what to build first. Send the launch email when you're ready.
Three steps to keep and grow.
You launched. Now turn signups into engaged users. The same toolkit follows you from day one to day one thousand.
Onboard with surveys
Greet new users with a short survey. Learn their role, what they need, and how they found you. Segment and personalize from day one.
Stay in touch with newsletters
Import your waitlist as subscribers. Send updates, share features, keep users in the loop. One tool, no extra Mailchimp.
Listen with feedback
Collect bugs, feature requests, and praise from real users. Rate, categorize, decide what to build next.
One toolkit instead of five subscriptions.
Waitlists, surveys, newsletters, feedback, and an API, built to work together. Stop duct-taping Mailchimp, Typeform, Canny, and a spreadsheet.

How is this different from a Mailchimp waitlist?
A normal waitlist gives you an email count. Lighthouse gives you an email count plus the survey data that tells you why people signed up, what they want most, and what they'd pay. You're validating, not just collecting.
Do I need any technical skills?
No. Starter is fully no-code. You create a waitlist, share the link or QR, and read responses in your dashboard. Pro adds API access for founders who want to wire Lighthouse into their own product.
Can I see individual emails?
On Starter you see signup counts, analytics, and can export CSV data. Pro unlocks individual email addresses in the dashboard and API, plus CSV export with full email lists.
What if I outgrow the plan?
Upgrade or downgrade from your dashboard, prorated automatically. We don't lock data behind tiers. Your historical responses stay yours on any plan.
Can I bring my own domain?
Yes, on Pro. Run your waitlist on join.yourproduct.com instead of lighthouse.build/runwell. Free SSL, two-minute DNS setup.
Your next idea deserves evidence, not faith.
Build your waitlist, attach a question or two, share the link, and watch real people tell you what to build.
