Founders use FormSubmit to collect waitlist signups, demo requests and contact messages from landing pages — and pipe them into Slack, Sheets and their email tool.
The problem
A launch page needs to capture interest today, not after you've built a backend. And demo requests that sit unnoticed in an inbox are lost revenue.
How FormSubmit helps
Use the waitlist template or a demo-request form, post it to FormSubmit, and route submissions to a #leads Slack channel, a Google Sheet and Mailchimp or Kit at the same time. Signed webhooks let you create records in your own app when you're ready.
Works with your stack
Next.js, Astro, Framer, Webflow and AI-generated landing pages all work the same way — see the guides.
