The best SaaS launches don't start on launch day — they start months earlier with a waitlist. Build demand, validate your idea, and create urgency with Waitloop.
You've spent months building. On launch day, you post to Twitter and... crickets.
Launching to no audience means zero signups on day one. No social proof. No momentum.
Without a waitlist, you're guessing if anyone actually wants what you're building.
People see your demo on Twitter, love it, but have nowhere to sign up. Interest evaporates.
Three lines of HTML. That's all it takes to turn your landing page into a lead-capturing machine.
Add a simple HTML form with your Waitloop URL as the action. Collect email, name, company — whatever fields matter to you.
<form action="https://api.waitloop.io/f/YOUR_KEY" method="POST"> <input name="email" placeholder="you@startup.io" /> <input name="company" placeholder="Company name" /> <button type="submit">Request Early Access</button> </form>
Every submission appears in your Waitloop dashboard in real-time. See position numbers, referral sources, and UTM campaign data automatically.
Each signup gets a unique referral link. When someone they share with signs up, they move up the queue. Built-in viral growth loop.
Every feature designed to maximize your pre-launch momentum.
Signups see their position number. "You're #47 in line" creates urgency and encourages sharing to move up.
Works with React, Vue, Webflow, Carrd, plain HTML, or any AI-generated landing page. Just change the form action URL.
Automatically captures UTM parameters and referrer data. See which Twitter post, Product Hunt listing, or blog drove the most signups.
When it's go time, export your entire waitlist with one click. Import into your email tool and send your launch announcement.
A solo founder building an AI project management tool created a landing page with Cursor in 20 minutes. Added a Waitloop form in 30 seconds.
Posted a demo video on Twitter. The tweet went semi-viral — 50K views. Interested people clicked through and joined the waitlist.
Referral links kicked in — early signups shared with their teams. The waitlist grew from 200 to 1,400 in a week without any additional marketing.
On launch day, they exported the CSV and sent 1,400 personalized invite emails. 38% converted to paying users in the first week.
