Invite users in waves,
not all at once
Opening a beta to everyone on day one buries you in feedback you can't act on and support you can't keep up with. A waitlist gives every sign-up a position in the queue, so you can invite the first 50, fix what they find, then invite the next 200. Each wave is small enough to learn from and large enough to matter.
Segment sign-ups with survey questions — role, company size, use case — then export a cohort as CSV or pull it through the API to send invites from your own system.
Launch features
users actually want
A beta waitlist turns your roadmap guesses into measurable demand
before you commit development time.
Validate before building
Gauge real demand for a product or feature before committing development time. A waitlist is evidence, not a guess.
Organized beta testing
Recruit engaged testers from your queue and invite them in waves, so feedback arrives at a pace you can act on.
Data-driven roadmap
Prioritize what users sign up for, not what sounds good in planning. Sign-up and referral numbers rank your ideas for you.
Reduce customer churn
Give at-risk customers early access to what's coming next. A spot in the beta queue is a reason to stay.
Drive tier upgrades
Gate early access to premium features behind higher plans. Exclusivity gives users a concrete reason to upgrade.
Deep customer insights
Survey questions at sign-up capture role, company size, and use case — so you know exactly who wants what.
How to run a beta waitlist for your SaaS
From sign-up page to validated launch in four steps.
Create your sign-up page
Generate a page with the AI builder or start from the SaaS template — or embed the form on your marketing site.
Queue and segment sign-ups
Every subscriber gets a ranked position. Add survey questions to capture role, company size, or use case as they join.
Invite users in waves
Export a cohort or pull it through the API. Start small, fix what the first wave finds, then widen access.
Measure demand, then build
Sign-up rate, referrals, and survey answers tell you if the feature is worth building — before you write the code.

SaaS waitlist questions
Create a waitlist in Waitlister, then generate a sign-up page with the AI builder or start from the SaaS template — or embed the form on your existing marketing site. Add survey questions if you want to segment testers. Setup takes a few minutes and needs no code.
A beta waitlist is a ranked queue of people who signed up for early access to a product or feature before its public release. Instead of opening the beta to everyone at once, you invite people from the queue in controlled waves — which keeps feedback manageable and demand measurable.
Filter your subscribers by position, sign-up date, or survey answers, then export the segment as CSV or pull it through the API to grant access in your own system. Send that cohort an invite with an email broadcast, fix what they find, and repeat with the next wave.
Yes. Describe the feature on a sign-up page and share it with your users. The sign-up rate tells you how many people want it, referrals tell you how much they want it, and survey answers tell you why. See our guide on how to validate a product.
