Waitlisted helps you build and vet your early adopters, while also amplifying your social reach by gamifying the signup process. Enable word of mouth by allowing users to improve their queue position by referring people. You can constantly re-engage users by allowing them to return to your site and check their position in line.
Next to this you can use Waitlisted’s simple export / management tools, or build your own interface with their JSON api. Waitlisted integrates with Slack, Mailchimp, Mailjet, Drip, WordPress and Zapier.
They are currently in private beta, but anyone coming from Startup Stash is able to register early!WAITLISTED.CO
