An unlimited number of people can view and submit your signup form. Your subscription determines the number of users you can see.
We generate a unique share link and encourage your users to refer friends through email and social media, such as on Facebook, Twitter, LinkedIn and more.
Send personalized emails based on what your users do. For example, send a thank you email immediately after someone signs up, or reward them for referring friends.
Prevent people from using disposable email addresses or from signing up multiple times from the same IP address.
Use custom CSS to make the form match your brand. Your users won't even know that Prefinery is part of your project.
Invite everyone on your team to view and invite your users!
We automagically turn the email address of your users into a rich social profile including name, social networks, company, title, age, gender and location.
Already have a list of people you want to invite? No problem. You can easily import a CSV file of existing users into Prefinery.
Your data is yours. You can easily export all users to a CSV file, which can be opened in your favorite spreadsheet application.
Your users will continue to be able to sign up — no user will ever be turned away! While an unlimited number of users can submit your signup form, if you go over your limit you won't be able to see those additional users until you upgrade your subscription.
We provide something even better than a limited time trial — a forever free account! You can sign up for a free account and take Prefinery for a test drive to ensure that it will meet your needs.
Just get in touch and we'll build you a custom plan with up to 1M users.
We accept Visa, MasterCard, American Express, Discover, JCB, and Diners Club cards.
Of course. You can do this from within your Prefinery account.
We want to treat you right. If you’re not satisfied for one reason or another, get in touch with us!
No way. Prefinery is a pay-as-you-go service. There are no long term contracts or commitments on your part. You simply pay month-to-month. If you cancel, you'll be billed for the current month, but you won't be billed again.
We are hosted on a cluster of servers with Amazon Web Services for reliability and speed. All of your data is replicated in realtime to redundant databases and fully backed up every night. Our uptime is over 99.99%.
