Pik is currently in a limited beta release. We're working closely with selected Publishers to integrate Pik with their sites. If you'd like to discuss joining Pik as a publisher during this time, please let us know by sending an email to firstname.lastname@example.org and we'll get back to you promptly.
We will be opening up the ability for anyone to sign up as a publisher in 2018. If you'd like to be notified when this is ready, sign up to the newsletter on usepik.com.
