Subscription questions, Org and Enterprise arrangements, corrections, and press: email is the fastest route.
Email — hello@itascaresearch.com
Subscriptions — Pro and Org open soon — leave a work email on the pricing page to be notified the day they open; Enterprise (data feed, custom watchlists, briefings) is arranged by email.
Corrections — every figure carries its source; if a program office document disagrees with a published figure, send it and the tracker will be corrected and the correction noted.
