RevenueBase offers a complete B2B database service with unlimited prospect data and premium filters to drive revenue growth efficiently. RevenueBase is a B2B contact-data broker (~390M professional records) with no self-service opt-out form. Email privacy@revenuebase.ai with the subject line "Opt-Out Request" and include your full name, work email, and current or most recent employer; they say they will process within 30 days and add you to a suppression list so the data isn't re-added. Note that customers who already licensed your record may keep it, and California residents can alternatively use the CPPA's DROP platform.
