Leadspace CDP gives B2B Sales & Marketing the ability to focus on growing revenue faster personalized engagement, instead of spending time managing data. Leadspace is a self-described California data broker that sells B2B ('Business Personal Information') profiles. To opt out of the sale/sharing of your data, use the 'Do Not Sell My Personal Information' page linked from the privacy policy and site footer (exact URL is not printed in the policy text, so verify the link from the footer). Access, correction, and deletion requests must be emailed to Compliance_privacy@leadspace.com. They verify identity before acting — roughly 5,300 of 25,000 requests in 2025 were denied for insufficient identifying information, so include full name, business email, employer, and job title. Stated response target is 45 days (extendable by 45); mailing-list opt-outs take up to 10 business days.
