You may regain access to a closed Pipedrive company by logging into Pipedrive with your existing details connected to the closed company and providing new billing information. Keep in mind that this is only possible as long as your data still exists on Pipedrive's servers.
Users without Admin User status cannot reactivate a closed Pipedrive account. If you'd like your account reactivated, please contact the Admin User of your company, Pipedrive account.
If you are having trouble regaining access to the account, you can contact support who will assist you.
