TaskDrive supports sales and marketing teams by providing personalized lead research, data enrichment and account-based insights.
If you need a very high-touch list building service then this one's for you. You get assigned a researcher who allocates 40 hours/week just to you.
UpLead is a B2B prospecting platform that provides B2B contact & company data. Features include real-time email verification, contacts in over 200 countries, 50+ search criteria, technology tracking, account based marketing, competitor intelligence, email pattern intelligence, social profile links, Salesforce & 12 other CRM integrations, and a robust API.
We like the intuitive user interface, and it's also nice how they flag contacts that are potentially not up-to-date, so you don't waste your credits!
