VoilaNorbert is falling behind?
VoilaNorbert seems to be lacking many of the features that modern sales tools offer like outreach, phone number discovery, and many more. You can always use it for enrichment but BigPicture.io would be a better option in that case. When it comes to prospecting and outreach, VoilaNorbert is clearly not the best tool available. You are better off using a tool like Hunter.io or even a more modern tool like LeadLoft that features prospecting and outreach.
