Norbert is an intelligent lead generation tool that can find anyone's corporate email address and enrich it with data that drives conversion.
It won't blow you away but the accuracy is pretty good, and it has a clean user interface. It's one of the few platforms that doesn't require a subscription - you just pay for however many emails it finds.
LeadFuze uses third party data partners and in-house crawling to aggregate, match and verify real-time company info, emails, mobile numbers, social profiles and more.
They have a cool feature called FuzeBot, which can be set on autopilot and drip new contacts into your CRM as it finds them.
