The most important feature of Julius was that it makes content discovery extremely easy.
It also has some really smart features around building custom tags (which are very intuitive). I wish there were more integrations available between Julius and our CRM / Marketing automation platforms - this would have saved us so much time! We previously had issues finding high quality influencers who could help promote our products. With the launch of Julius we saw an immediate increase in new contacts from people we didn't know before.
