Reviews · verified
What those who are already moving the number say.
Verified reviews received on our Google Business profile. Unedited. If a review is harsh, it's published too.
With Cronuts Digital, our digital presence has been completely transformed. We now have a scalable B2B lead-generation system, continuous optimization, and content that reinforces our authority in the sector. This has not only improved our metrics, but also Eninter's perception as a technical leader in vertical mobility.
The mix of campaigns and content allowed us to grow visibility in the U.S. and, above all, capture qualified leads at sustainable costs in a complex B2B environment.
Our distributor was blown away by December's depletion results. The Paid Media campaign with cronuts.digital has helped us a lot with off-trade sell-out. While the gin category is falling -20%, The London Nº1 stays flat versus last year. On top of that, the major premium brands of our competitors are dropping.
Automation let us focus our energy on welcoming families while technology made sure each one received accurate information in their own language. Reaching a 43% lead-to-attendee conversion rate with zero manual handling has completely transformed our efficiency at the Open Days.
