How the digital business card Höhle der Löwen convinces celebrities

Entrepreneurs all over the world dream of one day presenting themselves on the stage of the Lion's Den and possibly closing a deal with a lion. Digital business cards are in vogue and there is a shift from analog paper business cards to digital business cards in the form of a QR code.

There are a lot of providers of digital business cards on the market. One of them presented itself at the Höhle der Löwen. And another one is us from Lemontaps with over 8000 satisfied users.

The story behind My taag at the lion's den

In the 10th season of the Vox Gründershow one of the youngest founders Davis Zöllner (17) and Berkay Cankiran ( 18) almost still teenagers presented their start-up mytaag. On 4.10.2021, the show was broadcast on German television.

The founders replace the original paper business cards and offer the digital business card. Berkay Cankiran and Davis Zöllner use NFC technology for their stickers, which exchange contacts via smartphone with a tap. The stickers can be stuck on all cell phones and the contact data is customized in the mytaag app.

How long have lemontaps actually been around?

The Lemontaps brand has been around since April 2021, and the company's history began even before the 10th Höhle der Löwen season. Full of heart and conviction, Anna and Raji have been making business cards available digitally ever since, thus conserving precious resources. From the beginning, the goal was to connect people with each other in a fast and uncomplicated way.

The Corona pandemic had shown both founders how trade fairs and events were canceled, where people met each other beforehand and exchanged contact information as a matter of course, at that time still in the form of paper business cards. Raji and Anna thought it must be possible to connect with each other despite the pandemic. And so the success story took its course. See for yourself on the Wall of Love how enthusiastic customers are about Lemontaps.


Startup Lemontaps

Xeem a customer of us was also at the Höhle der Löwen

At this point we want to express our great joy about our customer Xeem, enthusiastic people who bring companies and employees together through challenges and enable collaboration. Xeem was also in the "Höhle der Löwen" and got a deal from the three lions Carsten Maschmeyer, Dagmar Wöhrl and guest lioness Sarna Röser for 300,000 euros for 25.1 percent.

When offline trade fairs are moved to the Internet

Many events, trade shows and conventions could no longer be held offline due to Corona. Companies have found solutions to offer online meetings and events where thousands of people can participate via the Internet.

Networking takes place online via QR code

Whether it's a smaller Zoom meeting or a large online convention you're speaking at. Add your Lemontaps QR code to your wallpaper and don't miss the opportunity to connect.

Imagine trying to physically give your business card to an audience of thousands. On the one hand, this would not necessarily be feasible in terms of time, and on the other hand, it would have cost you vast amounts of paper business cards.
