Who invented it?
We were selling more and more Cooling Cubes, and we had to improve our processes and logistics. We were slowly reaching the limit of what we could deliver. We had been thinking in terms of hundreds of Cooling Cubes, but we were now working with thousands.
We have had loads of great photos from happy Cooling Cubes customers via social media, email and WhatsApp. Thank you very much! And please send us more!
Our first big festival. Amazing! Our Cooling Cubes stand was right in the middle of the action. Lots of work, lots of people, lots of fun, lots of sun and lots of ice-cold beer. Have a look for yourself.
Looks like we made it. We’ve been featured on the Playboy website. This is a website that shows everything that men like.To the video.
Put your cold beer in your Cooling Cubes, spend all day on the beach, and your beer will still be cold in the evening. How can we get this message across? With a video! We flew to Tenerife to see Marius Hoppe and made a cute little film with his friend Tessa Kudrass.
Cooling Cubes won the 2017 promotional gift award and we went up on stage in Bonn to receive it. Cooling Cubes have a wonderful texture and feel, and are a great corporate gift. Check out our deals for companies.
Our garage was now too small. We managed to find room in an old factory. A really cool location with loads of character and plenty of space.
Next stop was the Startup Con in Cologne. A company making actual things got plenty of attention next to all the digital start-ups. Our brightly coloured cubes also caught the attention of the television cameras.
We stored the first delivery from our producer, GWK Kuhlmann, in Ingo’s garage. And then we started sending out package after package. A proper garage start-up. Just like Apple.
But after the fun, it was time to go back to work. We sent thank-you presents to all of our supporters. But our offices were full of Cooling Cubes, cooling blocks and more.
This certainly called for a celebration. And what better way to celebrate the birth of Cooling Cubes, than with a big party. We invited all of our crowdfunding supporters. And we made sure they had plenty to drink - without bar or barkeeper. There was plenty of ice-cold beer, cocktails and white wine for everyone. Have a look at our after-party video.
The first day of production. The very first Cooling Cubes. Not everything was perfect, but it was pretty good. And we will never forget the moment the first Cooling Cubes came out of the mould.
While we were waiting for the money to come in, we had to take some decisions. What colour would people want their Cooling Cubes to be? We decided to offer pretty much everything, and see what sold best.
Meanwhile the costs of the project had gone way beyond what we expected. As well as special machines, we had lawyers’ fees, packaging, instructions, marketing, an online shop and more. So we decided to try crowdfunding. And we were amazed to attract €21,000 with this cool video. Check out our Startnext crowdfunding profile, too.
Within one year of having the idea, special machines we needed to make the precise shape we wanted were already being built. We had learned a lot about moulding, and hoped that there would be no problems with larger production runs. It’s rare that nothing goes wrong, but we were either very good or very lucky.
The tests with the first prototype showed that the beer really did stay cold, and pouring was easy. But the tap dripped onto the bottom of the Cooling Cubes, and that didn’t look great. So we adapted the shape and tried again.
We also needed a logo and an idea for the brand name. Maybe we had been watching too many YouTube videos from California. But we agreed pretty quickly, that this was the kind of feeling we wanted to express. Cooling Cubes mean freedom, fun, beaches and ice-cold beer.
Our first professionally made Cooling Cubes prototype arrived. An amazing moment after months of hard work. Definitely worth raising a glass – or five! The beer stayed cold right to the last drop. Fantastic! But we did have to carry on testing for a few months, just to be sure.
The round keg needed to be put into the square cubes. But how? A cooling block at the top of the keg would stop warm air from getting in. And then we wanted to have the tap at a height to allow beer to be poured comfortably - from a table or when lying on the beach. A bit of storage space would be useful. And if the whole thing could be used as a stool, even better. We had a pretty long wish-list.
The first sketches identified two cubes as an elegant solution. The hole on top of the upper cube was already sketched in. But we were still a long way from the finished product.
Our first try was made with polyurethane foam from a DIY shop. We tried to work out how to make insulation that would fit the keg perfectly. Our early attempts weren’t very impressive, but we got better step-by-step.
Our mission: To find the best way of keeping 5 litre beer kegs really cold for a really long time. Our solution should look good and be easy to carry around.
No more warm beer! We want ice cold draught beer - right to the last drop. Even if we are miles from the nearest fridge. Or just too lazy to go from the sofa to the kitchen.
