Sandy's story

May 2016...and the world suddenly turns upside down.

At least that's how it was for Marc and his family when they received the shock diagnosis. Their son Dexter had been diagnosed with cancer - and he was only two years old! The doctors could not possibly operate on the little boy because the tumour was the size of a grapefruit at that point.

After months of treatment, the first relieving news came: the tumour shrank to the size of a tangerine. Dexter could finally be operated on! After four long hours of waiting...waiting...waiting, the stone finally fell from his heart: the operation was a complete success and the tumour was completely removed. And Dexter? Three days after the operation, he was already walking through the hospital again and beaming with Marc.

After this nerve-wracking and painful experience, it was clear to Marc: he had to do something for the parents in this world. He wanted to create something useful and intelligent that would support parents in their everyday lives. From parents for parents.

This is exactly how Sandy was finally born. And with this enchanting product also something more, namely the Sandy family. A family that, together with Marc, brings his vision to life.

Because we care.


Erster Sandy Prototyp

April 2017 – First Product Design

As early as 2017, the first product design for Sandy, still very functional in appearance, was completed. Although still a long way from today’s “most adorable baby monitor in the world”, this design laid the perfect foundation for Sandy’s electronics and software development.

June 2018 – An emotive look & the foundation of the company

Sandy gets a bit of character! This is our product design one year on from our first try. Sandy, then known as Benny, gets some feet, some little arms and the unique sleeping cap for the first time. What’s more, he not only gets a face, but can now be operated much more easily thanks to the integrated display and touchscreen. On June 19, 2018, Marc founds DOKOKI AG!

April 2019 – Smartphone operation

So that you can be closer to your loved ones with Sandy from anywhere in the world (where there is an internet connection), Sandy is connected to a smartphone app in spring 2019. This will allow parents, grandparents or even family friends to see and hear how the little one is getting on.

October 2019 – Our Office

An important milestone for DOKOKI AG. After months of working with our developers over video calls and Marc and Tobias being stuck in a 5m² room, moving into our own office is both a cause for celebration in itself and a huge boost to our productivity.

March 2020 – Sandy - the most adorable baby monitor

While everyone else is working diligently at developing technology and software, Sandy is achieving his final shape. Cute little guy, isn’t he? From this point on, the achievements come thick and fast. Preparations for the launch are in full swing; at the same time, the ‘DOKI’ buttons are born and the baby monitor becomes an audio player as well. Work proceeds apace, and it’s only getting faster.
