The startup sminno developed an analog sound amplifier for almost every smartphone. The foldable CESAtube can be easily plugged onto every loudspeaker port, no matter if positioned on the front, back or side of the device. It is fastened by an translucent silicon band, that gives you full control over your touch display. With CESAtube you can enjoy your favorite music, watch videos or make conference calls with perfectly enhanced sound.
We coached sminno during the development process and helped to take the idea from a first prototype closer to final production.
A coaching project in cooperation with Anna Holzapfel and Martin Hass.
