I don't know if you remember this device, known as the world's first motorcycle AR helmet, Skully? This device had no time in sight, received numerous support on the crowdfunding website, and was overwhelmed by the media.

Unfortunately, we did not wait until Skully shipped us. Its eponymous company, Skully, emailed the media and officially closed down.
Two weeks ago, Skully's board forced the founders Marcus and Mitch Weller to leave the company. However, after a few months of struggling, Skully finally closed down. Many employees, including technicians, have also been forced to leave, and the AR helmet e-commerce website that Skully once had high hopes for is also closed.

Skully confirmed that the company had exhausted its funds and had originally planned to sell itself to LeTV in China. Later, it failed to reach a series of disputes (including disputes between investors and acquirers).
The remaining executives once tried to save the company, and they even raised $6 million over the bridge, hoping to weather the storm. However, this $6 million is a drop in the bucket and it is already too late.
In a letter to consumers, Skully wrote:
In the past few weeks, our management team has tried to raise funds, but unforeseen challenges and situations have emerged that are beyond our control and we cannot do anything about it.
Skully said that according to the seventh US bankruptcy rule, users who previously provided Skully with $1,500 in crowdfunding funds will not be compensated. Skully said he was sorry in the letter.
Skully is actually a good performance product. Its head-up display information is integrated with sensors, microprocessors, and cameras inside the helmet. It also comes with a step-by-step navigation function. It can broadcast recommended routes at about 3 meters away from the driver. Skully calls this the Synapse system. In addition, the system uses an automatic zoom display technology, which means that the map is the clearest on the helmet regardless of the angle of the rider.

Skully helmets also have a rear view system. This rearview system is similar to a car's reverse image, but Skully's rearview camera is a real-time, panoramic view with no blind corners. The captured image is displayed directly below the header information and is easy to see. This technology allows drivers to easily and clearly understand the environment behind them, eliminating visual blind spots and keeping them safe. The helmet is connected to a smartphone via Bluetooth and has been used for 9 hours.
However, even if this is the case, Skully still falls to the point where it is today, do not know whether Skully's collapse will ring a bell for other startups?
