If you thought that Skully's plan to crowdfund an augmented reality motorcycle helmet was overly ambitious... unfortunately, you were right. After years of delays and several weeks of grave financial trouble, the startup has informed backers that it's shutting down. Simply put, the company had run out of cash -- it had been scrambling to raise some temporary funding, but that fell through. TechCrunch sources claim that Skully had even been trying to sell itself to Chinese tech giant LeEco. However, it reportedly alienated investors following number of disputes over a possible sale, manufacturing hiccups and executive spending.
