If you thought the tech world is full of hardcore geeks and nerds only, then think again. The field is so enticing, even Hollywood stars, TV personalities, musicians, professional athletes are trying out their fortunes.

For instance, Lady Gaga has invested in several tech startups including music sharing platform Turntable FM, and also celebrity social media site Backplane. Pop singer Kanye West is yet another celeb who has invested in Turntable FM.

The celebrity backup fittingly helps tech startups in two ways. One, they provide the financial backing. Two, they can use their influence to draw more investments and more than anything to accelerate the sale of products.

Not surprisingly, some of the celebrity investors have started looking beyond investing and have created their own apps.  Kim Kardashian’s Hollywood-inspired game, Kim Kardashian Hollywood, and Jay-Z’s streaming service Tidal are few of the recent examples. Kardashian has also established a pioneering online fashion subscription service ShoeDazzle. If you are interested in engineering an app similar to Kim Kardashian’s app, consult some top mobile app development companies in the world.
