The world of entrepreneurship news is a complex one, with people ever ready to give their two cents on how you should be running your business/VC fund/incubator.

Here’s our wrap of what we’re reading on celebs investing, 3D printers being taken off the watch list, the rise of the Middle East’s ecommerce market and old rich men getting away with too much.

That’s right, we used a Jay Z lyric and pivoted it to make a reference to the news that the rapper/music mogul is adding a venture fund to his business. With a focus on early stage startups, Arrive will be a new arm within his entertainment company Roc Nation. Jay Z is not new to the scene, he has been investing in tech since 2012.

Well, we think it’s time for the old guard to be called out. Just because you’re successful, rich and old it doesn’t give you a pass to make crass remarks.

MENA is dedicated to shopping online. You know the drill. The Middle East is a hugely untapped market when it comes to providing enough in the way of local ecommerce options. And not least when it comes to fashion. The stats are impressive. Net-a-Porter says that the average order value in the Middle East is 50 percent higher than the rest of world. So people are buying in - think Noon, for one. Incidentally, it's also been a great time for modest clothing brands, which are seeing a huge uptick in demand.
