Welcome back to The TechCrunch Exchange, a weekly startups-and-markets newsletter for your weekend enjoyment. It’s broadly based on the weekday column that appears on Extra Crunch, but free. And it’s made just for you. You can sign up for the newsletter here. With that out of the way, let’s talk money, upstart companies and the latest spicy IPO rumors. (In time the top bit of the newsletter won’t get posted to the website, so do make sure to sign up if you want the whole thing!) BigCommerce isn’t worried about its IPO pricing One of the most interesting disconnects in the market today is how VC Twitter discusses successful IPOs and how the CEOs of those companies view their own public market debuts. If you read Twitter on an IPO day, you’ll often see VCs stomping around, shouting that IPOs are a racket and that they must be taken down now.
