How Did Kevin Systrom and Mike Krieger Bond as Cofounders?

Kevin Systrom told Partners that most cofounder pairs fight and split, so planning another company with Mike Krieger was unusual. He compared the bond to people who had been through a hard posting together, with the caveat that Instagram was not that kind of stakes. Rivals had tried to kill the company and push one of them aside. After an exhausting argument with an investor, they sat in a bad restaurant on Market Street in San Francisco and ordered the greasiest thing on the menu. It was a low for the company and a high for him. Still liking each other after a year of long days, he said, is not something a couple of cafe prototypes can predict.
