Instagram's Kevin Systrom — Keep it simple while scaling big

You can scale big with a simple idea (and a tiny team!) — but only if you catch the prevailing winds. That's what Kevin Systrom did when he co-founded Instagram: The simple photo app tapped the right trends, built on larger social networks, and dodged the complexities that would have slowed them down. The result? 30M users in 18 months. And a $1B sale of a 13-person company. With a cameo by Rohan Gunatillake (Buddhify).
