When it comes to bread, Reena Manji knows exactly what she’s doing. She treats her sourdough starters like (somewhat unruly) children. But when it comes to Reena’s actual family—and their constant meddling in her life—well, that recipe always ends in disaster.

Now Reena’s parents have found her yet another potential Good Muslim Husband. This one has the body of Captain America, a delicious British accent, and lives right across the hall. He’s the perfect, mouthwatering temptation . . . and completely ruined by the unwelcome side dish of parental interference.

Reena refuses to marry anyone who works for her father. She won’t be attracted to Nadim’s sweet charm or gorgeous lopsided smile. That is, until the baking opportunity of a lifetime presents itself: a couples’ cooking competition with the prize of her dreams. Reena will do anything to win—even asking Nadim to pretend they’re engaged. But when it comes to love, baking your bread doesn’t always mean you get to eat it too.

In 2009, a St. Louis glassblowing artist and recovering computer scientist named Jim McKelvey lost a sale because he couldn’t accept American Express cards. Frustrated by the high costs and difficulty of accepting credit card payments, McKelvey joined his friend Jack Dorsey (the cofounder of Twitter) to launch Square, a startup that would enable small merchants to accept credit card payments on their mobile phones. With no expertise or experience in the world of payments, they approached the problem of credit cards with a new perspective, questioning the industry’s assumptions, experimenting and innovating their way through early challenges, and achieving widespread adoption from merchants small and large.

But just as Square was taking off, Amazon launched a similar product, marketed it aggressively, and undercut Square on price. For most ordinary startups, this would have spelled the end. Instead, less than a year later, Amazon was in retreat and soon discontinued its service. How did Square beat the most dangerous company on the planet? Was it just luck? These questions motivated McKelvey to study what Square had done differently from all the other companies Amazon had killed. He eventually found the key: a strategy he calls the Innovation Stack.

McKelvey’s fascinating and humorous stories of Square’s early days are blended with historical examples of other world-changing companies built on the Innovation Stack to reveal a pattern of ground-breaking, competition-proof entrepreneurship that is rare but repeatable.

The Innovation Stack is a thrilling business narrative that’s much bigger than the story of Square. It is an irreverent first-person look inside the world of entrepreneurship, and a call to action for all of us to find the entrepreneur within ourselves and identify and fix unsolved problems–one crazy idea at a time.
