In any fast growing company, it's natural that conflict arises. It holds true at just about any company -- every type, every stage. Doesn't matter what market or size.
You'll see it happen most between functional areas. Sometimes marketing and operations will be at odds. Sometimes, it's marketing and sales, or sales and finance. Technology may want to go one direction, marketing another. Finance might lean too conservative.
It's why it's super important for your leadership team to have strong interpersonal skills and interactions. You can't rely on hiring great people alone. You also need to set the pace for solid interactions, help create and foster them. Nurture it at every turn.
