Before Lakshmi Balachandra entered academia, she spent a few years working for two venture capital firms, where she routinely witnessed a phenomenon that mystified her. The VCs would receive a business plan from an entrepreneur, read it, and get excited. They’d do some research on the industry, and their enthusiasm would grow. So they’d invite the company founder in for a formal pitch meeting—and by the end of it they’d have absolutely no interest in making an investment. Why did a proposal that looked so promising on paper become a nonstarter when the person behind the plan actually pitched it? “That’s what led me to pursue a PhD,” says Balachandra, now an assistant professor at Babson College. “I wanted to break down and study the interaction between the VC and the entrepreneur.”
