It’s a cliché to say that founders flounder, but unfortunately, that’s usually the case. Wild exceptions like Bill Gates, Steve Jobs, and Michael Dell aside, executives who start a business or project fizzle more often than not once they’ve gotten their venture on its feet.Entrepreneurs actually show their inability to switch to executive mode much earlier in the business development process than most people realize, as my stories will reveal. But the reasons executives fail to “scale”—that is, adapt their leadership capabilities to their growing businesses’ needs—remain fuzzy. It’s simply assumed that there’s an entrepreneurial personality and an executive personality—and never the twain shall meet. I don’t think that’s true. I believe most executives can learn to scale if they’re willing to take a step back and admit to themselves that their old ways no longer work.Over the past four years, I’ve worked closely with more than 100 entrepreneurs and seen them struggle to adapt as their companies grow beyond a handful of employees and launch a new product or service. In the process, I’ve observed that the habits and skills that make entrepreneurs successful can undermine their ability to lead larger organizations. The problem, in other words, is not so much one of leadership personality as of approach.I’ve identified three tendencies that work for leaders of business units or small companies but become Achilles’ heels for those same individuals when they try to manage larger organizations with diverse needs, departments, priorities, and constituencies.The first tendency is loyalty to comrades—the small band of colleagues there at the start of the enterprise. In entrepreneurial mode, you need to lead like you’re in charge of a combat unit on the wrong side of enemy lines, where it’s all for one and one for all. But blind loyalty can become a liability in managing a large, complex organization. The second tendency, task orientation—or focusing on the job at hand—is critical in driving toward, say, a big product launch, but excessive attention to detail can cause a large organization to lose its way. The third tendency, single-mindedness, is an important attribute in a visionary who wants to unleash a revolutionary product or service on the world. Yet this quality can harden into tunnel vision if the leader can’t become more expansive as the company grows. And the fourth tendency, working in isolation, is fine for the brilliant scientist focused on an ingenious idea. But it’s disastrous for a leader whose burgeoning organization must rely on the kindness of customers, investors, analysts, reporters, and other strangers.Startup Kudos is available on Amazon andwww.startupkudos.comIG: @ramialameBe Organized, Be Passionate, Be Structured
