I hear these three terms used interchangeably, but in my mind, they all mean slightly different things. It\u2019s semantics, of course, but here\u2019s my take on what these three words mean. Which do you identify with the most? Small Business Wikipedia: A small business is a business that is privately owned and operated, with a small number of employees and relatively low volume of sales. Small businesses are normally privately owned corporations, partnerships, or sole proprietorships. The legal definition of "small" varies by country and by industry, ranging from fewer than 15 employees under the Australian Fair Work Act 2009, 50 employees in the European Union, and fewer than 500 employees to qualify for many U.S. Small Business Administration programs. Small businesses can also be classified according to other methods such as sales, assets, or net profits. Me: In my mind, small businesses are those boutiques, hair salons, yoga studios, etc. you walk by downtown. \u201cSmall business\u201d to me connotes a brick-and-mortar location. Employees are a must, even if it\u2019s your wife and daughter. Small businesses may use more \u201cold school\u201d forms of marketing, like print ads or television commercials, rather than social media and the internet. You might have a small business if\u2026 You\u2019re a member of your Chamber of Commerce. You have a family business passed down through generations. You work 100 percent (or 150 percent) at your small business (it\u2019s your full-time job). You sell or manufacture a product. Entrepreneur Wikipedia: An entrepreneur is a person who has possession of a new enterprise, venture or idea and is accountable for the inherent risks and the outcome. The term was originally from the French and was first defined by the Irish-French economist Richard Cantillon. Entrepreneur in English is a term applied to a person who is willing to launch a new venture or enterprise and accept full responsibility for the outcome. Jean-Baptiste Say, a French economist, is believed to have coined the word "entrepreneur" in the 19th century - he defined an entrepreneur as "one who undertakes an enterprise, especially a contractor, acting as intermediatory between capital and labour." Me: This is the one I most identify with. Entrepreneurs may\u00a0 have employees, but often go it alone as solopreneurs. They\u2019re willing to take risks for the reward (though maybe not as much as a startup). Entrepreneurs are all about social media, at least the ones I know. You might be an entrepreneur if\u2026 The idea of failure doesn\u2019t scare you\u2026too much. You use social media to market your business\u2026and do it all yourself. You tend to do all the work and have trouble delegating You have started more than one business (successfully or not). Startup Wikipedia: A startup company or startup is a company with a limited operating history. These companies, generally newly created, are in a phase of development and research for markets. The term became popular internationally during the dot-com bubble when a great number of dot-com companies were founded. A high tech startup company is a startup company specialized in a high tech industry. Me: I definitely think of tech companies when I think of startups, although I see non-tech companies claim the title. To me, startups are like fuses: They light brightly very quickly, but the fuse is short. At the end of it, the startup turns to another form, like part of a corporation that buys it, or it becomes a small business. Also, I tend to associate getting funded or working with angel investors with startups only. You might be an startup if\u2026 You\u2019re starting your company while working 40 hours a week at a day job. You fly to Silicon Valley at the drop of a hat to meet someone with deep pockets and good contacts. You know what a term sheet is. I realize this post will incite some aggressive great dialogue around the definitions I\u2019ve laid out here, and I welcome it. After all, it\u2019s all subjective, isn\u2019t it?
