Entrepreneurs come up with new ideas and start businesses based on them. They forgo the security of a salaried job in order to run their own endeavor, assuming all the risk in hopes of great rewards (for more, see: Are You an Entrepreneur?). A serial entrepreneur takes on this challenge repeatedly. Once a particular business is established, he or she delegates the responsibility of running its operations and moves on to other ventures. They may even sell earlier businesses. Serial entrepreneurs often experience windfall gains, as their companies are sold at high premiums or continue to generate profits without much effort on their part, while they train their focus on the next (potentially) big thing.

This article lists, in alphabetical order, the top serial entrepreneurs; it's not exhaustive nor is it a ranking.

  1. Andreas von Bechtolsheim: The co-founder of Sun Microsystems was instrumental in building the company, founded in 1982, into a billion-dollar business. In 1995, he left Sun and established Granite Systems which manufactured network switches. Within a year, it was sold to Cisco Systems for $220 million. He launched a server technology company called Kealia in 2001, which was sold to Sun Microsystems in 2004, bringing him back to the Sun management team. Following that, he co-founded Arista Networks in 2005, a high-speed networking firm. He also co-founded HighBAR ventures, a venture capital investment firm which has invested in many technology start-ups. He was one of the early investors in Google, in 1998, with an investment of $100,000, even before Google, Inc. (GOOG) was established as a company. His net worth, in 2015, is around $4.7 billion.
  2. Sir Richard Branson: The foundation of business conglomerate Virgin Group dates back to 1970, when the 20-year old Richard Branson started a mail-order record business. Today, the Virgin Group owns over 200 different companies and each is controlled by different shareholders. His diversified set of businesses spans across multiple products and services. For every successful company under the Virgin brand (like Virgin Atlantic and Virgin Music), there are many other Virgin companies which are (or were) unsuccessful (like Virgin Cola, Virgin Brides, Virgin Vodka and Virgin Clothing).

  3. Rod Drury: Drury is a New Zealand-based serial entrepreneur in the technology space. In 1995, he established Glazier Systems which focused on software development and consultancy services.

He went on to establish Xero in 2006, a software-as-a-service (SaaS) company. He also co-founded a company called Pacific Fiber, which attempted to build an internet cable connecting the United States with Australia and New Zealand, though it didn't succeed.
  4. Janus Friis and Niklas Zennström: These billionaire Scandinavian entrepreneurs have numerous tech ventures to their names. The peer-to-peer file sharing service called Kazaa was their brainchild. But the pair came into the limelight with Skype, which was the first prominent computer-to-computer voice and video calling service. They sold Skype to eBay, Inc. (EBAY) for $2.6 billion in 2005. 
  5. Omar Hamoui: Hamoui, who dropped out of the MBA program at The Wharton School of the University of Pennsylvania, has established four different companies.

  7. Josh Kopelman: Kopelman started his entrepreneurial spree while at Wharton. In 1992, he established Infonautics Corp., which successfully went public in 1996. In the next few years, he founded several online businesses, including Half.com for used books and music gadgets, and TurnTide, which was an anti-spam system. Half.com was acquired by eBay less than a year after it started, and TurnTide was purchased by Symantec Corp. (SYMC) within six months. Kopelman is currently the managing director of First Round Capital, which has been funding Internet companies for the last 20 years. His investments include Mint.com and StumbleUpon.
  8. Michael Rubin: With an estimated net worth of $2.7 billion in 2015, Michael Rubin is an established internet and sports serial entrepreneur. Even before he went to college, Rubin acquired a chain of five ski-shops in his hometown of Lafayette Hill, Pa. He later established KPR sports, a sports equipment company which hit $50 million revenues by 1995. His 1998 venture, Global Sports, which was later called GSI Commerce (a billion dollar e-commerce venture), was purchased by eBay for $2.4 billion. Later, eBay sold three consumer divisions back to Rubin, who merged them together to form the present-day Kynetic. It includes Fanatics, Inc., (sports merchandise seller), Rue La La (flash sale site) and ShopRunner (member-based service portal dedicated to online shoppers). Rubin has also invested in the Philadelphia 76ers basketball team and the New Jersey Devils hockey team. (See related: Go to College or Become an Entrepreneur?)
  9. The Samwer Brothers: Entrepreneurship isn’t just about unique ideas; it’s also about borrowing best practices and perfectly executing them. Based in Germany, The Samwer brothers Alexander, Marc and Oliver established Alando, which was known to be a replica of eBay. It was eventually sold to eBay in 1999 for $50 million. Their next venture called Jamba!, founded in 2000, offered SMS mobile content, including ringtones, online gaming, online dating and insurance services for mobile phones. Jamba! was sold to VeriSign in 2004, for $270 million. In 2007, they founded Rocket Internet SE, which served as a parent company used to replicate successful global businesses in local markets. It is now successfully involved in funding startups for various internet companies, including Foodpanda, Home24, Spotcap and HelloFresh. The Samwars were also early investors in Facebook in 2008. Each Samwar brother’s net worth is at least $1.2 billion.

In 1986, she established Harpo Productions, Inc., which owned the rights to the “The Oprah Winfrey Show” from 1988 onwards, establishing the foundation of her entrepreneurial ventures.

The Bottom Line

Entrepreneurial ventures can offer huge financial gains, but require dedication, time and energy--the vision to succeed and the courage to fail. Serial entrepreneurs work their way from one business to another, not merely sitting back and reaping the rewards of their past successes, but banking on their experience to start new ventures. Many of them have established themselves in a diversified set of businesses, and their successes as well as their failures provide important lessons for aspiring entrepreneurs.
