John Jantsch

John Jantsch (born April 2, 1960) is an author, speaker, and marketing consultant who specializes in assisting small businesses. He is the author of Duct Tape Marketing, The Referral Engine, and The Commitment Engine. Jantsch grew up in Kansas City and attended the University of Kansas. In 2002, Jantsch created the Duct Tape Marketing System, which trains and licenses small business consultants. Two years later, he added the Duct Tape Marketing Consultant Network.

Duct Tape Marketing offers marketing workshops and consulting to small businesses looking to expand. Jantsch suggests treating small business marketing systematically and not creating individual "marketing events." One way to do this, Jantsch says, is to maintain a strong and consistent internet presence through blogs, social media, and forums tailored to small business interests.

In 2007, Jantsch published Duct Tape Marketing: The World's Most Practical Small Business Marketing Guide, which outlines his systematic approach to marketing. The book is divided into three parts. Part I is titled "The Duct Tape Foundation—The Way to Sticky Marketing" and deals with laying the groundwork for a successful marketing system. Part II is titled "The Duct Tape Lead Generation Machine—Turning Stickiness Into a System That Works for You," and it focuses on implementing the strategies of Part I. Part III is titled "Getting on a Roll!" and it serves as a conclusion meant to ground the preceding two parts.

Michael Gerber said Duct Tape Marketing is "just like its namesake – Duct Tape – it's good, incredibly smart, amazingly practical, and immensely sticky stuff." Duct Tape Marketing Revised & Updated was published in 2011. In 2010, Jantsch published The Referral Engine: Teaching Your Business to Market Itself. The book outlines an approach to marketing that moves away from complicated marketing campaigns and instead focuses on personal interactions with customers through outlets such as social media and friend-to-friend word of mouth. 

The idea, Jantsch writes, is that a business should always focus on and understand the importance of referrals. The Referral Engine was a Wall Street Journal bestseller, a Small Business Trends "Editor's Choice Best Business Books 2010," and Library Journal's "Best Marketing Book 2010." It was on 800-CEO-READ's "Best Business Book of 2010" shortlist. The Commitment Engine: Making Work Worth It is directed at helping business owners establish lasting commitment in their employees, customers, and businesses and examines what makes some businesses worth referring.

The book diagnoses the key qualities of successful, "effortless" business approaches. The Commitment Engine has been featured in Forbes, CNBC, and The New York Enterprise Report and was reviewed positively by Trust Agents author Chris Brogan. Jantsch has given a TEDx talk about the book. In 2016 John Jantsch and co-author Phil Singleton published SEO for Growth - The Ultimate Guide for Marketers, Web Designers, and Entrepreneurs. 

The book is aimed at teaching marketers, designers, and entrepreneurs the strategic nature of search engine optimization as well as the SEO forces at play in web design and social media. Excerpts from SEO for Growth have appeared in Entrepreneur, Copyblogger, and Search Engine Journal, as well as on MSNBC. Jantsch's Duct Tape Marketing blog was chosen as a Forbes favorite for marketing and small business, and his Duct Tape Marketing podcast was called a "must listen" by Fast Company magazine. 

Jantsch has delivered keynote speeches to organizations such as American Express, Microsoft, Verizon, HP, and eBay. He also is the featured marketing contributor to American Express OPENForum. Jantsch's small business advice has been featured in New York Times, Wall St. Journal, and CNNMoney, among others. Seth Godin called Jantsch the "Peter Drucker of small business tactics."
