    What failed startups don't have are enough customers.Founders and employees fail to spend time thinking about (and working on) traction in the same way they work on building a product. This shortsighted approach has startups trying random tactics - some ads, a blog post or two - in an unstructured way that's guaranteed to fail. This book changes that. Traction Book provides startup founders and employees with the framework successful companies have used to get traction. It allows you to think about which marketing channels make sense for you, given your industry and company stage. This framework has been used by founders like Jimmy Wales (Wikipedia), Alexis Ohanian (Reddit), Paul English (Kayak.com), and Alex Pachikov (Evernote) to build some of the biggest companies and organizations in the world. We interviewed each of the above founders - along with 35+ others - and pulled out the repeatable tactics and strategies they used to get traction. We then cover every possible marketing channel you can use to get traction, and show you which channels will be your key to growth. This book shows you how to grow at a time when getting traction is more important than ever. Below are the channels we cover in the book:Viral Marketing Public Relations (PR) Unconventional PR Search Engine Marketing (SEM) Social and Display Ads Offline Ads Search Engine Optimization (SEO) Content Marketing Email Marketing Engineering as Marketing Target Market Blogs Business Development (BD) Sales Affiliate Programs Existing Platforms Trade Shows Offline Events Speaking Engagements Community BuildingThis book draws on interviews with the following individuals: Jimmy Wales, Co-founder of Wikipedia Alexis Ohanian, Co-founder of reddit Eric Ries, Author of The Lean Startup Rand Fishkin, Founder of SEOmoz Noah Kagan, Founder of AppSumo Patrick McKenzie, CEO of Bingo Card Creator Sam Yagan, Co-founder of OkCupid Andrew Chen, Investor at 500 Startups Justin Kan, Founder of Justin.tv Mark Cramer, CEO of SurfCanyon Colin Nederkoorn, CEO of Customer.io Jason Cohen, Founder of WP Engine Chris Fralic, Partner at First Round Paul English, CEO of Kayak.com Rob Walling, Founder of MicroConf Brian Riley, Co-founder of SlidePad Steve Welch, Co-founder of DreamIt Jason Kincaid, Blogger at TechCrunch Nikhil Sethi, Founder of Adaptly Rick Perreault, CEO of Unbounce Alex Pachikov, Co-founder of Evernote David Skok, Partner at Matrix Ashish Kundra, CEO of myZamana David Hauser, Founder of Grasshopper Matt Monahan, CEO of Inflection Jeff Atwood, Co-founder of Discourse Dan Martell, CEO of Clarity.fm Chris McCann, Founder of StartupDigest Ryan Holiday, Exec at American Apparel Todd Vollmer, Enterprise Sales Veteran Sandi MacPherson, Founder of Quibb Andrew Warner, Founder of Mixergy Sean Murphy, Founder of SKMurphy Satish Dharmaraj, Partner at Redpoint Garry Tan, Partner at Y Combinator Steve Barsh, CEO of Packlate Michael Bodekaer, Co-founder of Smart Launch Zack Linford, Founder of Optimozo

     If you’re tired of the same old sales scripts or if you’ve done away with them all together, I know how you feel because I’ve been there. I was tired of seeing the same B.S.(bad sales) approaches and I wanted something that felt more natural for me. So I started creating my own scripts, for the simple reason that I hated being told, “No.” For me nothing was worse than that feeling of rejection. I was determined to figure out the perfect thing to say in every situation, and how to say it in a way that would cause sellers and buyers to want to say “Yes!” to me every time. This book is the result of that quest. And I’ve broken it in two unique parts so you can spend less time reading it, and more time using the life changing scripts inside. Part 1 will give you the foundation for making the scripts work for you. Not just some of the time, but every time! You’ll master how to inspire sellers to say “YES” to you giving you the magic key to unlock the success you want as a real estate agent. Part 2 Is the actual scripts that allow you to have smooth, choreographed conversations that lead you down the path to more success and more income. included in this section are… Prospecting Scripts for sellers that lead up to the listing appointment. My Unique Listing Presentation Scripts with examples of exactly how to deliver them for maximum impact. The Buyer Scripts that I’ve personally used for years to build my own real estate business from scratch. The Objection Scripts that will show you how to overcome any objection with ease and never be scrambling for words when a client throws you a curveball. In all there are 27 scripts in this book that will show you how to handle any situation, conversation, and objection that might come your way. And each script has been tested, tweaked and perfected. How do I know this? Because I’ve used each and every one of them to close millions of dollars worth of real estate in my nearly 2 decade career. I’ve also taken the time to include things I’ve picked up over my career that will help take you beyond the scripts… How to identify resistance and influence triggers so you can naturally use the right words and phrases that gets more clients saying YES to you. My practice techniques for memorizing and using these scripts to their full impact. You won’t just be pulling words from your memory, you’ll be speaking from the heart so you come across as genuine. The “tiny tweaks” that turn a regular script into something powerful. These seemingly little differences can have a huge impact in the way a prospect or client responds to what you say. The 9 Keys to more powerful conversations that go way beyond just the words you say to a client. I’ve mastered all 9 of these techniques and each one has made a huge difference in how I present myself to clients. The Book of YES is an action guide, not a book of theory. Think of it as YOUR PLAY BOOK for the key conversations you have with sellers and buyers.

    Across all of these break-out companies, a set of common patterns has evolved into a repeatable playbook that Gil has codified in High Growth Handbook. Covering key topics including the role of the CEO, managing your board, recruiting and managing an executive team, M&A, IPOs and late stage funding rounds, and interspersed with over a dozen interviews with some of the biggest names in Silicon Valley including Reid Hoffman (LinkedIn), Marc Andreessen (Andreessen Horowitz), and Aaron Levie (Box), High Growth Handbook presents crystal clear guidance for navigating the most complex challenges that confront leaders and operators in high-growth startups. In what Reid Hoffman, cofounder of LinkedIn and co-author of the #1 NYT bestsellers The Alliance and The Startup of You calls "a trenchant guide," High Growth Handbook is the playbook for turning a startup into a unicorn. "Elad Gil is one of Silicon Valley's seriously knowledgeable and battle-tested players. If you want the chance to turn your startup into the next Google or Twitter, then read this trenchant guide from someone who played key roles in the growth of these companies." - Reid Hoffman, co-founder of LinkedIn, co-author of the #1 NYT bestsellers "The Alliance" and "The Startup of You," and host of the podcast Masters of Scale "Elad eschews trite management aphorisms in favor of pragmatic and straight-shooting insights on complex topics like managing a board of directors, executing functional re-organizations with as little trauma as possible, and everything in-between." - Dick Costolo, former CEO of Twitter and serial entrepreneur "Elad first invested in Airbnb when we were less than 10 people and provided early advice on scaling the company. This book shares these learnings for the next generation of entrepreneurs." - Nathan Blecharczyk, cofounder of Airbnb, Chief Strategy Officer, and Chairman of Airbnb China "Elad jam-packs every useful lesson about building and scaling companies into a single, digestible book. My only gripe is that he didn't write this when we were in the early days of Box as it would have saved my ass countless times." -Aaron Levie, cofounder and CEO of Box "Armed with observations gathered scaling some of the most successful and important companies of Silicon Valley, Elad has no-nonsense, highly applicable advice to any operator transitioning a company from the proverbial garage to the next stage and beyond." - Max Levchin, cofounder and CEO of Affirm, cofounder and CTO of PayPal "Elad is one of the most experienced operators in Silicon Valley having seen numerous companies hit their inflection point. His advice has been key for Coinbase as we go through hypergrowth, from hiring executives to improving M&A." - Brian Armstrong, cofounder and CEO of Coinbase"Elad is one of the best connected and respected early stage investors in the Valley - he invested in Minted when we had fewer than 50 employees and his advice was critical to us in growing our business to where we are now, in the low hundreds of millions in sales. In his book, he crystallizes all of these learnings for the next generation of companies."-Mariam Naficy, cofounder and CEO of Minted

    At first I thought I was the only one who felt that way, but then I started to talk to people and realized we're becoming the "I'm, but" generation. When we talk about what we do for a living we inevitably say, "I'm a teacher, but I want to be an artist." "I'm a CPA, but I'd love to start my own business." "I'm a _____, but I want to be a ______." All too often, we hear that dreaming big means you quit your day job, sell everything you own, and move to Guam. But what if there were a different way? What if you could blow up your dream without blowing up your life? What if you could go for broke without going broke? What if you could start today? What if you already have everything you need to begin? From figuring out what your dream is to quitting in a way that exponentially increases your chance of success, Quitter is full of inspiring stories and actionable advice. This book is based on 12 years of cubicle living and my true story of cultivating a dream job that changed my life and the world in the process. It's time to close the gap between your day job and your dream job. It's time to be a Quitter.
