In the tech boom of the '90s, so-called "startups" would burn through millions of dollars of investor cash before seeing any revenue. They'd hire PR firms and launch national ad campaigns; they'd bring on big-name C-level executives; and they'd train an army of support staff--all before they had any customers. Webvan,, eToys, and countless others whose names are now forgotten went down this path, only to find that the massive demand they'd anticipated for their services never materialized.

Investors have wised up since. Validation is the name of the game: Your concept may look good on paper, your demo may look great, but you're never going to raise more than six figures without traction--enthusiastic beta testers, active users, or best of all, revenue. Today, the word "startup" suggests a handful of people working on a small product, collecting feedback, and iterating on that feedback. Rather than launching when everything is perfect, they launch when they have a "minimal viable product" (MVP). It's an approach that's been advocated for years by startup accelerator programs like Y Combinator and TechStars. And now Eric Ries has a name for it: "The Lean Startup." He's built a whole brand around the name--including a video series, a conference, and now this book--and attracted press coverage that's described it as a "radical new theory" (Wired).

So is it new? That depends on who you are. If you're already in the startup world, most of this book will sound familiar. That's not to say that Ries' writings are useless--the book contains some solid anecdotes (though not as many as I would've liked), and many entrepreneurs are aware that they're not iterating on feedback as quickly as they could be--but it does make the repetition of the theme tedious. Small feature set, gauge customer interest, repeat as fast as possible; got it.

To avoid limiting his audience, Ries has broadened his definition of "startup" to encompass virtually any human endeavor. So if you work at a large corporation, a government agency, or a non-profit: Good news! You, too, can apply lean startup principles! Unfortunately, the book offers few tangible lessons in that arena. Yes, all else being equal, having customer validation is a good thing. But what to make of Ries' aside that the iPod rested on assumptions validated by the success of the Walkman? By that same reckoning, Apple should have looked at the web-capable smartphone market in 2005--a small niche comprised of geeky professionals--and concluded that few people would want an iPhone. Or they might have looked at tablet computers in 2007--an even smaller niche--and reckoned that no one wanted an iPad. Apple is the antithesis of the lean startup. They have the resources to make big bets and shrug when they don't pay off. Startups can't.

It's a dichotomy Ries never really gets at: When should you be lean, constantly listening to feedback and reevaluating your direction, and when should you just keep moving toward your vision? That's the fundamental question of entrepreneurship. There's no one-size-fits-all answer.

As of the writing of this review (August 2011), the US economy is still in pretty bad shape, banks aren't lending and companies are sitting on piles of cash. It's a perfect time to launch a startup, but capital is scarce. Fortunately, there are options for aspiring entrepreneurs. The Lean Startup by Eric Ries (co-founder of internet company IMVU) is a great place to begin.

When I first received the book I was a little concerned that it would be more focused on brick and mortar businesses to the exclusion of internet and content type startups. However, Ries focuses on a variety of entrepreneurial situations from traditional, physical businesses to those only existent on the web. If you are operating a business or thinking about starting one, chances are Ries has addressed your situation in some capacity within the book's 290+ pages.

The Lean Startup is filled with technical information, but also interesting stories that back up the author's assertions. I like this model because it allowed me to see what he was talking about in a real world setting. I also appreciate his inclusive vision of entrepreneurship. For example, he thinks entrepreneur should be a job category in larger companies and goes on to address the needs of people who are in charge of starting new projects within big corporations.

In short, the lean startup model focuses on getting a minimum viable product to the market, then receiving customer feedback along the way to improve the product and pivot (take a new approach) if necessary. This, of course, is in contrast to the old way of doing business where a product is launched fully functional backed by extensive market research. This method can be successful, but it costs a lot of money, pivoting is difficult, and failure can harm the bottom line (think Microsoft Vista).

I'm starting my own business and found The Lean Startup incredibly helpful. It basically functions as a general "how to" book for the lean startup method. While everything wasn't equally helpful for me personally, his advice on minimum viable product, how to find the root of personnel failures, and the creation of meaningful metrics is priceless.

If you are starting a business or thinking about expanding one, I'd highly recommend this book. I know my business will be more successful because of it.

I've been reading Steve Blank's blogs on lean startups and product strategy since he started. Read his "The Four Steps to the Epiphany: Successful Strategies for Products that Win" or his "The Startup Owner's Manual: The Step-By-Step Guide for Building a Great Companyl" if you must read a book on this subject.

His work and mentoring apparently inspired Eric Ries to write this book, which is fine but he does a really bad job of representing the original concepts. Makes me wonder how much of them he really understood.

Apart from being overly verbal and having a lot of repetitive waste in the narrative he's also constantly promoting himself and/or his fantastic consultancy efforts for others. Up to the point of nausea for me. Entire book could probably be condensed in less than a 100 pages if his ego was removed.

Read the original work, leave this alone.

However the concepts Eric Ries tries to describe in this book are very valid and real! It is mostly Steve Blank that applied them to startups and the Toyota lean authors that originally created them. If you managed to finish this book and found the content interesting please, please, please read up on it. There is lots of material out there and this book is definitely not a sparkling gem of wisdom on this subject.

No need to waste your time on 350 pages while the author has one point repeated over and over: test your assumptions with a minimum viable product as early as possible instead of waiting to develop the "perfect" product that you have in your mind.

This is the first review I've written in two years. The Lean Startup left me dissapointed. The book isn't organized well, isn't concise and the manner in which Ries writes makes one feel the urge to skim-read. Its purpose seems anchored in positioning himself as a consultant for startups, and he broadens his definition of startups so that large companies (or perhaps big pocket consulting prospects?) can still benefit from learning the "methodologies" of the Lean Startup--whatever that is.

I never once came away from a reading session with a new, insightful idea. When you sift away all the verbal drivel in the book, the main thesis or lesson is to do one thing: test.

All said, I don't regret my decision to read the book. With this much buzz around a book, I thought it worth a read. Unfortunately it was just buzz.

(Please excuse typos. Wrote this on phone)

The title may seem over the top, but actually the implications of Eric's new book are huge. I can't remember a text in recent years that predicted such significant conclusions for society, education, and world business.

**Concepts in the book that will make your head spin:

1) Ries's Law (I'm coining this right now) - Moore's Law that states the cost of new technology will rapidly decrease thereby reducing technological risk of innovation. It's not until The Lean Startup that we realize the cost of reaching customers and thereby market risk will also rapidly decrease.

2) Entrepreneur mythology as we know it is wrong (aka Steve Jobs is not what he seems). Iconic innovators ala the founders of Apple are believed by the public to be successful because of their creative vision of the future. The Lean Startup shows that in order for founders to be successful, they must test each element of there vision against reality.

3) Demystifying startup metrics. Even in a startup mecca like NYC, few entrepreneurs understand the metrics that drive their business. Eric's Innovation Accounting paradigm will change the early-stage VC industry as we know it.

**What I like about the book:

1) Comprehensive and a pleasure to read.

2) Real world examples (case studies) from tech startups to the non-profit industry. You will not find anything like these in other books.

3) Case studies in chapters 6 & 7 alone are worth the price of the whole book.

**What I don't like:

1) The chapter titles are a bit confusing and non-descriptive.

2) I could see some savvy entrepreneurs getting bored with the beginning when there's really great content in the later chapters. But if you're new to Lean Startup, the beginning chapters are a perfect introduction for you.

3) Some of the sources are outdates. I recently checked the links at the back of the book and gotten a couple 404's, but after searching on Google was able to find the sources. (this might be fixed now, not sure)

**Final Words
As someone who is very active on the latest research into innovation and entrepreneurship as well as an long-time entrepreneur myself, I love Eric's book and think that it's going to become a true classic and stand out as THE business book to read in 2011-2012. Don't listen to the haters, just look at the reviews from people like Marc Adreesen (founder of Netscape) and Dustin Moskovitz (cofounder of Facebook), these people don't endorse you unless you you are the real deal. Eric & The Lean Startup are the real deal.

Eric Ries is overly self absorbed and talks more about his company and himself more than any useful startup principles. I'd honestly have to say this is more of a biography of a company and, unlike the title leads you to believe, is aimed at changing large corporate American business ideals than actually helping startups. Another annoying fact is that he mentions his own concept "Lean Start-up" more than anything in the book - tooting his own horn.

2% helpful, 98% fluff. Not so much a "must-read."

If you haven't been reading any books or following blogs on entrepreneurship then you may find this to be a valuable read. If you already know about market testing, agile development methodologies, split testing, analytics and such things, then you really won't find anything new here that hasn't already been discussed for the past 5 to 10 years. In fact, I had to double-check the publication date of Sep 2011, since the book read more like a 2006-era book.

The two-star rating reflects my own personal dissatisfaction with the book since nothing new was introduced to me other than a label "The Lean Startup" which is somewhat of a misnomer. Much of the contents applies to fairly large groups either within existing organizations or as stand-alone organizations. Though some of the content applies to "2 guys in their basement", much of the content has a "larger" scope.

The contents of this book is so repetitive it's ridiculous. The same messages written over and over again just in a slightly different manner. It's as if the author assumes the reader is dumb and can't grasp the concepts. I found myself saying 'Ok, I get it already, so what about the HOW.' but it just goes around around in the same circles! Toward the end of the book there are some interesting points but overall I think there is a lot of unjustified hype around this book. It just doesn't deliver in every sentence like many awesome books do, nor does it even deliver in every chapter. Very disappointed that there are only a few valuable chapters in all.

I was anxious to read this book to gain some insight into applying the techniques of lean into my startup business. With a greenbelt and a couple LSS projects in my background I've been excited to take the techniques I learned when I was an employee and apply them to my own business. Disappointingly, this book was not very helpful in doing what I wanted. The author never gets down to the essential facts, or if he does, they are so wrapped in excess words that I couldn't distill them. My first read through the book turned into a skimming because I couldn't bear reading case study after case study with so much extra stuff that wasn't giving me insight into what to do. I decided to give it a second go and read it again, taking notes along the way, to try and pull out the important facts. The author seems to have devised his own set of terms, which I was fine with, until it dawned on me that the "minimum viable product" the author describes sounded a lot like a LSS pilot project. That got me wondering about what other Lean Startup concepts were simply LSS terms repackaged. The whole concept of "innovation accounting" never became clear to me, in fact while I was taking notes it started to seem like a circular argument was being made concerning the what and why of innovation accounting. I again started to quickly pass through the remainder of the book since I didn't see how I was going apply any rigorous, systematic processes since nothing was ever clearly laid out.

The author's mentioning of the idea of getting started and learning quickly along the way was helpful for allowing me to see what I am doing with my business and accept that it is an ok way to operate. Unfortunately, after two readings I don't have much to take away and apply to my business.
