Let yourself be charmed by the toolkit and the case studies, along with the thoughts of Marc and Sharon.

Alex Osterwalder and Yves Pigneur, authors of the bestseller Business Model Generation

When two internationally-known experts in entrepreneurship write a “how to” book on market opportunities for entrepreneurs, it is bound to be a very valuable book indeed. Marc Gruber and Sharon Tal have created just the right book for first-time and experienced entrepreneurs. It contains both step-by-step plans and very valuable tips on identifying market opportunities – an invaluable complement to both the Lean Start-up Process and the Business Model Canvas!

Eric von Hippel, T. Wilson Professor of Innovation, MIT Sloan School of Management

From entrepreneurship thought leaders comes this innovative step-by-step guide to thinking through the market essentials of an opportunity. Rather than relying on generic examples or others’ stories, the authors put the reader in the “driver’s seat” by encouraging him or her to generate, evaluate, and prepare to act on their own opportunities. I can’t think of a more practically useful entrepreneurship book.

Dean A. Shepherd, Ray and Milann Siegfried Professor of Entrepreneurship,
Mendoza College of Business, Notre Dame University

Gruber and Tal have crafted a visually exciting way for entrepreneurs to identify and analyze their opportunities, before they dive into execution. This book pairs nicely with the Business Model Canvas and Lean Startup. Best of all, it also tells you how to focus, and what NOT to do!”

Henry Chesbrough, UC Berkeley Haas School of Business professor, and author of Open Innovation.

Using thoughtful research and compelling examples, Where to Play provides important guidance on how to balance focus and flexibility when launching a new venture. It builds on the Lean Startup model by providing meaningful insights on what markets to address first.

Tina Seelig, Professor of the Practice, Stanford School of Engineering

The market opportunity navigator attacks head-on one of the most difficult questions any aspiring entrepreneur must answer: ‘Which target market should I serve?’ It’s visual, easy-to-apply, and full of common-sense. If I were starting a business today, I wouldn’t leave the starting blocks without it!

Best-selling author and Professor John Mullins, London Business School: The New Business Road Test and The Customer-Funded Business
