4. Business Model Generation: A Handbook for Visionaries, Game Changers, and Challengers

by Alexander Osterwalder and Yves Pigneur

Gone are the days when you had to write up a 100-page business plan before launching a successful business.

So, if you’re serious about pulling together your ideas for your business, this book is incredibly helpful. If it’s good enough for 3M, Deloitte and NASA, it might just be worth your giving it a whirl, too. Want to try it before buying the book?
