"Andy has a clear understanding of what makes a successful product and where founders often go wrong. While the equation itself provides a 1,000-foot view, it's the individual details I loved. Practical advice on how to find your first customers, how to successfully onboard people, how to get them experiencing value as soon as possible, and how to keep them coming back for more. This is as close a step-by-step guide to startup success as I have seen. Great work." -Shreyas Doshi, Product Leader (ex-Stripe, Twitter, Google)
