The Four Steps to the Epiphany

Steve Blank·January 2020

I was rejected from Steve Blank’s class at Stanford, ENGR 245: Lean Launchpad, and so I resorted to reading this to learn from virtual Steve. The book describes a startup’s life in four stages: first is customer discovery, of finding the market that would fit a startup’s vision for a product; then is customer validation, seeing whether early customers would actually buy the product; next is customer creation, of putting efforts into driving adoption by mainstream customers; and the final step is company building, of setting missions, making departments, and so on. I found the actual details to be interesting though some parts repeat and the details feel too specific to B2B, which may just be a byproduct of Steve’s past experience. None of the business details were intuitive especially to engineering-types like me, and it was a good reminder that a business succeeds or fails not because of technology but because of how well it serves the needs and wants of the customer.

The key idea of Steve’s business philosophy is to first validate then scale, whether that be the hypothesized customer problem, target market, the product feature set, and even the sales and marketing strategies. Validation happens when a hypothesis is formed, is tested in the field, and comes back with positive results. Steve remarks that when a startup fails, or runs out of money, it’s usually because lots of cash were spent to quickly scale while assuming unvalidated hypotheses, and when the reality invalidates said hypotheses, the startup is out of valuable cash and has to undergo tough layoffs or shut down. This is the same philosophy of unit testing in computer science, where you make sure each part of a system works on its own before integrating into a bigger system – without unit testing, engineers can be left with a big system that fails and they have no idea which part is responsible.
