The initial grind is a part of the startup fairytale that I feel is so often overlooked, yet is often the most interesting.
It shows just how the founders built their engine, the pieces they had to forge, parts that needed to be jammed together in some way to just barely function, components that were thrown out for costing too much and working too little. Every successful startup has their own engine. Some may be exact replicas of others. They work because the problems they tackle have been well explored. And others are bespoke, tailored specifically to handle truly difficult problems, and which require an immense amount of exploration, experimentation, failure, and restarts. That's why an Instagram can take off with less refinement and horsepower than an Airbnb -- we've developed the tools and built the maps to tread on one terrain, but not the other.
