He says a key reason that Airbnb and Uber are expected to go public soon is because they ignored some of those truisms early on and that how they approached their first 1,000 customers differently helps explain why they have millions of customers today. What did we learn by acquiring this customer and what did we learn by servicing this customer that we can use in the next customer and then in the next customer and again, and again, and again? As this cycle unfolds of learning how to acquire better and learning how to deliver the service or product better, over time naturally startup entrepreneurs start to reduce their amount of learning.
