OpenAI raised $40 billion at a $300 billion valuation after pivoting away from its GPT Store.The delay in launching the GPT Store led to a high attrition rate, with only 159,000 out of over 3 million custom GPTs making it to the public store.The revenue-sharing program for developers promised by OpenAI never materialized, leaving creators without monetization.This instance highlights the lesson that sometimes letting go of beloved projects can lead to greater success for founders.
