Too Long; Didn't Read
Entrepreneurs (and therefore their investors) have X amount of time and Y amount of money to create a successful product. Any investment that doesn’t align with reducing the most critical risks (the first of them being attaining product-market fit) leads to waste. In most new products today, the technological risk is minuscule in comparison with the risk of not having a product that solves it that does it. The problem begins in companies that are before or borderline to that stage. Measuring where the company is, in the progress towards PMF is the most tangible outcome.
