Partial disagree. Pay for good people to make the most out of the tools available. If there is something you need that would improve revenue then get it when it becomes clear but don't just buy top tier X because. Start-ups need as much runway as possible if things dip until the business model is sustainable. Edit: Even if the business looks sustainable just wait till a disaster like covid comes by and rocks your supply chain and your customers prioritize other expenses.
