During which phase is revenue and cash flow a major concern for a business?

Revenue and cash flow become a major concern for a business during the "Survival of the Fittest" phase. This phase typically represents a critical period for a business, where it must establish itself in the market and begin generating sufficient revenue to cover its operating costs. During this phase, companies often face challenges such as competition, customer acquisition, and resource management, which all demand careful monitoring of cash flow. If a business does not manage its revenue effectively during this phase, it risks running into financial difficulties that could threaten its ability to continue operating. This concern for revenue and cash flow is crucial as it directly impacts the sustainability of the business and determines whether it will advance to more stable growth phases like maturity or success.
