In the early stages, it's important to be cautious with spending and have a plan to reach profitability, even if you're reinvesting revenue into growth.

As a startup grows, it's crucial to monitor revenue per employee, ensuring that this number increases over time to avoid over-hiring and inefficiency.

You should know your bank balance, the money coming in, and the money going out to ensure your company's financial health.

As businesses scale, they care about two things: how much they spend and how much they make. We need to be better at showing how our product impacts those numbers.

Know your financial metrics, including net and gross revenue, to understand your gross margin and overall profitability.

Be cautious with paid growth, as it can be risky; if you pay for users who don't generate enough revenue, you could run out of money.

Sustainability in growth means not overspending beyond your means. If your customer acquisition costs exceed the lifetime value of your customers, you risk running into financial trouble.

Track the number of paying customers to measure growth; increasing customer acquisition rates can demonstrate to investors how quickly you're scaling.

You should regularly review your financial numbers, ideally at least weekly, to stay informed about your company's financial health.
