l8orre, I definitely agree, this is why I am against scaling up too fast, it leads to uncontrollable spending. This IMO is what caused Ethereum a ton of grief, they had too high salaries, too many employees, too many development hubs arond the world etc. Simply too expensive. Brilliant developers with no business and management experience/interest. I recommend the 'Founders Dilemma' book to every future entrepreneur.
This is only a budget issue. It is not about how much you spend. It is about if your income or revenue (which can be the capital injection from the investors) can cover your spend and if the company's debt stricture is in a healthy level. More spending does not automatically mean a bad thing when today's spending will bring future values and revenue for the company.
It is important to have a valid business model when building a business. Where will the stream of cash and revenue come from to support the operation of the business? Who are the customers and clients? How do you sell your products? How much should you spend today to yield a goal in 5 years, 10 years, maybe 20 years? How much risk do you want to take?
