I disagree. Growth is an attitude. I worked at startups and at mature companies. In a growth company you usually do not have to justify work in term of profitability but in terms of growth. Then when the company is sufficiently large different management is brought in and the company is made profitable. Budgets are put in place. If you want to get something done, you have to ask for budget, and justify the cost yearly.

At least from my experience.
