Yes, and quite often you are selling your company. Investors will try to push you out of the game if they see potential in your products. If you don't have a time-to-market-sensitive product you are usually better off grinding in the basement for a longer time than people wants you to believe.

If however, you have a very narrow window to be able to launch properly, or if your product is mostly visionary you need investors asap. Just don't expect to come out with a Zuckerberg deal, expect 1-2% of the company in the end and make sure you cash out during the entire road.
