One specific, undeniable mechanism for this is as regards SEO. The longer your domain is up, the longer links to you are up, the more links you have accumulated, the higher your ability to rank for terms of interest is. If you get to the first page of the SERP for something, you will tend to accumulate more links over time. Winners win, and winners take most.<p>Even if your company gets shot out from under you, you very well might have a personal blog, portfolio site, or something which folks routinely cited when saying that you were doing X, Y, or Z. You can take that with you, as capital for your next adventure.<p>By the way, if you get a company shot out from under you, please don't just slap up a We're Closed sign and let the domain lapse. That makes the SEO in me want to wince. Your Internet reputation is worth money, and (modulo whatever your agreement is with investors as regards IP) you probably still own it even if the business is not functioning as a going concern. Point some links to your personal domain and, when time comes, your new project.
