Jason Calacanis , founder and CEO of Mahalo.com , says it is during times like these that we find out who the "real entrepreneurs" are and who are "the folks who play entrepreneurs for some portion of their lives." He has been having a lot of covnersations with company heads who are looking at dimishing capital as they fight for survival during the recession, and he tries to pull together all the issues and advice in one place on his newsletter (which is open to the public. We found it at BusinessWeek.com). The first step, according to Calacanis, is to find out if you are really up to the challenges ahead in the coming months. Are you, for example, comfortable with laying off half your staff again and again, having clients default on their bills, and going from genius to idiot (as Calacanis did in media coverage when his Silicon Alley Reporter went from hot success to dot-com bust). He gives 12 situations, and if you can't handle them, then he says to get out now. If you are in for the short, medium, and long haul, then you are going to learn a lot in the coming months: Even if you're 100% sure your company is going to crash in the next six months, you'll learn more from staying on board than you will from running. You'll also earn the respect of your peers and you'll learn exactly how people break down and lose their cool. You'll see how certain venture capitalists screw entrepreneurs, you'll see entrepreneurs screw VCs, and you'll watch the lawyers and landlords collect their vig the entire time. Most of all, you'll realize who you are and who your real friends are. Now, Calacanis says, it is time to figure out how much time your company has left--you "runway"-- and then put every part of your business through a stress test. You will likely have to cut some staff and/or salaries, and go through some serious negotiations with your landlord, vendors, even yourself. Read What to do if your Startup is Failing here .
