Most startups break down no matter what the climate. An economic downturn may be a contributing factor, but not the main culprit.
First, the web continues to attract double-digit increases in advertising dollars. While this growth might slow, it seems unlikely to reverse. This means the web industry will continue to expand even if the economy as a whole does not.
Second, when the economy slows people tend to save and invest instead of spending. Given that many startups are driven by angel investment or venture funds, that's a good thing.
Third, web based and open source technologies are making huge gains in big business. They'll be increasingly attractive as companies tighten their belts. Given that the YC crowd is focused on this sort of development, that puts us in an enviable position.
I would start to worry if Google, Yahoo, Microsoft's web division, IAC, etc start making big layoffs. They could flood the market with competent programmers, driving down market rates and increasing competition for investment dollars. (Although I'm sure there are some companies fighting for talent that would love for that to happen.)
I think there's a greater risk of VCs moving to greener pastures - solar, biotech, etc - as web applications become commoditized.
It has reversed before, why does it seem unlikely now?
1. advertising dries up completely. 2. people tend to curb risky financial moves, such as early stage capital 3. businesses will cut back on almost all new development
The big question isn't, "Will it get bad?" but "Just how bad will it get?"
Jeff Bussgang does a nice job of explaining why VC funds are more attractive to investors during a downturn - http://bostonvcblog.typepad.com/vc/2008/01/whos-afraid-of.ht...
The sky is not falling.
Of course, optimism will spike when the new president takes office, and we'll see at least a short bubble early in 2009. Whether it will end up having a permanent impact on the economy is another matter...
Anyway, smart startups are better equipped to deal with downturns than larger companies, despite the common "retreat to quality" wisdom that a couple of articles have talked about recently. Fewer employees, the expectation to run unprofitably for a year or two built right in, and a much tighter fist holding the cash. Dumb startups would fail, regardless, and those businesses in between small startup and mid-sized business--the no mans land where many "successful" early stage startups fail--is probably even more dangerous during a downturn. So, be thankful you're a smart early stage startup! (And, if you're in no man's land with a million or ten in revenues and no clue how to scale to the next level and steadily increasing expenses, best of luck to you. You'll want to hang on tightly, keep your hands and feet in the car at all times, and hope the rails carry you out the other side safely.)
1. Make sure you are in good terms with your parents, or sister/brother, so if you loose your job, you can live in their basement for a while.
2. If you loose your job, now it is the best time to work on that idea... for reals. Necessity is the mother of all inventions.
