I was referring to working for a startup than founding one. I think you are right about founding, that many founders will be older necessarily. And in that case, you at least have controls of the risks and are chasing your vision, not someone else's. But working for a startup at 40 seems problematic, since you aren't really taking risks as an entrepreneur.

I don't believe the original post was about working at a startup, it was more regarding founding one. Hence my answers to that effect.

I don't see the difference though. Netscape was co-founded by a 20-something Marc Andreessen, but run day-to-day by a couple 40-and-50-somethings in the early days, not including the developers, many of which were well into their 30's.

Like I said, the 20-something startup kid - either worker or founder - is a stereotype and not accurate. I can keep coming up with more examples if you want. There are dozens of them for every one 20-something wunderkind example.

Heck, looking back now that I'm in my 30's, I marvel at the ignorance I had in my 20's that could have easily led me to ruining a startup. Experience is simply irreplaceable and more valuable than youth in business, regardless of what you've been told.

Now that I'm a little older, I have a successful company which I could simply not have achieved without millions of dollars in investment at a younger age. That investment would have all gone to keeping me afloat while I made mistakes due to the naivete of my 20's. Contrarily, working in industry for a little while first, I learned from other successful companies and leveraged the good things while jettisoning the bad things I saw.
