I personally prefer to start companies and new ventures “all the time”.  Keep experimenting is my motto.

That said I have been more successful building on new ideas when the “market is not so good”.

Why? Since I have been largely working on software ideas, they involved hiring and building small technical teams.

It is “easier” to hire during a downturn is what I have seen.

While many folks prefer to stay at a large company to “weather the storm”, the good folks can get new opportunities all the time.

They tend to look for interesting new work that can keep them engaged for 2-3 years instead of treading water.
