It doesn't matter. First of all, it is notoriously impossible for anyone except a few pros (if even them) to time the market. So don't even bother trying. Just live your life.

But second, even if you were sure that a recession was coming, you shouldn't let it affect your plans for starting a startup. Yes, funding does tend to dry up somewhat when the economy is bad. But if you look at startups that succeed vs. those that fail, the quality of what they built has much more effect on the final outcome than the state of the economy when they were getting started.

So this is yet another case of founders worrying about the wrong things. Recessions don't kill startups. Making mediocre stuff kills startups.
