Specific anecdote - SaaS companies selling to other SaaS companies is going to cause a mini-winter in that sector. My company (which we thankfully sold last year :praise) had several (though not exclusively) high-growth tech companies as customers.

Now, when I look at layoff announcements, I see a lot of our former customers. Additionally, with budget freezes (driven by VC RIP decks), these same companies aren't buying new software for a while, even if they would benefit from it. And many tools now are priced based on headcount. So it's sort of the perfect storm - valuation resets so you have to go a lot farther with your current funding, reduced retention revenue because your customers are paying for fewer seats and harder sales because of budget freezes. Ick.
