There is a broader narrative that they are trying to point to that is LP money isn't showing up in the same way now that there are other opportunities to generate returns in the macro market. Combine that with geopolitical risks and public tech companies valuations getting crushed - the market isn't as plush as it was say 3-6 months ago. Also - look at SPACs - complete collapse of that market.
He's saying what any reasonable market watcher would say: the market is in a very turbulent time - very rich deal flow and easy money from 2021 is not what you will find in 2022 in the current environment.
Whether you believe him or not - that's your prerogative. I have found many founders to be mostly unaware of macroeconomic and/or the fundraising market conditions until they need to get money (not a slight but rather they need to focus their time elsewhere). This is a PSA to those people who need a bit of a heads up - SPAC dead, fundraising is slowing down dramatically, IPO market crickets). Hopefully it changes soon as we get some indicators we are back in a bull market and valuations get a reset to a more reasonable range.
