On CNBC's "Mad Money Lightning Round," Jim Cramer said no to RealReal Inc (NASDAQ:REAL). He is not a buyer because there are too many of these guys.

Mind Medicine (MindMed) Inc (NASDAQ:MNMD) is a great spec, said Cramer.

He likes Affirm Holdings Inc (NASDAQ:AFRM) and he is a buyer.

Fair Isaac Corporation (NYSE:FICO) now has competitors and they've got a better way to do loans so Cramer thinks that's a problem. He is not a buyer.

Cramer would hold Upwork Inc (NASDAQ:UPWK) for the long term. He likes the CEO.

He would wait for people to stop selling Butterfly Network Inc (NYSE:BFLY).

Cramer doesn't see a single reason to own DISH Network Corp (NASDAQ:DISH) other than the fact that Charlie Ergen runs it. He doesn't want to bet against him.
