Despite it being a short week, as always, it was a busy busy time. Our regular Friday producer Grace was under the weather today, so Chris stepped in to help out.

And as noted at the top of the episode, we're running a survey. The survey is here, dear Equity family. Please fill it out so that we can keep making the show better.

That aside, here's what Danny and Natasha and Alex got into:

• Stack Overflow has a new owner, and a $1.8 billion sale price that is minting 61 new millionaires in the process.
• Katerra is dying, as in going to zero. As the company has been a regular feature of TechCrunch coverage, we had to discuss its end. You can also catch up on Greensill here if that's your jam.
• Back on the acquisition front, Etsy is buying Depop for $1.625 billion. Our take is that the deal makes good sense, even if it is not cheap.
• Amazon is now open to being sued after an overwhelming number of arbiration claims were filed. Also we get to talk about everyone's favorite judge's writing style.
• Unit raised money to help teams unionize; Chipper Cash raised a huge round for its fintech product; and One Concern underscores Danny's larger disaster tech thesis by raising $45 million.

That's all we got! If you have heard Equity before, take the survey. Thank you!
