Here is something I (Zach) wrote up a while ago in an attempt to explain it:

> Back in 2016, we sold Zachtronics to a company called Alliance, who we worked for as employees and made all the Zachtronics games from SHENZHEN I/O onward. In 2022 we stopped working for them and started a new studio called Coincidence, which we own and run as a sort of co-op that allows us to work on projects together, or not together, or anything in-between. (By "we" I mean the five of us who made all the Zachtronics games from SHENZHEN I/O onward; the team was much more dynamic before that, as described in the first few pages of ZACH-LIKE.)

> I still work for Alliance and maintain the Zachtronics games, but we don't own any of that IP, so anything new we make is going to be attached to the new studio and the new name.

(I did spend a year teaching computer science at a public high school, but that overlapped the last year of Zachtronics, rather than being between Zachtronics and Coincidence like it's often reported.)

At Coincidence, we have released two puzzle games so far, Kaizen: A Factory Story and U.V.S. Nirmana, and have more (four?) in the works. I'm hoping that I'll get to work on some less-obviously-in-the-genre games soon, but I haven't git initted anything yet so I guess it's too early to say.
