What happened to them? I can't find much information about them. Only 4 visual novels.

The incest fad burnt out for a while, then their owners started more companies doing harem and less dark, less plot-focused visual novels.  Hulotte and Cube, for instance...

For the company, I suppose they're already quietly disbanded and went back to the main company, Cuffs, or maybe Cuffs decided to not use the name anymore unless when something happen with one of its product, such as when Yosuga no Sora was abut to be released in the Steam (Chinese language only) with Cuffs listed Sphere was still listed as the developer for it. For more information on Yosuga no Sora staffs, the writer are only wrote all game made by Sphere while the director got some more works until Enki Dekinai with he got special thanks.
