I love these kind of games. does anyone know any other games like this (on any site not just itch)
Its a fairly niche genre, but maybe PC Tycoon 2 on Steam, or Mobiles Tycoon by the same dev. On PC Tycoon 2 you can do things like develop CPU's and increase their stats.
There's Computer Tycoon, on Steam, which is more tycoon-like. For something that feels somewhat similar to Computer Tycoon, there's GearCity, where you develop cars.
