Rust, Zig, Odin, Nim are probably the most popular. It's also not surprising IMHO, most software is created to scratch a particular itch of an individual. Also specifically for programming languages, LLVM made it possible for individuals to build their own pet language with relatively little effort
but still get competitive performance and target platform coverage.
Rust though didn’t gain traction until Mozilla adopted it. I guess we could say individuals always created programming languages but majority are sponsored and paid by orgs/companies.
Before LLVM it was much harder for individuals to build competitive programming languages though (edited my original post with that afterthought, apologies)
