Yup, you can add your own here: https://www.levels.fyi/addcomp.html

I work for a company that was marked as "New" but there was no compensation. The levels were correct (close enough). Was wondering where you get the levels data from? Job postings? Or someone submitted levels w/o submitting compensation.

Levels can be submitted here: https://www.levels.fyi/create.html

Compensation we get separately through this form: https://www.levels.fyi/addcomp.html
