I think Juan Lozano was making peroxide engines for early iterations of John Carmack's Armadillo Aerospace (whose website, sadly, is now only available via web archive...) EDIT: yes, AA is listed as a customer.

And very early on, Armadillo actually tested rotors with tip peroxide jets. Only ground tests that I know. Moved to pure rockets quickly. High test peroxide. Mixed monoprops with low grade peroxide and alcohol. Biprops. Peroxide-alcohol? Lox-alcohol? Lox-methane eventually.
