Business Insider identified Parra by examining archived versions of a website for a software-development company created by Fiatjaf that revealed that the person behind the company was also the operator of a hostel in southeastern Brazil. The hostel's website indicates it is operated by Parra, and Fiatjaf's Google Maps reviews indicate he spends time in the neighborhood where the hostel is. On Fiatjaf's Github account, the license for some software written by Fiatjaf is assigned to Parra. BI also found a copy of Parra's university thesis, which matches details he provided to Forbes in a 2023 interview. The magazine agreed not to reveal his real name and referred to him only as Fiatjaf.
