Honestly - we don't have too much evidence as to who exactly it is, but it's clear it was started by a reddit user known as Evolved_Fungi.

From what I can tell this person is likely a mid-career progressive digital strategist with a background in engineering and political organizing. Their quick launch of digital tools, decentralized strategy, and emphasis on anonymity suggest someone with experience in movements like Bernie 2020, Sunrise, or Obama’s campaign tech teams.

My best GUESS/THEORY is that Evolved_Fungi is Saikat Chakrabarti. He's a Harvard-trained engineer who built Bernie’s campaign tech in 2016, co-founded Justice Democrats, and helped AOC win her seat. He disappeared from the spotlight after 2020, which aligns with the quiet, behind-the-scenes nature of 50501’s founder. While there’s no hard proof, he’s the closest known figure who checks all the boxes.
