Liron Shapira

Liron Shapira is a startup founder, angel investor, and host of Doom Debates, a podcast and YouTube show built to raise mainstream awareness of human extinction risk from artificial superintelligence. He is the cofounder and CEO of Relationship Hero, a Y Combinator-backed coaching service that has guided more than 100,000 clients, and was previously cofounder and CTO of the app-search company Quixey. A fixture of the online rationalist community, he is known for putting his probability of AI-caused doom near 50% by 2050, for his sharp public critiques of crypto and web3, and for turning a $10,000 early bet on Coinbase into roughly $6 million while still calling cryptocurrency essentially worthless.
