Senior🎓
Top SchoolJohannes Pfeffer is a serial founder and blockchain-native technologist with 11 years of experience building data science and DeFi products, currently leading hiero.ai and co-founding corpus.ventures. He has been active in Ethereum since 2016, co-founded Alethio to deliver deep-chain analytics and later helped operationalize tokenized assets via the ACTUS protocol at atpar AG. His background combines a PhD in formal modeling from TU Dresden with hands-on roles in ontology design (EthOn) and blockchain standardization (ITIN), enabling rigorous, auditable systems for complex financial workflows. Comfortable at the intersection of research and product, he brings both academic rigor and startup speed to decentralised finance and analytics. An often-overlooked strength is his interdisciplinary grounding in mechatronics and human-machine interaction, which informs pragmatic, user-aware protocol and tooling design.
