David Roon

David Roon

The Technology Whisperer

Founder of Haoman

David Roon is a technologist and entrepreneur fascinated by how ideas become reality. Trained in Computer Science with a focus on distributed systems and AI, he began working on AI and NLP projects while still at university. His early work on Open Data and collaborations with statistical offices led him to discover blockchain and Ethereum in 2015.

As an early contributor to the Ethereum ecosystem, David co-founded OpenLaw within ConsenSys, pioneering the use of blockchain for legal automation. In 2020, that work evolved into The LAO, one of the first legally recognized decentralized venture funds, redefining how capital and collaboration can be managed online.

Through these experiences, David developed a deep passion for problem-solving—for turning complex challenges into meaningful, usable products. He's honed a rare talent for translating people's needs into clear technical solutions.

With Haoman, his latest venture, David aims to help others do the same: to turn bold ideas into working products through the right mix of support, structure, and technology.
