About Gleb Dudka

Before becoming a venture investor, Gleb Dudka built and ran Deutsche Telekom's enterprise staking business, helped set up the company's first direct crypto investment in Celo, and has since focused deeply on staking, validator economics, and network yield, including writing a well-known multi-part series on staking and modeling how validator businesses work. He also brings a broader background to the role, having studied in Ukraine, Germany, and South Korea, taken part in EU blockchain policy discussions and advised the German government, and taught and mentored on blockchain topics in Berlin.

Greenfield focuses on backing early developer teams building the more open, decentralized side of crypto, leaning into DeFi early under a founder who had previously sold a startup to Opera, investing heavily in Europe (up to 70% of its latest fund), and treating clear rules like MiCA as an advantage rather than a risk. The fund has also built a research-heavy, repeated bet on digital fashion by leading funding rounds for both The Fabricant and DressX, based on the idea that NFTs let people own and resell digital clothing and identity across avatars, while opposing the idea of big tech companies like Apple or Facebook controlling the metaverse and running its own jobs portal to help portfolio companies hire.
