🌱 Principal at Greenfield Capital, a Berlin-based venture capital fund focused on supporting teams building towards Web3. Greenfield is currently the largest crypto fund in Europe by funds raised having recently raised a 3rd fund of $150m with more funds on the way. My focus is on DeFi and yield strategies as means of active network participation, conducting meaningful protocol work and providing infrastructure for the networks we support.


🥩 Founded and led a staking unit at T-Systems, Deutsche Telekom (Europe's largest telco, parent of T-Mobile). We were the first enterprise player in the world to offer Staking-as-a-Service and to engage in Generalized Mining on public blockchain networks, having turned the blockchain unit (in a #86 of Fortune500 company) into a mini crypto hedge fund. Fundraised for and led a small team that generated high 7-digit profits in less than a year by running nodes on Chainlink, Flow and Celo. Supported and helped structure the first enterprise token investment in Celo, based on the Network Lifecycle Investment thesis. Acquired Andreessen Horowitz (a16z) as a delegator to our Celo validator. Read more about our journey in my Infrastructure Thesis here.

💡 I’m an ex-editor and currently an advisor at We provide on-chain data, research and education around all things Proof-of-Stake (PoS) and overall yield-bearing crypto-asset class.
