Summary
🤩
Rockstar🎓
Top SchoolFederico Küllmer is a founder and serial entrepreneur with 8+ years building at the intersection of AI, blockchain infrastructure and Web3, best known for creating Ethermint/Evmos—the flagship EVM-on-Cosmos implementation that raised $27M from top crypto investors. He combines deep backend engineering in Go and protobuf/grpc with product and fundraising chops, having led core IBC and Cosmos SDK work used across hundreds of chains. Federico’s open-source contributions span protocol implementations, relayers, and verification tooling (notably contributions to evmos, ibc-go, cosmos-sdk and Sourcify), reflecting a knack for both core protocol design and developer-facing infrastructure. Based in Berlin, he builds modular, interoperable blockchains and developer SDKs while also founding new ventures, currently running Moneda after leading Evmos and other startups. A detail that sets him apart: he pairs low-level protocol refactors and simulation/test tooling with practical docs and testnet governance fixes, showing a rare blend of rigorous engineering and product-oriented execution.
