Current Focus
Doug is currently building and learning across LLM tooling, agents, evaluation, fine-tuning, and local inference. Since December 2025 he has been shipping PodwiseGPT, a conversational RAG layer for podcasts with transcription, per-episode embeddings, and multilingual chat with timestamped quotes.
Most recently he advised Hashgraph / Hedera on product strategy across the protocol surface area, including HTS, smart contracts, EVM compatibility, consensus, SDKs, mirror nodes, and asset tokenization, translating ecosystem and institutional needs into roadmap priorities.
Selected Work
Thesis · Head of Product, Project Lead
Doug led product for Threshold Network and tBTC, a fully decentralized BTC bridge to Ethereum and broader DeFi now securing 6,000+ BTC. He helped ship the first on-chain merger of two live protocols, built and managed a cross-functional team across five time zones, raised more than $8M in grants and ecosystem funding, and contributed to six live years with zero security incidents.
Rhombus · Co-Founder & CEO
At Rhombus, Doug built a high-throughput oracle engine that tethered real-world data to smart contracts, scaled the business to multi-year SaaS contracts with ConsenSys and MakerDAO, and negotiated the company's acquisition by Chainlink Labs, where Rhombus IP informed Proof-of-Reserve work.
ConsenSys · VP of Product
Doug incubated Rhombus inside ConsenSys and owned product across institutional Ethereum tools including Infura and Alethio analytics, helping grow adoption from zero to more than 65,000 weekly active developers while authoring the modular-oracle whitepaper that became a broader Web3 data blueprint.
Earlier Exits
Earlier, Doug co-founded v2 Ratings, an ML-driven quantitative investment data platform acquired by Xynon; founded Occom, later acquired by Originate; and helped build JobCompass, which was later sold. He also served as Director of Engineering at Collective Decision Engines, building a quadratic-voting market research product alongside Glen Weyl, Eric Posner, and Kevin Slavin.
Capabilities
Product & leadership: product strategy, roadmapping, OKRs, hiring, cross-functional team building, fundraising, go-to-market, and public speaking.
Blockchain & crypto: Ethereum, Bitcoin, Hedera / HTS, threshold and MPC cryptography, oracle networks, token economics, DAO governance, and tokenization / RWAs.
AI & engineering: LLMs and RAG, Python, PyTorch, scikit-learn, Rust, Go, Solidity, TypeScript, AWS, and GCP.
Education & Speaking
Doug holds a B.S. in Computer Science from Yale University. His published work includes the co-authored paper Quadratic Voting in the Wild: Real People, Real Votes, and he spoke at ETHDenver 2022 about lessons from the Threshold DAO merge.
