Sanchay Mittal is a founder and engineering leader with eight years of experience building protocol-level systems and product-grade applications at the intersection of Web3 and AI. He has held early product and engineering roles at Polygon and Connext and contributed to high-profile open-source projects like Aave, Gitcoin, and the Connext monorepo, spanning smart contracts, Subgraph schema work, and full-stack bridging UX. As CEO of Ethify Labs he managed a distributed team delivering multiple commercial projects, and he has founded startups—QuantWealth and JrMike—shipping prototypes that blend LLMs, context-aware embeddings, and tradfi design (JrMike exited in a six-figure acquisition). Sanchay combines hands-on protocol engineering (POS bridge and meta-transaction work) with product strategy and quality/process management, enabling both research-driven and market-ready deliveries. He’s driven by curiosity about agentic systems and complex networks, and off-hours he sharpens focus through boxing and diving—habits that mirror his disciplined approach to building resilient, incentive-aligned systems.
