Our client is building the foundational product layer for the next major wave of onchain participants: autonomous, always-on, and incentive-aware AI agents. Having spent years at the frontier of consumer crypto—converting human attention into millions of onchain actions—our client possesses a powerful engine of distribution, incentive coordination, and proof of action. As agents evolve into economic actors capable of reasoning, holding value, and responding to incentives, this established infrastructure serves as an unfair advantage to capture the emerging agentic economy.

Our client is seeking a visionary Head of Product to own the product vision and strategy. This individual will transition a fast-moving thesis into high-scale products utilized by both humans and agents. Operating as a peer to the executive leadership team, the successful candidate will build and scale the product function from scratch. This role is designed for a strategic leader who maintains a builder's mindset and is eager to execute at the ground level.
