About Heleno Pioner

My work involves providing technical and economic advice on pricing, incentives, and supply-chain economics, supporting executive decision-making in complex, large-scale systems. I’m currently a Principal Economist at Amazon, where I partner closely with SVP and VP-level leaders on questions where pricing structure, incentive design, and operational economics materially affect growth, profitability, and long-term sustainability. My work focuses on making second-order effects visible and translating complex data into decision-ready economic insights.Much of my experience sits at the intersection of- Pricing and monetization strategy- Incentive design across suppliers, partners, and internal teams- P&L trade-offs under uncertaintyI typically operate as a senior individual contributor and thought partner, rather than as a people manager, working with leadership teams to- Pressure-test strategic assumptions- Clarify economic trade-offs- Anticipate behavioral and system-level responses to pricing or policy changes.This model has been most relevant in marketplace, logistics, technology, and fintech environments, where small design choices can create large downstream effects.I’ve supported leaders across global, multi-regional organizations, collaborating with teams in North America and EMEA, and contributing to decisions that require both economic rigor and practical execution.My work emphasizes technical depth without organizational overhead, enabling senior leaders to move faster on complex decisions
