About

๐Ÿ‘‹ Product leadership with hands in the build

Portrait of Davi Mattar

I'm a senior product manager focused on AI and data-driven growth. Over 10+ years I've worked across a startup accelerator I co-founded, a Brazilian fintech inside Natura & Co, a hospitality giant's rewards app, a Canadian brokerage, and now Hyatt's marketing technology stack.

The through-line is measurable outcomes: 5.7M+ users impacted, $165K+ in monthly revenue lifted, $358K+ in annual savings, and a GenAI platform supporting $20B+ in assets under administration.

I stay close to the build โ€” LangGraph orchestration, Python evaluation scripts, analytics instrumentation โ€” because AI products need product managers who can reason about failure modes, not just roadmaps.
