Product operator and Atthena co-founder shipping an AI-native financial data platform for institutional investors.

Brazil

Message

At Atthena, I co-founded an AI-native data platform that turns Brazilian financial filings into citation-grade datasets for institutional analysts and AI agents. I own product and go-to-market, and shipped SaaS, REST API, and MCP-server delivery, driving 350+ organic waitlist signups in the first month with zero paid acquisition.

I also defined and delivered Atthena’s first production POC: an AI-embedded fund screener that analyzes funds and lets users edit screening results in-session. Before Atthena, I executed M&A and Debt Capital Markets mandates at Seneca Evercore and Singular Partners, and analyzed agribusiness credit at Grano Capital.
