criando o maior WEB3 VC da América Latina I WEB3 Top Voices 🇧🇷 I 2x Exit

i’m a venture strategist operating at the frontier of Web3 and Artificial General Intelligence (AGI). As founder of Proph3t Capital, I design, invest in, and build ventures that fuse emerging technologies with bold, market-driven execution.

My background blends over a decade of experience across innovation, crypto, venture building, and AI applications. I’ve launched companies from the ground up, scaled brands for global players like AB InBev and Bayer, and led go-to-market strategies for startups and VC funds in Latin America.

Today, I focus on creating and advising ventures at the convergence of decentralization and intelligence.

I believe Web3 and AGI are not just technologies — they are cultural shifts that will reshape how we learn, grow, heal, and transact. My work is dedicated to pushing the boundaries of what’s possible in these domains.

If you’re exploring the edge — of intelligence, autonomy, or decentralization — I’m always open to building what’s next.
