Nubank Alum Launches Decade to Give Money an AI Copilot

Vitor Olivier, a former Nubank engineer, has founded a new company called Decade in an attempt to revolutionize the way people manage their investments. Decade recently raised an impressive $85 million in seed funding, making it the largest ever raised by a Latin American startup. The AI-driven platform aims to simplify investing in the same way mobile banking made handling everyday transactions more accessible.

Olivier, Decade's CEO and co-founder, believes that managing money should be as straightforward as banking. "Managing money is a second job," he said, explaining that Decade is betting that AI, paired with a flat fee, can finally take that job off people's hands. However, he acknowledges that financial services require deep expertise, relationships, trust, and long-term thinking, which an app alone cannot provide.

Decade's approach is to charge a relatively modest flat fee of about $40 a month, instead of commission-based models used by traditional investment advisors. This eliminates the incentive to push products with higher fees, as the company's income is not tied to sales. Customers get a platform that connects to their entire financial life through Brazil's open banking APIs, consolidating spending and investments, flagging high-fee products or tax inefficiencies, and providing on-demand access to a human advisor for bigger decisions.

The company's founders learned from their early attempts at building an automated advisory system. Initially, the models were not reliable enough for planning, math, or following multi-step instructions. However, the emergence of agentic AI, such as Anthropic's Claude Opus 4.5, has changed the game. With these capabilities, Decade can now provide a flexible, personalized investment experience that better reflects each user's complex financial life.

By leveraging AI, Decade can handle most routine questions, while a small portion of cases still requires human intervention. The founders' background in customer service at Nubank suggests that this approach could be highly efficient, as they managed a large customer base with a fraction of the headcount required by a legacy bank. Early results indicate that Decade's users are actively responding to the platform's recommendations, with usage data showing a significant reduction in flagged positions.
