Thiago Nigro disclosed the purchase on video in late December 2025, buying a Bitcoin ETF while BTC hovered ~US$87K, citing a need for more dollar-denominated exposure and concern about a potential 2026 financial crisis.
Nigro and Grupo Primo announced a partnership with Girassol Agrícola, a Mato Grosso firm farming 60k+ hectares of soy, corn, and cotton — the group's first major agro investment move.

O Primo Rico is the personal finance and investment channel built by Thiago Nigro, a Brazilian investor and entrepreneur whose handle translates loosely as 'the rich cousin' — a deliberate framing that positions him as the financially savvy relative willing to share what he knows. Nigro spent seven years working as an investment advisor before selling his firm and declaring financial independence in 2017, an origin story he mines heavily as proof of concept for his audience. That credibility forms the backbone of his content: a mix of accessible investment explainers, candid financial audits of celebrities (including a widely shared episode walking through zoologist Richard Rasmussen's finances), and sit-down interviews with established market figures such as veteran investor Luiz Barsi. His YouTube channel anchors the operation with millions of subscribers and engagement well above category norms, while a significant TikTok presence extends his reach into shorter, punchier formats.
The audience Nigro has built skews heavily male and spans a wide adult age range, with the 25–34 cohort at the core — a demographic actively making career and investment decisions, which gives his content practical urgency beyond entertainment. The Grupo Primo, the ecosystem he founded around the channel, has grown into an investment management platform with hundreds of thousands of active investors and tens of billions of reais under management, effectively turning a YouTube brand into a regulated financial business. Sponsor partnerships reflect this dual positioning: category-aligned names like Finclass and Investo ETF sit alongside aspirational brands such as BYD and Logitech, signaling that his audience is both financially motivated and consumer-active. As Brazil's retail investment market matures, Nigro is well-placed as one of the country's most commercially coherent creator-to-fintech crossover stories, with the Grupo Primo infrastructure giving his brand a durability that pure media channels rarely achieve.
O Primo Rico sits squarely in the Brazilian personal finance and investment education vertical, making it a natural fit for fintech platforms, investment products, digital banking, insurance, and financial-education services targeting Portuguese-speaking adults. The channel's content — built around wealth-building frameworks, entrepreneur interviews (notably a session with legendary investor Luiz Barsi), and real-money financial audits of public figures — signals a financially motivated audience concentrated almost entirely in Brazil, with a male-skewed, working-age composition. Engagement on YouTube runs well above the category median, indicating an audience that actively participates rather than passively scrolls, a meaningful quality signal for performance-minded sponsors. A consistent upload cadence across YouTube and TikTok sustains sponsor visibility across multiple touchpoints within the same week. The existing brand portfolio confirms broad commercial appeal: ETF platform Investo and educational service Finclass represent core fintech activations, while BYD and Logitech demonstrate that aspirational lifestyle and tech categories are also willing to pay for access to this audience. Insurance providers, digital brokerages, credit and lending products, and business SaaS platforms represent the most logical adjacent categories to activate next.

O Primo Rico's real name is Thiago Nigro. He built the channel under the 'O Primo Rico' brand, which translates to 'The Rich Cousin' in Portuguese — a name designed to position him as the financially savvy relative who shares investing secrets with the rest of the family.
Yes, Thiago Nigro married Maíra Cardi, one of Brazil's most prominent fitness influencers and life coaches, in 2022. The relationship drew significant media attention in Brazil given that both are major public figures with millions of online followers across their respective niches.
Before launching the channel, Thiago Nigro spent seven years working as a financial advisor. He achieved what he calls financial freedom in 2017 when he sold his investment advisory business, and immediately channeled that hands-on experience into building O Primo Rico and, later, Grupo Primo.
Grupo Primo is the financial education and investment ecosystem Thiago Nigro built around the O Primo Rico brand, with a stated mission of democratizing access to financial knowledge in Brazil. According to the channel's own bio, it now manages over R$20 billion and serves more than 200,000 investors, making it one of the largest creator-led financial platforms in the country.
O Primo Rico published a video titled 'Saving Richard Rasmussen's Finances,' revealing that the famous Brazilian naturalist and TV presenter reportedly had zero savings despite years in the public eye. The format — taking a real celebrity's financial situation and delivering blunt, educational advice — is one of his most viral content styles because it blends entertainment with practical investing lessons.
Luiz Barsi is Brazil's most celebrated individual stock market investor, often called the Brazilian Warren Buffett, who built generational wealth through disciplined long-term dividend investing. O Primo Rico hosted an 18-minute interview with him billed as 'brutally honest investment advice,' a sit-down that drew strong viewership given Barsi's near-legendary status among Brazilian retail investors.
'Rumo ao Bilhão' — Portuguese for 'Road to a Billion' — is one of O Primo Rico's signature content series, following the long-term journey of building extreme wealth. It gives the channel a running narrative arc beyond individual investment tips, turning personal finance into an ongoing story that keeps subscribers coming back.
Yes, BYD — the Chinese electric vehicle brand that has expanded aggressively into the Brazilian market — sponsored O Primo Rico's YouTube channel in 2025. The partnership makes sense given his audience skews heavily toward financially ambitious Brazilian men in their 20s to 40s, a demographic that overlaps with early EV adopters in the country.
Finclass is a Brazilian subscription-based platform offering video courses from top business, investing, and entrepreneurship figures. O Primo Rico has featured Finclass as a YouTube sponsor well into 2026, a natural fit since both brands target Brazilians who want to build wealth, and Finclass's content library directly complements the investing mindset the channel champions.
Lucro 2X — meaning 'Double Profit' — is a joint program between Grupo Primo and G4 Educação, one of Brazil's best-known business education companies. The collaboration pairs Grupo Primo's investment expertise with G4's entrepreneurship curriculum, and O Primo Rico actively promotes enrollment through his Instagram and other social channels.
