Rivo raises $3.1M to build self-driving money and end the Inertia Tax.

Rivo raises $3.1M to build self-driving money and end the Inertia Tax. Autonomous cash management startup founded by former Cruise and Amazon AI leader launches with backing from South Park Commons, Wisdom Ventures, Script Capital, 645 Ventures, and 20VC. SAN FRANCISCO-(BUSINESS WIRE)-Rivo, a consumer fintech building autonomous cash management on top of existing bank accounts, today launched out of beta alongside its $2.7 million seed round, bringing its total funding to $3.1 million. The round was backed by South Park Commons, Wisdom Ventures, Script Capital, 645 Ventures, 20VC, and angel investor and advisor Jag Duggal, former Chief Product Officer at Nubank. Rivo automatically moves idle household cash into higher-yielding accounts and returns funds before bills come due, without requiring users to switch banks or move money manually. The company is attacking the Inertia Tax: the gap between what consumers earn on idle checking balances and what banks earn holding those deposits. U.S. households and nonprofits held about $5.9 trillion in checkable deposits and currency at the end of Q1 2026, according to Federal Reserve data. Bank of America's consumer bank alone held about $945 billion in deposits late in 2025, and CEO Brian Moynihan described that deposit base as what drives the profitability in this company. The cost of that inertia is no longer abstract: in April 2026, a federal court approved a $425 million settlement against Capital One over a savings product that quietly paid loyal customers far less than newer ones. Rivo connects to a user's existing bank account, monitors cash flow in real time, and automatically moves idle balances into higher-yield US government Treasuries (securities protected by SIPC) through its banking partner, Jiko. Funds are returned before bills come due. Users don't change banks, don't move money manually, and don't change their behavior. "Most people aren't ignoring their money; they're busy, and the system was designed to profit from that," said Ambrish Tyagi, founder and CEO of Rivo. "Recommendation engines tell you what to do, but Rivo does it for you, every day, without needing your attention." A representative Rivo household is a dual-income couple earning over $100,000 a year with two kids, salaries deposited every two weeks, bills on autopay, and tens of thousands of dollars sitting in their checking account. They are financially responsible and on top of everything, yet they had no idea their idle balance was earning them close to 0.07%* while their bank earned at least the prevailing federal interest rate (e.g., 3.6%** or higher in the current environment). Once their accounts were connected to Rivo, that yield started accruing without anyone lifting a finger. "Ambrish and the Rivo team are working on a problem almost every consumer has, and almost no one notices," said Aditya Agarwal, General Partner at South Park Commons. "Rivo stood out because the product does not stop at advice. It moves real money, manages edge cases, and has to earn trust through execution." Before founding Rivo, Tyagi led AI at Cruise during the launch of its commercial robotaxi service in San Francisco and previously worked on applied AI at Amazon. What made self-driving difficult was never the open road, it was the hard cases: a cyclist swerving or a truck stopping where it shouldn't, and the system only worked once it could handle those. Personal finance is the same. Pay cycles shift, a bill lands early, a shared account runs low, a charge hits the day before rent. Rivo is built for those moments, knowing when to move money, when to bring it back, and when to do nothing. Rivo's founding team brings together the rare combination this problem requires, with leaders from Personal Capital (acquired for ~$1 billion), Mint, Capital One, JPMorgan Chase, Microsoft, and LinkedIn. Rivo is now out of beta and open to the public. Read the full announcement here. Disclosures: Rivo is a technology company, not a bank.

Following this strategy, those who join the new feature will also enjoy advantages that optimize everyday costs, such as a free 10 GB NuCel plan for the first six months and a special price for the segment after that period, in addition to NuTag with no monthly fee. Nubank Croma will also cover 80% of the HBO Max subscription and provide access to ChatGPT Go free of charge for six months.

"Advantages within our ecosystem, such as special NuCel plans, cashback, and investment products aligned with this audience's goals, complete a competitive proposal. This is our way of recognizing and deepening our relationship with those who choose and trust Nubank," adds the executive.

Brazilian fintech, nubank expands on U.S. and Mexico.

Brazilian fintech, nubank expands on U.S. and Mexico. Nubank, the Brazilian fintech that redefined banking for millions in Latin America, is entering one of its most ambitious chapters yet. With Mexico set to become its first full-fledged international bank operation on August 6, a U.S. national bank charter advancing through regulators, and a growing footprint across South America, the company is attempting what few foreign financial institutions have dared: conquering America's fortress-like banking market while consolidating dominance across the region. Mexico: from fintech to full bank. On August 6, 2026, Nubank México will officially transition into an institución de banca múltiple - a full banking license - following authorization from the country's banking regulator (CNBV) on July 9. This milestone makes Nu the largest digital bank in Mexico, serving more than 15 million clients, roughly 15% of the nation's adult population. The transition follows a planned technical migration on August 5, during which certain services such as SPEI transfers and app-based balance consultations will be temporarily unavailable between 17:30 and 22:00 local time. Nu's debit and credit cards will continue functioning throughout the process, and customer funds will remain secure. "Este marco es un punto de partida para continuarmos acompañando a nuestros clientes de cerca," said Armando Herrera, CEO of Nu México. "Operar como banco nos da las herramientas para evolucionar junto con ellos, manteniendo la misma esencia, simplicidad y transparencia de siempre, ahora con más posibilidades. Seguimos comprometidos con nuestro foco en consolidarnos como el banco más amado de México." Since arriving in Mexico in 2019, Nubank clients have collectively saved approximately $2.694 billion in fees, annual charges, and transfer costs, according to company data. The cultural impact is equally striking: 60% of Nu's Mexican customers say they now use less cash, and 86% rate the company's impact on their financial lives as "high," citing greater stability and control over their finances. The U.S. Gambit: learning from fintech failures. The American consumer-banking market has proven a graveyard for foreign digital upstarts. Germany's N26 exited in 2021 after just two years. Britain's Monzo shuttered its U.S. operations earlier this year. Even homegrown digital challenger Chime holds less than 5% market share after a decade and billions in investment. Undeterred, Nubank secured conditional approval from the Office of the Comptroller of the Currency in late January 2026 - a landmark green light for a non-U.S. fintech. The company filed its application in September 2025, and regulatory timelines require Nu to fully capitalize the new institution within 12 months and commence operations within 18 months, effectively targeting a 2027 launch. Unlike many predecessors, Nubank is approaching the U.S. market with deep pockets and proven discipline. The company plans to offer deposit accounts, credit cards, lending products, and digital asset custody once the charter is fully approved. Its strategy blends the low-fee, user-friendly model that upended Brazil's "big five" banks with a cautious, regulation-first approach - a stark contrast to the aggressive, capital-burning tactics that tripped up rivals. Geographic Reference A regional powerhouse. While the U.S. looms large, Nubank's regional engine is firing on all cylinders. The company now serves 135 million customers across Brazil (115 million), Mexico (15 million), and Colombia (nearly 5 million), with physical offices in São Paulo, Mexico City, Bogotá, and Buenos Aires. Beyond its core markets, Nubank has rolled out "International PIX" - its instant payment solution - to Chile and Argentina, extending the Brazilian payment innovation that recently hit 1 billion monthly transactions across the platform. The company also offers the Ultravioleta global account, allowing customers to manage multiple currencies within the same app, a feature tailored for Latin America's increasingly mobile population. Financial muscle to match the ambition. Nubank's expansion is backed by robust financials. In the first quarter of 2026, gross profit reached $1.88 billion (up 27% year-over-year), while net income hit $871 million (up 41% YoY). Fourth-quarter 2025 results showed revenue of $4.9 billion (up 45% YoY) and net income of $895 million (up 50% YoY), with an annualized return on equity of 33%. Despite a recent market correction - shares have fallen roughly 23% in 2026, valuing the company at approximately $63 billion - Nubank remains one of the most valuable financial institutions to emerge from the Global South. The road ahead. Nubank's strategy hinges on a delicate balance: leveraging its Latin American scale to fund a disciplined U.S. entry, while continuing to deepen relationships in markets where it already holds sway. As Armando Herrera's message from Mexico City suggests, the company's ambition isn't just to build another bank - but to become the most beloved bank across two continents. If successful, Nubank could accomplish what neither European nor British fintechs managed: cracking the U.S. market not through brute-force marketing, but through a proven formula of low-cost digital operations, relentless customer focus, and regulatory prudence. The world will be watching as August 6 dawns in Mexico - and as 2027 approaches in Washington.

Nubank buys Banco Porto Real and adds a banking license in Brazil to continue consolidating its financial leadership.

Nubank buys Banco Porto Real and adds a banking license in Brazil to continue consolidating its financial leadership. · Banco Porto Real founded in 1992, to comply with the new Central Bank regulation that requires a banking license for those who use the word "bank" in their brand · The acquisition does not impose additional capital requirements nor change the experience of Nubank's more than 115 million customers in Brazil. · So far this year, Nubank has also obtained a banking license in Mexico and preliminary approval to operate in the United States. Nubank, the digital financial institution founded in 2013 by David Vélez, Cristina Junqueira and Edward Wible, announced an agreement to acquire Banco Porto Real, based in Rio de Janeiro, specialized in wholesale credit. The operation, subject to approval by the Central Bank of Brazil, responds to the Joint Resolution, which requires a banking license for institutions that use the word 'bank' in their brand or communications. The acquisition is symbolic in terms of size: Banco Porto Real had only US$6.3 million in assets in March. However, its strategic value is key; the license will be added to those Nubank already operates as a Payment Institution, Credit and Financing Company, and Securities Brokerage, without imposing additional capital or liquidity requirements, and without changing the customer experience at all. A bank that already operates at a giant scale. Nubank is today the largest private financial institution in Brazil by number of customers, with more than 115 million users in the country. One in five Brazilian adults accessed an account, credit or savings tools thanks to the company, and it is the most chosen financial institution by Brazilians to concentrate salaries, payments and financial products. "Brazil is where Nubank was born, grew, and proved that fairer and simpler financial services are possible at scale. Thirteen years later, it remains our main focus, a market where we can still significantly expand our share," said David Vélez, founder and global CEO of Nubank. Regulatory expansion in three markets. The acquisition of Banco Porto Real is part of a wave of regulatory moves by Nubank in 2026: at the beginning of July it received the green light to operate as a bank in Mexico, its second largest market, and in January it received preliminary approval to carry out banking activities in the United States. For Brazil, the company also announced this year investments of US$8 million in the domestic market, almost double the amount of the previous two years. With a presence in Brazil, Colombia and Mexico, and a regulatory expansion strategy that advances in parallel in its three markets, Nubank consolidates its position as one of the digital banks with the greatest reach in Latin America, competing on equal footing with giants such as Itaú Unibanco, Banco do Brasil and Bradesco.

Marriott Bonvoy to enhance Nu Stadium, Miami Freedom Park fan experience.

Marriott Bonvoy to enhance Nu Stadium, Miami Freedom Park fan experience. Inter Miami CF has entered into a long-term sponsorship agreement with hospitality company Marriott Bonvoy focused on Miami Freedom Park and its centrepiece, Nu Stadium. In what is its first collaboration with a Major League Soccer (MLS) club, Marriott Bonvoy will serve as the official hotel partner and hotel loyalty program partner of Inter Miami and Miami Freedom Park, alongside holding founding partner status for the latter. As the official hotel loyalty program, Marriott Bonvoy - Marriott International's travel platform - will play a central role in elevating the fan experience through exclusive access, unique experiences, and once-in-a-lifetime opportunities connected to Inter Miami and Nu Stadium. Through Marriott Bonvoy Moments, members will be able to redeem points towards a collection of Inter Miami experiences, ranging from suite hospitality and behind-the-scenes pre-match access to immersive match day getaways. The partnership will also introduce a new 'Marriott Bonvoy VIP Entrance' at Nu Stadium for suite holders and guests with VIP seating, featuring prominent branding throughout the arrival journey, from exterior marquee signage to in-lobby touchpoints and digital displays. Shared ambition "Marriott Bonvoy is one of the world's leading hospitality brands, and this partnership reflects the shared ambition of two global brands committed to setting a new benchmark for sports and hospitality," said Xavier Asensi, president of business operations at Inter Miami. "Together, we're creating meaningful opportunities for Marriott Bonvoy members and our fans to connect with the club in new and unforgettable ways. Beyond that, having Marriott Bonvoy alongside us as a strategic partner for Miami Freedom Park reinforces our vision as we build one of the world's premier destinations where sports, hospitality, and entertainment come together." Mandy Gill, managing vice-president of brands, marketing and partnerships in the US and Canada for Marriott International, added: "Marriott Bonvoy's first official collaboration with a Major League Soccer club reflects Marriott's continued investment in the global game and our commitment to connecting members with the experiences they care most about. "Together, we're creating unique opportunities for fans to engage with IMCF and experience the energy of Miami in meaningful new ways." Inter Miami opened Nu Stadium with a 2-2 draw against Austin FC in April. Nu Stadium, which has a capacity of 26,700, serves as the centrepiece of Miami Freedom Park, a wide-ranging entertainment district that will also feature a 58-acre public park, community sports fields, entertainment-based retail and attractions, hotels, shops, office space, and an entertainment venue. Construction work on the stadium officially commenced in August 2023, with Nu, a Brazilian digital financial services company, acquiring naming rights to the stadium in March through a multi-year deal. In June 2025, HPE signed on as the first founding partner of Miami Freedom Park, with the deal intended to play a key role in offering "the most advanced and fan-focused destination in global sports and entertainment". It has since been joined by Baptist Health, Modelo and now Marriott Bonvoy. Miami Freedom Park's sponsor portfolio also names Nu, Royal Caribbean, Lowe's and Florida Blue as top-tier main partners.
