Who Is Lucy Guo, the Youngest Self-Made Female Billionaire in the World?
Born in Fremont, California to Chinese immigrant parents, Guo showed an early aptitude for technology. As a child, she taught herself to code, eventually earning money by developing bots for online games. She enrolled at Carnegie Mellon University to study computer science but left after being selected for the prestigious Thiel Fellowship, which encourages young talents to forgo formal education in favor of entrepreneurial pursuits.
Guo's breakthrough came in 2016 when she co-founded Scale AI, a data-labeling company that became foundational to the growth of artificial intelligence technologies. Although she left the company in 2018 following internal disagreements, Guo retained nearly 5% equity. With Scale AI's recent valuation reaching $25 billion, that stake alone accounts for a significant portion of her wealth.
After her departure from Scale AI, Guo co-founded Backend Capital, a venture capital firm that has backed several successful startups. She then launched Passes in 2022, a creator-focused platform that helps influencers monetize fan interactions using AI-driven features. The company has since attracted high-profile names and raised $50 million across multiple funding rounds, achieving a valuation of $150 million.
Despite her accomplishments, Guo has faced controversy. Passes is currently the subject of a class-action lawsuit involving allegations of inappropriate content monetization. The company has firmly denied all accusations, calling the claims baseless.
Guo is known for her vibrant lifestyle and tireless work ethic, often working from early morning until midnight. She credits her productivity to efficiency, team collaboration, and regular exercise. Despite her financial success, Guo insists she doesn't feel she has 'made it,' and continues to seek new ways to innovate and lead.
From college dropout to billionaire tech founder, Lucy Guo's story is emblematic of a new generation of entrepreneurs reshaping the global economy — not only through technology but also through bold, often unconventional paths to success.

BRICS criticism brings Trump 10% tariff threat
US President Donald Trump threatened China, India, and some of the world's fastest-emerging economies with higher import tariffs, hitting back at BRICS criticism of his trade policies as the bloc meets Monday. The 11-nation grouping -- which also includes US allies Brazil, Saudi Arabia, and Indonesia -- is concluding a two-day summit in Rio de Janeiro. On Sunday, BRICS leaders described Trump's stop-start tariff wars as 'indiscriminate,' damaging, and illegal, drawing a late-night rebuke from the pugilistic US president. 'Any Country aligning themselves with the Anti-American policies of BRICS, will be charged an ADDITIONAL 10% Tariff. There will be no exceptions to this policy,' Trump wrote on social media. BRICS members account for about half the world's population and 40 percent of global economic output. Conceived two decades ago as a forum for fast-growing economies, BRICS has come to be seen as a Chinese-driven effort to curb US global influence. But it is a quickly expanding and often divergent grouping -- bringing together arch US foes like Iran and Russia, with some of Washington's closest allies in Latin America, the Middle East, Africa, and Asia. Some US allies inside the bloc had tried to blunt criticism of Trump by not mentioning him or the United States by name in their summit statement. Saudi Arabia -- one of the world's biggest purchasers of US high-tech weapons -- even kept its foreign minister away from Sunday's talks and a BRICS group photo of leaders, seemingly to avoid Washington's ire. But such diplomatic gestures were lost on the US president.

Trump threatens allies Japan, South Korea with 25% tariffs
President Donald Trump threatened Japan and South Korea with 25 percent tariffs yesterday, stepping up pressure on the two historical US allies and a dozen other economies to reach trade deals with Washington. Trump had said at the weekend that starting from Monday he would send a first batch of up to 15 letters to countries, informing them that he would reimpose harsh levies earlier postponed in April. In near-identically worded letters to the Japanese and South Korean leaders, Trump said the tariff hikes would apply from August 1 because their trading relationships with Washington were 'unfortunately, far from Reciprocal.' Trump warned the countries, both key US allies in East Asia, of an escalation if they responded to the duties. Currently, both countries have been hit with a 10% levy imposed on almost all US trading partners. But Trump said he was ready to lower the new levels if Japan and South Korea changed their trade policies: 'We will, perhaps, consider an adjustment to this letter.' Japan's Prime Minister Shigeru Ishiba said Sunday that he 'won't easily compromise' in trade talks with Washington. White House Press Secretary Karoline Leavitt told reporters Monday that Trump would sign an order later in the day to delay his July 9 deadline for steeper tariffs to take effect -- postponing their imposition to August 1. She added that besides Japan and South Korea, there would be approximately 12 other partners receiving letters from Trump soon. With the deadline extension, Leavitt said Trump would be setting out the 'reciprocal tariff rate' for economies in the coming month as negotiations continue. Trump originally announced sweeping tariffs on world economies on what he called 'Liberation Day' on April 2, claiming the United States was being 'ripped off.' Amid market turmoil, Trump then suspended the initial tariffs for 90 days, a deadline that would have expired Wednesday without the latest extension. While the Trump administration had signaled hopes of striking dozens of deals by July -- at one point boasting of '90 deals in 90 days' -- there have been limited results so far. 'Change their tune' Asked why Trump opted to start with South Korea, Leavitt said: 'It's the President's prerogative, and those are the countries he chose.' 'This announcement will send a chilling message to others,' said Asia Society Policy Institute Vice President Wendy Cutler. US Treasury Secretary Scott Bessent said Monday that there would be a number of deals coming up: 'We are going to have several announcements in the next 48 hours.' 'We've had a lot of people change their tune in terms of negotiations. So my mailbox was full last night with a lot of new offers, a lot of new proposals,' Bessent told CNBC. He added that he would meet with his Chinese counterpart in the coming weeks. On whether he was disappointed in the number of trade deals achieved so far, Trump's trade adviser Peter Navarro maintained that he is 'happy with the progress we've had.' 'Every country that we run a major deficit with is fully engaged,' he told CNBC on Monday. Trump has also threatened another 10% tariff on countries aligning themselves with the emerging BRICS nations, accusing them of 'Anti-American policies' after they slammed his duties at a summit. For now, partners are still rushing to avert Trump's tariffs altogether. The European Commission said that EU chief Ursula von der Leyen had a 'good exchange ' with Trump on trade when the pair spoke Sunday.

China hits back at EU
Announces reciprocal ban on major medical equipment contracts China hit back yesterday at an EU ban on Chinese firms from major medical equipment purchases with a reciprocal bar on European companies in the latest trade salvo between the two economies. China's finance ministry said in a statement that European Union companies, with the exception of "those with European capital established in China, will have to be excluded" from orders of more than 45 million yuan ($6.3 million). Chinese Foreign Minister Wang Yi visited the EU's headquarters, as well as France and Germany, over the past week in a bid to improve relations with the 27-member bloc. However, deep frictions remain over economic ties, including a yawning trade deficit of $357.1 billion between China and the EU. China's ban, which comes into effect from Sunday, covers a wide range of products, from prosthetic devices and parts to medical machinery and surgical instruments. Beijing's finance ministry also specified that the proportion of products from the EU could not exceed 50 percent in bids from non-European companies. The EU drew an angry response from Beijing, and an accusation of double standards, when it banned Chinese firms from government medical device purchases worth more than five million euros ($5.8 million) in retaliation for limits Beijing places on access to its own market. The European Commission said at the time the ban was a reaction to "China's longstanding exclusion of EU-made medical devices from Chinese government contracts". According to Brussels, just under 90 percent of public procurement contracts for medical devices in China "were subject to exclusionary and discriminatory measures" against EU firms. "China has repeatedly expressed, through bilateral dialogue, its willingness to resolve these disputes appropriately through consultations, dialogue and bilateral arrangements in the field of public procurement," China's commerce ministry said in a separate statement. Over the last three years, Brussels and Beijing have come into conflict in a number of economic sectors, including electric cars, the rail industry, solar panels and wind turbines.
