AI has transformed how we shop—predicting trends, powering virtual try-ons and streamlining fashion logistics. Yet some of the biggest pain points remain: endless scrolling, too many tabs and never knowing if you’ve overpaid. That’s the gap Phia aims to close.
Co-founded by Phoebe Gates, daughter of Bill Gates, and climate activist Sophia Kianni, Phia was born in a Stanford dorm room and launched in April 2025. The app, available on mobile and as a browser extension, compares prices across over 40,000 retailers and thrift platforms to show what an item really costs. Its hallmark feature, “Should I Buy This?”, instantly flags whether something is overpriced, fair or a genuine deal.
The mission is simple: make shopping smarter, fairer and more sustainable. In just five months, Phia has attracted more than 500,000 users, indexed billions of products and built over 5,000 brand partnerships. It also secured a US$8 million seed round led by Kleiner Perkins, joined by Hailey Bieber, Kris Jenner, Sara Blakely and Sheryl Sandberg—investors who bridge tech, retail and culture. “Phia is redefining how people make purchase decisions,” said Annie Case, partner at Kleiner Perkins.
Phia’s AI engine scans real-time data from more than 250 million products across its network, including Vestiaire Collective, StockX, eBay and Poshmark. Beyond comparing prices, the app helps users discover cheaper or more sustainable options by displaying pre-owned items next to new ones—helping users see the full spectrum of choices before they buy. It also evaluates how different brands perform over time, analysing how well their products hold resale value. This insight helps shoppers judge whether a purchase is likely to last in value or if opting for a second-hand version makes more sense. The result is a platform that naturally encourages circular shopping—keeping items in use longer through resale, repair or recycling—and resonates strongly with Gen Z and millennial values of sustainability and mindful spending.
By encouraging transparency and smarter choices, Phia signals a broader shift in consumer technology: one where AI doesn’t just automate decisions but empowers users to understand them. Instead of merely digitizing the act of shopping, Phia embodies data-driven accountability—using intelligent search to help consumers make informed and ethical choices in markets long clouded by complexity. Retail analysts believe this level of visibility could push brands to maintain accurate and competitive pricing. Skeptics, however, argue that Phia must evolve beyond comparison to create emotional connection and loyalty. Still, one fact stands out: algorithms are no longer just recommending what we buy—they’re rewriting how we decide.
With new funding powering GPU expansion and advanced personalization tools, Phia’s next step is to build a true AI shopping agent—one that helps people buy better, live smarter and rethink what it means to shop with purpose.

Where Hollywood magic meets AI intelligence — Hong Kong becomes the new stage for virtual humans.

In an era where pixels and intelligence converge, few companies bridge art and science as seamlessly as Digital Domain. Founded three decades ago by visionary filmmaker James Cameron, the company built its name through cinematic wizardry—bringing to life the impossible worlds of Titanic, The Curious Case of Benjamin Button and the Marvel universe. But today, its focus has evolved far beyond Hollywood: Digital Domain is reimagining the future of AI-driven virtual humans—and it’s doing so from right here in Hong Kong.
“AI and visual technology are merging faster than anyone imagined,” says William Wong, Chairman and CEO of Digital Domain. “For us, the question is not whether AI will reshape entertainment—it already has. The question is how we can extend that power into everyday life.”
Though globally recognized for its work on blockbuster films and AAA games, Digital Domain’s story is also deeply connected to Asia. A Hong Kong–listed company, it operates a network of production and research centers across North America, China and India. In 2024, it announced a major milestone—setting up a new R&D hub at Hong Kong Science Park focused on advancing artificial intelligence and virtual human technologies. “Our roots are in visual storytelling, but AI is unlocking a new frontier,” Wong says. “Hong Kong has been very proactive in promoting innovation and research, and with the right partnerships, we see real potential to make this a global R&D base.”
Building on that commitment, the company plans to invest about HK$200 million over five years, assembling a team of more than 40 professional talents specializing in computer vision, machine learning and digital production. For now, the team is still growing and has room to expand. “Talent is everything,” says Wong. “We want to grow local expertise while bringing in global experience to accelerate the learning curve.”
Digital Domain’s latest chapter revolves around one of AI’s most fascinating frontiers: the creation of virtual humans.
These are hyperrealistic, AI-powered virtual humans capable of speaking, moving and responding in real time. Using the advanced motion-capture and rendering techniques that transformed Hollywood visual effects, the company now builds digital personalities that appear on screens and in physical environments—serving in media, education, retail and even public services.
One of its most visible projects is “Aida”, the AI-powered presenter who delivers nightly weather reports on the Radio Television Hong Kong (RTHK). Another initiative, now in testing, will soon feature AI-powered concierges greeting travelers at airports, able to communicate in multiple languages and provide real-time personalized services. Similar collaborations are under way in healthcare, customer service and education.
“What’s exciting,” says Wong, “is that our technologies amplify human capability, helping to deliver better experiences, greater efficiency and higher capacity. AI-powered virtual humans can interact naturally, emotionally and in any language. They can help scale creativity and service, not replace it.”
To make that possible, Digital Domain has designed its system for compatibility and flexibility. It can connect to major AI models—from OpenAI and Google to Baidu—and operate across cloud platforms like AWS, Alibaba Cloud and Microsoft Azure. “It’s about openness,” says Wong. “Our clients can choose the AI brain that best fits their business.”
Establishing a permanent R&D base in Hong Kong marks a turning point for the company—and, in a broader sense, for the city’s technology ecosystem. With the support of the Office for Attracting Strategic Enterprises (OASES) in Hong Kong, Digital Domain hopes to make the city a creative hub where AI meets visual arts. “Hong Kong is the perfect meeting point,” Wong says. “It combines international exposure with a growing innovation ecosystem. We want to make it a hub for creative AI.”
As part of this effort, the company is also collaborating with universities such as the University of Hong Kong, City University of Hong Kong and Hong Kong Baptist University to co-develop new AI solutions and nurture the next generation of engineers. “The goal,” Wong notes, “is not just R&D for the sake of research—but R&D that translates into real-world impact.”
The collaboration with OASES underscores how both the company and the city share a vision for innovation-led growth. As Peter Yan King-shun, Director-General of OASES, notes, the initiative reflects Hong Kong’s growing strength as a global innovation and technology hub. “OASES was set up to attract high-potential enterprises from around the world across key sectors such as AI, data science, and cultural and creative technology,” he says. “Digital Domain’s new R&D center is a strong example of how Hong Kong can combine world-class talent, technology and creativity to drive innovation and global competitiveness.”
Digital Domain’s story mirrors the evolution of Hong Kong’s own innovation landscape—where creativity, technology and global ambition converge. From the big screen to the next generation of intelligent avatars, the company continues to prove that imagination is not bound by borders, but powered by the courage to reinvent what’s possible.
