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.

In an era where social media reigns supreme, influencers have emerged as powerful players in the marketing game. They have the ability to sway opinions, drive trends, and create waves of engagement that brands can only dream of. But not all influencers are created equal; they come in various shapes and sizes, each with a unique approach to connecting with their audience. Under standing the different types of influencers can illuminate how they impact our daily lives and the choices we make. Let’s dive into the captivating world of influencers and explore the diverse categories that define them.
When you think of influencers, mega influencers are often the first that come to mind. These are the A-list celebrities, athletes, and global icons with millions of followers on platforms like Instagram, TikTok, and YouTube. Their immense reach allows brands to tap into vast audiences, making them highly sought after for endorsements.
Mega influencers have the power to generate instant buzz around a product or campaign. Their celebrity status lends credibility, and fans are often eager to emulate their lifestyles. However, this type of influencer can come with a hefty price tag, making them suitable for brands with substantial marketing budgets.
Just below the mega influencers are macro influencers, who typically boast between 100,000to 1 million followers. While they may not have the same level of fame as celebrities, macro influencers often command a loyal and engaged audience. They are usually experts in specific niches, such as fitness, beauty, travel, or technology.
Macro influencers combine reach with relevance. Their targeted expertise allows brands to connect with specific demographics, making them an ideal choice for campaigns aimed at niche markets. Their followers often view them as relatable and trustworthy, which can lead to higher engagement rates.
Micro influencers are the rising stars of the influencer world, typically having between 10,000 to 100,000 followers. What sets them apart is their authentic connection with their audience. They often have a more intimate relationship with their followers, leading to higher engagement and trust.
Brands are increasingly turning to micro influencers for their ability to create genuine conversations around products. The cost-effectiveness of partnering with micro influencers also allows brands to run multiple campaigns across different influencers, amplifying their reach while maintaining authenticity.
At the bottom of the influencer hierarchy are nano influencers, who have 1,000 to 10,000 followers. While their follower count may be modest, nano influencers often possess a highly engaged audience that views them as close friends, families or peers rather than celebrities.
Nano influencers are perfect for brands looking to create grassroots campaigns. Their genuine enthusiasm and relatability can lead to strong word-of-mouth marketing. Engaging with nano influencers often comes at a lower cost, making them an attractive option for small businesses and startups.
Brand ambassadors are influencers who have a long-term relationship with a brand, often representing them across multiple campaigns. They can fall into any of the previous categories but are distinguished by their commitment to the brand and its values.
By cultivating brand ambassadors, companies can create consistent messaging and foster loyalty among customers. These influencers often resonate with audiences more deeply, as they embody the brand’s identity and promote its products authentically over time.
The world of influencers is as diverse as it is dynamic, with each type offering unique advantages for brands looking to connect with consumers. From the glitzy allure of mega influencers to the genuine relatability of nano influencers, understanding these categories can help brands make informed choices in their marketing strategies. As the digital landscape continues to evolve, the role of influencers will only grow, shaping trends and driving engagement in ways we are just beginning to comprehend. By leveraging the right type of influencer, brands can effectively navigate this vibrant ecosystem, ensuring their message resonates with the audiences that matter most.
