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.

Sustainability has become more than just a buzzword—it’s a movement that’s reshaping business practices across industries. For small businesses, aligning with sustainable values isn’t just about doing the right thing; it’s about staying competitive in a world where consumers increasingly prioritize eco-conscious brands.
In the digital age, sustainable marketing is evolving rapidly, offering businesses new ways to reduce their environmental impact while engaging with customers who care deeply about the planet. Let’s take a closer look at the top trends driving sustainable marketing today and their implications for small businesses.
Most people don’t realize that online advertising has an environmental cost. Every time an ad is displayed, clicked on, or streamed as a video, it consumes energy. This energy powers the servers, data centers, and networks that host and deliver these ads. The problem is that much of this energy still comes from non-renewable sources like coal and natural gas, which contribute to carbon emissions.
For small businesses, this could mean optimizing ad campaigns to reduce unnecessary data usage or using platforms that offset their carbon emissions. Additionally, adopting lighter website designs and faster-loading ads can not only reduce energy consumption but also improve user experience—leading to better engagement and conversion rates.
Small businesses can stand out by making their digital campaigns both efficient and eco-friendly. Highlighting these efforts in marketing messages can appeal to sustainability-minded customers while showcasing innovation.
Sustainable packaging is no longer optional—it’s an expectation. But for small businesses, it’s not just about switching to biodegradable materials. It’s about effectively communicating those efforts to customers through digital channels.
Brands are using their websites, social media, and email marketing to share the stories behind their packaging choices. Whether it’s sourcing recycled materials or partnering with eco-friendly suppliers, transparency is key. Educational content, such as videos or infographics, can help customers understand the impact of their purchases and feel good about supporting a brand.
By using digital platforms to tell the story of their sustainability efforts, small businesses can create deeper emotional connections with customers. Sharing behind-the-scenes processes or celebrating packaging milestones can boost loyalty and differentiate a brand from competitors.
Influencer marketing has become a powerful tool for brands, and the rise of eco-conscious influencers is creating new opportunities for businesses that prioritize sustainability. These influencers focus on topics like waste reduction, ethical consumption, and eco-friendly lifestyles, making them an ideal partner for sustainable brands.
Collaborating with such influencers allows small businesses to reach niche audiences that are already committed to sustainable living. These partnerships feel more authentic compared to traditional ads, as followers trust influencers to recommend products that align with their values.
Even small businesses with limited budgets can benefit from micro-influencers —individuals with smaller but highly engaged audiences. Partnering with eco-conscious influencers can amplify a business’s sustainability message and create a ripple effect of awareness.
Consumers today are more skeptical of vague claims like "green" or "eco-friendly." They want specifics. Brands that embrace transparency by sharing measurable data about their sustainability efforts are earning trust and loyalty.
For example, brands that disclose the carbon footprint of their products or provide detailed information about their supply chains stand out in an age of greenwashing (misleading sustainability claims). This trend is particularly relevant for small businesses, as customers often expect smaller, local brands to be more ethical and transparent.
Being upfront about sustainability efforts—even if they’re still a work in progress—can build credibility. Sharing challenges, milestones, and small wins through social media or email newsletters makes the brand relatable and trustworthy.
The circular economy—a model in which products are reused, repaired, or recycled instead of discarded—is gaining momentum. Small businesses are finding creative ways to incorporate this principle into their operations and marketing.
For example, some businesses encourage customers to return used products in exchange for discounts or loyalty points. Others upcycle returned goods into new products and share this process with customers through digital platforms.
By participating in the circular economy, small businesses can differentiate themselves while building a loyal customer base. Promoting these initiatives online—whether through videos, blogs, or customer testimonials—can amplify their impact and attract eco-conscious buyers.
Sustainable marketing is more than a trend—it’s becoming a necessity for businesses of all sizes. For small businesses, it represents both an opportunity to stand out in a competitive market and a chance to make a meaningful impact on the planet.
Emerging trends like green digital advertising, circular economy initiatives, and transparency are reshaping how brands connect with their audiences. By embracing these practices, small businesses can attract eco-conscious consumers, build loyalty, and foster trust—all while reducing their environmental footprint.
The future of marketing belongs to those who see sustainability not as an add-on, but as the foundation of their growth. For small businesses ready to take on this challenge, the rewards go beyond profits—they include making a lasting, positive impact on the planet and the people who inhabit it.
