Bill Gates' daughter Phoebe and Stanford roommate Sophia Kianni just closed an $8 million seed round for their fashion comparison app Phia in just three-and-a-half weeks. The lightning-fast funding, led by Kleiner Perkins with celebrity investors like Kris Jenner and Hailey Bieber, signals how Gen Z founders are rewriting startup playbooks with social media-first strategies and powerful network effects.
Phia just pulled off what most startups can only dream of - an $8 million seed round closed in three-and-a-half weeks. But this isn't just another Silicon Valley funding story. It's a masterclass in how Gen Z founders are leveraging social media, celebrity networks, and radical transparency to accelerate startup growth.
Phoebe Gates, 23-year-old daughter of Microsoft founder Bill Gates, and her Stanford roommate Sophia Kianni have built what they call 'Google Flights for fashion' - a mobile app and browser extension that searches across 300 million fashion items to help users compare prices. Since launching in April, Phia has already amassed 500,000 users.
'As we think about what the future of fashion is going to be like five years from now, it's all going to be about making access a lot easier to things that people haven't had access to before,' Gates told TechCrunch in an exclusive interview.
The funding round reads like a who's who of business and entertainment. Kleiner Perkins led the round, with participation from reality TV mogul Kris Jenner, model Hailey Bieber, billionaire Fanatics CEO Michael Rubin, Spanx founder Sara Blakely, and former Meta COO Sheryl Sandberg.
'I got my start in e-commerce, so I've always believed in the power of technology to transform how people shop online,' Rubin said in a statement. 'What excites me about Phia is how Phoebe and Sophia are bringing real innovation to the space by making shopping smarter and using technology to unlock a better experience for everyone.'
But the most striking aspect isn't the star-studded investor list - it's how quickly it all came together. The duo didn't even initiate the fundraising process. Soma Capital cold-messaged Kianni on LinkedIn after hearing about the product, ultimately providing one of the first institutional checks and introducing them to Kleiner Perkins.
'From there, they did end up introducing us to a ton of incredible people,' Kianni explained. 'We ended up both cold outreaching and then also getting other people to connect with us.'
The founders' approach breaks conventional startup wisdom. Instead of stealth mode, they've embraced radical transparency through their podcast 'The Burnouts,' launched simultaneously with Phia in April. The show has garnered nearly 500,000 Instagram followers and 10 million views across social platforms.
'We've taken a very digital-first approach to pretty much everything,' Kianni said. 'I think it's been part of the reason why we've seen such rapid traction.'
This transparency extends to their hiring practices - they recruit talent through social media and openly discuss company experiments, asking followers to direct message feedback. They even use ChatGPT to help craft viral marketing campaigns.
Kianni brings her own impressive network to the table. The 23-year-old founded the nonprofit Climate Cardinals, which translates climate information into different languages, became one of the youngest UN advisors ever, and appeared on the BBC's 100 Women list.
The Phia journey started with a buggy Chrome extension for finding second-hand fashion alternatives. User feedback quickly revealed their peers preferred mobile shopping and instant price comparisons over sustainability features.
'We should have known this honestly from our own behavior,' Gates admitted. 'The girl who's obsessively shopping and scrolling all the time is often doing it on her phone; laptop more when she's working, but the phone is key.'
The pivot paid off. With just 12 employees, Phia now searches across hundreds of millions of fashion items, creating what Gates envisions as a personalized shopping agent that could eventually sync with calendars to recommend optimal buying, selling, and keeping decisions.
This funding round represents more than capital - it's validation of a new fundraising playbook where social media presence, network effects, and radical transparency can compress traditional timelines. While most startups spend months courting investors, Gates and Kianni leveraged existing relationships and digital-first strategies to close their round in less than a month.
Gates and Kianni's lightning-fast funding success signals a fundamental shift in how Gen Z founders approach startup building. By combining powerful personal networks with radical transparency and social media-first strategies, they've compressed traditional fundraising timelines while building genuine user engagement. As fashion tech continues to evolve with AI integration, Phia's approach of open-sourcing their journey while scaling rapidly could become the new blueprint for consumer startup success.
