Virtual Try-Ons and Size Perfection: Kopia's Vision for the Future of Online Apparel

Kopia is a trailblazing startup, founded in 2023, that is set to revolutionize the online shopping experience through the power of artificial intelligence (AI). Based in San Francisco and backed by group partner Gustaf Alstromer, Kopia is the brainchild of Calvin Chen and Aadi, two innovative college dropouts with a deep background in e-commerce and generative AI. The company aims to make online shopping a more personalized, engaging, and efficient experience by enabling users to virtually try on clothing and receive accurate size recommendations.

How Did Kopia Begin?

Calvin Chen, one of the active founders, brings a wealth of experience to Kopia. He previously founded two startups in the e-commerce and apparel software sectors. Impressively, while still in high school, Calvin built a software startup in e-commerce that achieved an annual recurring revenue (ARR) of $1.5 million and was acquired for $9 million. He also launched a Rent The Runway-style service for men, which attracted 3,000 monthly active users (MAUs) and generated $240,000 in ARR. His co-founder, Aadi, conducted natural language processing (NLP) research for Verizon in high school and developed multiple generative AI products for a Y Combinator-backed startup while studying computer science at Stanford. Their combined expertise and passion for innovation led to the creation of Kopia.

What Problem is Kopia Solving?

Online shopping, particularly for apparel, presents significant challenges for both consumers and brands. Consumers often struggle to visualize how clothing items will look on them, especially when the models used in product images do not resemble their own body types. Additionally, determining the correct size and fit is notoriously difficult, leading to frequent returns. For brands, these issues result in low conversion rates—typically between 0.5% and 1.5%—and high return rates, with over 60% of returns being due to fit discrepancies. This translates to lower sales and reduced profitability for e-commerce businesses.

What is Kopia’s Solution?

Kopia addresses these challenges head-on with its innovative AI-driven virtual try-on experience. By integrating seamlessly into any e-commerce platform, Kopia allows customers to visualize themselves wearing different clothing items and receive precise size recommendations with just a few simple steps. Users answer a few questions about their body type and upload a single selfie or headshot. This information enables Kopia’s AI to generate realistic images of the user in various outfits, making it easier to find the perfect fit and style without the need for multiple returns.

How Does Kopia’s Technology Work?

Kopia’s technology leverages the latest advancements in generative AI, particularly diffusion models, to create a highly realistic virtual try-on experience. Diffusion models are a type of machine learning model that can generate detailed and accurate images based on input data. In Kopia’s case, this means producing lifelike images of users in different clothing items. Once a user inputs their body type details and a selfie, the AI processes this information to create a personalized shopping experience across any brand that partners with Kopia. This not only enhances the shopping experience for consumers but also increases conversion rates and reduces return rates for brands.

Who Are the Founders Behind Kopia?

Calvin Chen and Aadi are the dynamic duo behind Kopia. Calvin’s entrepreneurial journey began in high school when he bootstrapped his first e-commerce software startup to a successful acquisition. His subsequent venture, a luxury apparel rental platform, further solidified his expertise in the e-commerce sector. Aadi, on the other hand, has a background in NLP research and generative AI product development. His experience includes working on AI projects for a Y Combinator-backed startup and building the leading diffusion model for virtual try-on at Kopia within just three months. Together, they bring a unique blend of technical skill and entrepreneurial spirit to Kopia.

What is the Market Opportunity for Kopia?

The market opportunity for Kopia is vast, particularly in the $250 billion U.S. e-commerce apparel market. Virtual try-on technology represents a significant shift in the online shopping paradigm, offering a more interactive and personalized experience for consumers.

Kopia’s early success in developing the leading diffusion model for virtual try-on and attracting thousands of users within a few months underscores the significant market potential and the readiness of consumers and brands to embrace this innovation.

How Will Kopia Change Online Shopping?
