Culver City CA livestream shopping marketplace (private, $3.7B valuation); $775M+ raised ($260M Series E DST Global), largest US live auction for collectibles/trading cards/sneakers, 50,000+ shows/week competing with eBay Live.
Whatnot is a Culver City, California-based live auction and shopping platform — founded in 2019 by Grant LaFontaine (CEO) and Logan Head (COO, both Y Combinator-backed) — operating the largest livestream shopping marketplace in the United States where sellers host live video auction shows for collectibles, trading cards, vintage clothing, sneakers, anime merchandise, and other enthusiast categories, with buyers bidding in real time through a mobile app and web platform. The company has raised $775 million+ in total funding including a $260 million Series E led by DST Global in March 2024, reaching a $3.7 billion post-money valuation. Whatnot connects hundreds of thousands of verified sellers — ranging from casual collectors to professional resellers with dedicated Pokémon card, sports card, and sneaker inventory — with millions of buyers seeking authenticated collectibles and the entertainment experience of competitive live auction bidding. The platform hosts 50,000+ shows per week across categories including trading cards, vintage apparel, toys, anime figurines, concert memorabilia, and video games — creating a continuous live content ecosystem that generates the engagement density that traditional e-commerce platforms cannot match. The platform operates primarily in the United States but launched in Germany and the United Kingdom in 2023, establishing European market presence ahead of TikTok Shop's European expansion into the same live shopping category.
Global payments infrastructure founded by Patrick and John Collison (YC W10); $1.4T payments volume in 2024; $18B+ revenue; $106.7B valuation as of Sept 2025; powers everything from startups to Fortune 500 companies with developer-first API design.
Stripe is a global payments infrastructure company founded in 2010 by Irish brothers Patrick and John Collison, headquartered in San Francisco, California and Dublin, Ireland. Stripe was born from the insight that accepting payments online was unnecessarily complex for developers, and that a well-designed API could unlock an entire generation of internet businesses. The company went through Y Combinator's Winter 2010 batch and grew to become the defining payments infrastructure layer of the modern internet economy, processing payments for businesses in virtually every industry worldwide.\n\nStripe's platform provides payment processing, fraud prevention via Stripe Radar, subscription billing, revenue recognition, banking-as-a-service through Stripe Treasury, corporate card issuance, identity verification, and tax compliance tools. It serves a spectrum from early-stage startups to publicly traded enterprises including Amazon, Google, Salesforce, and Shopify. Stripe's developer-first philosophy — comprehensive documentation, SDKs in every major language, and a sandbox testing environment — created an ecosystem of millions of businesses built entirely on its infrastructure.\n\nStripe processed $1.4 trillion in total payment volume in 2024 and generates over $18 billion in annual revenue, with a valuation of $106.7 billion as of September 2025. The company has remained private longer than most comparably sized technology companies, giving it flexibility to invest in long-term product expansion. An April 2024 partnership with Apple Pay extended Stripe's reach further into mobile and in-store commerce. Stripe competes with Adyen, Braintree (PayPal), and Square, but its developer ecosystem depth and global infrastructure make it the default payments platform for a generation of technology companies.
