Quartile is an advertising technology company headquartered in New York that provides AI-powered advertising optimization for Amazon sellers and brands, automating the management of Sponsored Products, Sponsored Brands, Sponsored Display, and Amazon DSP campaigns through a proprietary six-stage optimization algorithm that the company has filed patents on. Founded in 2019, Quartile targets brands and professional Amazon sellers that are serious enough about Amazon advertising to need algorithmic optimization beyond what Amazon's native campaign bidding provides, but may lack the internal advertising operations expertise or bandwidth to manually optimize the continuous bid management, keyword expansion, and negative keyword maintenance that high-performing Amazon advertising programs require at scale.
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.
