US YC S23 at-home 30-minute cancer screening for prostate, bladder, and ovarian cancers; $846K Mayo Clinic/TQ Ventures/YC-backed with synthetic biology + computer vision from Oxford Rhodes Scholar founders competing with GRAIL for accessible early cancer detection.
Cleancard is a United States-based at-home cancer screening company — backed by Y Combinator (S23) with $846,000 in total funding from Mayo Clinic Platform, TQ Ventures, Urban Innovation Fund, Y Combinator, and the Creative Destruction Lab — developing a 30-minute at-home diagnostic platform that combines synthetic biology, machine learning, and computer vision to detect multiple cancer biomarkers from a single patient sample for prostate, bladder, and ovarian cancers. Founded by Luca Springer and Thomas Carroll (both Rhodes Scholars from Oxford), Cleancard targets the massive unmet need for accessible, affordable cancer screening outside of clinical settings — the 30-minute result time and home-based format enabling screening at the frequency and convenience required for early cancer detection programs.
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.
