Coco Wallet
Coco Wallet (YC S19) is a global dollar account powered by stablecoins. Founded by Venezuelan entrepreneur Kevin Charles and his co-founders, it lets Latin American migrants and their families send, spend, save, and earn in digital dollars from a mobile app - combining the simplicity of a neobank like Nubank or Revolut with the freedom of self-custodial Web3, so people can access stable, borderless money without a traditional bank.
Nick Shelly
Nick Shelly is the co-founder and CEO of Apero Health, a Y Combinator-backed (S19) medical-billing and revenue-cycle company in San Francisco that helps healthcare practices get paid faster and gives patients clearer bills. Before software, he was a computer scientist with an unusually wide runway: a U.S. Air Force Academy graduate, a Rhodes Scholar at Oxford, a Stanford CS researcher in computer networking, and an engineer at Apple, Nicira, and Forward Networks. He turned that systems-and-networks training toward one of the least glamorous, most broken corners of American life - the medical bill - and built Apero with co-founder Jacinda Shelly to fix the plumbing behind it.
Courier
Courier is a San Francisco notification infrastructure platform that lets developers add multi-channel messaging - email, SMS, push, in-app, Slack and more - to their apps through a single API and a drag-and-drop designer. Often described as 'Stripe for notifications,' it routes messages intelligently across channels so engineering teams stop rebuilding notification systems from scratch. Founded in 2019 (YC S19), Courier raised a $35M Series B led by GV in 2022 and powers notifications for companies like New Relic, LaunchDarkly, Lattice, Vanta and Contentful.
Mark Murphy
Mark Murphy is the co-founder and CEO of Banner (withbanner.com), a New York proptech building the capital-expenditure operating system for commercial real estate. After years in real estate finance at Goldman Sachs and RBC Capital Markets, he watched institutional owners run billion-dollar capital projects on spreadsheets, email threads, and disconnected tools, and started Banner in 2019 with college friend Kunal Chaudhary to replace that mess with one platform. Backed by Y Combinator (S19), Blackstone, Fifth Wall, Pruven Capital and Basis Set Ventures, Banner raised a $10M Series A in October 2023 and now oversees more than $10 billion in capital spend for operators like Starwood Capital, LivCor, Morgan Properties and Industrious.
Samarth Sindhi
Samarth Sindhi is the founder and CEO of Good Health Company (GHC), the Hyderabad-based direct-to-consumer wellness platform behind Mars by GHC (for men) and Saturn by GHC (for women). A Brown University mechanical engineer and Y Combinator S19 alum, he first built Digi-Prex, a subscription pharmacy for chronic care, before launching GHC in January 2021 to tackle topics men rarely talk about out loud. GHC has raised about $15.2 million, including a $10 million Series A led by Left Lane Capital in October 2022, and Sindhi has been named to Forbes 30 Under 30.
