/ @ycombinator -backed startups transform crypto payments Three YC alumni are reshaping global payments: @RequestNetwork (W17), @Cypher_HQ_ (W22), and @blindpay (W25). Request Network, a 2017 decentralized payment pioneer, reached $41M monthly volume in early 2025. Cypher ($4.3M seed) serves 100K+ users across 120 countries with stablecoin payment cards. Peak monthly volume hit $23M, now steady at $20M. BlindPay ($3.3M seed) builds global payment infrastructure on stablecoins. Mid-2025 peak reached $103M monthly volume. The stats shows exponential growth since 2024 — a massive shift from traditional rails to on-chain alternatives. YC's consistent bet on crypto payment infrastructure proves the thesis: stablecoins are the future of global commerce.
