Agentcard is a fintech startup building payment infrastructure that lets AI agents pay for things online autonomously, issuing budget-capped, single-use Visa-backed debit cards through a wallet and purchase API. It is part of Y Combinator's Summer 2026 batch, backed by YC, the Pioneer Fund, and angel investors including Paul Graham and Tobi Lutke. Co-founder and CEO Karen Serfaty previously led Atlas, an expense-card company acquired by Remote.com; co-founder and CTO Felipe Abello is a second-time YC founder (Nara, W22) and was Rappi's first employee.
