Corelayer

Corelayer, formerly known as Sevvy, is an early-stage enterprise software company developing an artificial intelligence-powered on-call engineering platform designed specifically for data-heavy, highly regulated industries. The platform continuously monitors system logs, performance metrics, and underlying data to automatically debug complex production issues and suggest technical fixes within minutes. To accommodate the strict compliance and privacy requirements of the finance, healthcare, and insurance sectors, the system provides localized on-premises deployments alongside hardware-backed secure inference environments that safely utilize sensitive production data as context. Operating with a two-person employee headcount, the startup is currently backed by Y Combinator as a participating member of its Winter 2026 accelerator batch. Corelayer was founded by Mitch and Shipra, who previously collaborated on building large-scale data infrastructure systems capable of processing hundreds of billions of rows daily during their tenure at Goldman Sachs.
