Cortex

Cortex builds an AI-powered Internal Developer Portal for engineering organisations running large microservices estates. The platform serves as a central source of truth for services, cataloging thousands of them automatically and scoring each against production-readiness criteria. Technical work spans AI, service cataloging, reliability engineering and automated workflows, with the stated aim of replacing tribal knowledge with institutional knowledge that teams can act on.

The product drives action through automated workflows and connects data across the engineering toolchain to enforce reliability standards. Reported outcomes include a 30% reduction in incidents, a 50% cut in mean time to resolution (MTTR), and engineer onboarding measured in hours rather than weeks. Customers include Canva, Grammarly and Skyscanner.

The company was founded by engineers who encountered these problems at Uber and Twilio, and concentrates on reducing on-call pain and overnight incidents so that developers can focus on work that advances the business. Cortex also supports the safe rollout of AI coding assistants within engineering organisations.
