We're building the IDE for AI agents — making it possible for engineers to compose, test, and deploy production-grade agentic workflows without wrestling with infrastructure.
Cardinal was born from a simple observation: building AI agents is hard. Not because the technology isn't ready, but because the tooling is fragmented. Engineers spend weeks wiring together LLMs, data sources, approval flows, and deployment infrastructure before they can ship anything to production.
We spent years at Netflix building the platforms that powered the company's engineering teams — observability systems processing petabytes of data, real-time data pipelines, centralized logging, and developer tools used by thousands of engineers daily. We saw firsthand how great tooling transforms what teams can accomplish.
With Cardinal, we're bringing that same philosophy to AI agents. We believe the next wave of automation won't come from data scientists tuning models — it'll come from engineers building agents that solve real problems. Our job is to make that as simple as writing a few lines of code.

Ruchir was the lead engineer on Netflix's Observability Platform Team, where he spent 7 years building petabyte-scale systems serving thousands of Netflix engineers. He architected real-time monitoring and alerting infrastructure that kept Netflix running smoothly for hundreds of millions of users worldwide.
We're always looking for talented engineers, designers, and builders who want to shape the future of AI tooling.
