Kairos

Kairos, built by Y Combinator-backed Janus AI, Inc. under the product's current brand (formerly Janus), develops specialized AI systems for enterprise use in regulated industries, transforming frontier AI models into reliable, private, and sovereign solutions that operate within client environments. The platform is built around three core capabilities: Reliability, achieving 99%-plus accuracy by learning an organization's own policies rather than relying on generic models; Privacy, deploying entirely within client environments so data never leaves and stays proprietary; and Sovereignty, creating customized AI foundations that clients own outright. The company recently launched Telos, described as a learning layer for long-horizon AI workflows. Pricing is not disclosed publicly; interested organizations are directed to book a demo for details.
