Kai Tech Stack

Agentic AI platform automating enterprise security workflows at machine speed

Computer and Network Security San Jose, California 11–50 employees Privately Held

Kai builds an agentic AI security platform using vLLM, Triton, Ray, and vector databases (Milvus, Pinecone, Weaviate) to replace fragmented human-speed security workflows. The tech stack reveals a company prioritizing LLM inference optimization and real-time ML—vLLM and Triton are inference engines, Ray handles distributed compute, and the vector DB mix suggests heavy embedding-based reasoning. Hiring velocity is accelerating across engineering (7 roles), sales (6), and data (3), with two-thirds of open positions at senior or manager level, indicating a push to scale AI-driven product and go-to-market simultaneously.

About Kai

Kai is a privately held AI security company based in San Jose building an agentic platform that automates security operations at machine speed rather than human pace. The platform ingests security data via scalable pipelines (Apache Spark, Delta Lake, Databricks), reasons over it using LLM-based agents, and executes security tasks autonomously. The company serves Fortune 500 enterprises and is addressing persistent pain points in the security industry: fragmented workflows across tools, human-speed bottlenecks, and silo-driven tooling. The founding team includes creators of prior security category leaders, bringing domain credibility to the ambitious goal of rebuilding cybersecurity around agentic AI.
