Kognitos is transforming the trillion-dollar hyper-automation market. Our mission is to redefine how software is built, operated, and evolved—using a multi-agent automation platform that enables systems to reason, plan, and execute deterministically.

We elevate debugging to English, eliminating the brittleness of traditional programming languages that break under real-world complexity. At Kognitos, we’re building “HAL”—but the friendly, helpful kind—creating AI systems grounded in safety, transparency, and real business impact.

Our team includes engineers from Google, Microsoft, Meta, Amazon, and top startups, with academic roots at IIT, Stanford, CMU, UC Berkeley, Georgia Tech, and more.

We have offices in Mountain View, CA and Bangalore, India, and we collaborate closely across regions.
