Atman Kar is the Co-Founder and CTO of Refortifai (YC P26), a cutting-edge runtime security platform purpose-built to protect AI agents from real-time threats and adversarial attacks.

Atman studied Electrical Engineering at BITS Pilani, Goa, developing deep expertise in semiconductors and signal processing, before working as an RTL Digital Design Engineer at Texas Instruments.

With a strong foundation in low-level systems engineering and hardware design, Atman brings a unique technical perspective to AI security, bridging the gap between silicon-level thinking and modern agentic software.

At Refortifai, Atman leads all technical architecture, building a security agent that intercepts tool calls, enforces governance policies, and blocks attacks such as prompt injection, memory poisoning, and privilege escalation in real time.

Refortifai, backed by Y Combinator in the P26 batch, is addressing one of the most critical gaps in the agentic AI era, providing enterprises with a lightweight, integrable security layer that sits on top of existing agent infrastructure.
