Bengaluru Voice AI Startup SuperBryn Raises $1.2 Mn to Fix Why Most Voice Agents Fail in the Real World

Bengaluru-based voice AI startup SuperBryn has raised $1.2 million in pre-seed funding in a round led by Kalaari Capital’s CXXO initiative, which backs women-founded companies.

The round also saw participation from prominent angel investors, including Rikant Pitti, co-founder of EaseMyTrip; Arjun Pillai, founder of Docket AI; Sharath Keshava Narayanan, founder of Sanas AI; Harish Manian, CEO of BMH Group; and actor Nivin Pauly.

SuperBryn is building a reliability framework designed to help enterprises deploy voice AI agents at scale. The platform focuses on automated stress testing, continuous production monitoring, and intelligent self-learning to ensure voice agents perform reliably in real-world conditions.

The company claims this approach enables businesses to move from pilot deployments to full production 20 times faster and at one-tenth the cost.

The startup’s journey has been marked by multiple pivots. “We pivoted almost five times. We had no idea which direction to take. We tried, we failed, we rebuilt, we scaled up, we scaled way down,” said Neethu Mariam Joy, co-founder and CTO of SuperBryn, in a LinkedIn post.

The breakthrough came when a client asked the company to build a voice agent as a side project. That engagement exposed deeper challenges around maintaining and improving voice agents in production environments, which later became SuperBryn’s core focus.

“We realised that businesses have many tools to launch voice agents, but very few to maintain, monitor, and improve them in production,” Nikkitha Shanker, co-founder and CEO of SuperBryn, told ET.

According to the startup, more than 70% of voice AI pilots fail due to reliability issues. Using SuperBryn’s platform, clients have reportedly improved issue resolution rates from below 40% to over 80% within 60 days, The Economic Times reported.
