IIT Startup Giga Raises $61M to Redefine Voice AI in Customer Care

San Francisco-based startup Giga has secured $61 million in a Series-A funding round led by Redpoint Ventures, with participation from Y Combinator and Nexus Venture Partners, to scale its AI-powered voice customer-care platform. Founded in 2023 by IIT Kharagpur alumni Varun Vummadi (CEO) and Esha Manideep (CTO), the company aims to automate thousands of enterprise voice-based support workflows with minimal human intervention. 

Giga’s technology allows enterprises to upload existing transcripts, knowledge bases and policy documents—which the system uses to build AI agents capable of handling live voice conversations across languages and channels. The startup already claims to process millions of customer-interactions every month in sectors such as e-commerce, finance, healthcare and telecom. 

With the fresh capital, Giga plans to expand its engineering team, accelerate its go-to-market play and deepen enterprise deployments globally. The venture signals heightened investor interest in “agentic AI” platforms that move beyond chatbots and into natural-voice interaction. 

The move also comes amid a broader industry shift: businesses are increasingly replacing human-operated contact centres with AI-driven support models to reduce cost and improve resolution speed. Giga’s founders highlight that their system improves key metrics like resolution time, escalate rates and customer satisfaction. 

However, the space is highly competitive. Established players and emerging startups alike are racing to crack voice-AI for customer service—a domain that demands not only cutting-edge language models, but also enterprise-grade reliability, multilingual support and regulatory compliance. Giga will need to deliver on scalability and differentiated outcomes to maintain its edge.

In essence, Giga’s $61 million raise marks a bell-wether moment for the enterprise voice-automation sector: the integration of deep AI, voice interaction, and enterprise workflow automation is becoming a serious battleground. For Indian-origin founders making global gams, this round underscores both the opportunity and the challenge of transforming an age-old function—customer care—through AI.
