AI startup Giga has raised $61 million in a Series A round led by Redpoint Ventures, with participation from Y Combinator and Nexus Venture Partners.
The funding will be deployed for Giga’s technical team to accelerate go-to-market motion and scale deployments with the world’s largest enterprises.
Founded by IIT Kharagpur graduates and Forbes 30 Under 30 honorees Varun Vummadi (CEO) and Esha Manideep (CTO), Giga enables companies to deploy emotionally intelligent agents that can reason, act, and resolve issues — all in real time.
“What excites me most about Giga is that it’s not just building a best-in-class support bot—it’s that the team is building a foundational AI infrastructure layer for customer voice,” said Satish Dharmaraj, Managing Director at Redpoint Ventures. “This is one of our largest early stage investments to date because we believe deeply in both the strength of the product to reshape the world of customer support and the pace of execution from the Giga team.”
Abhishek Sharma, Managing Director, Nexus Venture Partners, added, “Giga is leading a paradigm shift in enterprise support with AI. Their category‑leading platform helps the biggest enterprises in the world to achiecompanies move from human and outsourced support to scalable, software‑driven AI—boosting efficiency, quality, and compliance. Varun, Esha, and the team are building one of the most transformational AI companies of our time, and it’s been a privilege for Nexus to be part of their journey since the early days.”
The firm’s platform is designed for high-compliance industries like e-commerce, financial services, healthcare, and telecommunications. Giga’s voice systems also handle millions of customer calls every month for large-scale enterprises, according to the company.
Some of the firms using Giga’s services include Postman, DoorDash, and trading platform Capital.com.
“Organizations globally spend billions on call centers every year and yet the customer experience is still broken. ” said Varun Vummadi, co-founder and CEO. “We built Giga to change that. For the first time ever, machines are capable of understanding the nuances of customer voices and holding conversations with them, fundamentally changing the way the world interacts with devices.”
Aniket Kamthe of Nexus Venture Partners said, “We’re thrilled to be working with Giga at this inflection point for AI-powered customer experiences. They’re setting new standards for deploying AI reliably at scale across complex enterprise environments.”
Designed for high-compliance industries like ecommerce, financial services, healthcare, and telecommunications, Giga’s agents use retrieval-augmented generation and contextual reasoning to deliver policy-safe, emotionally intelligent conversations, without sacrificing speed or accuracy.
Giga’s voice systems already handle millions of customer calls every month for large-scale enterprises, dramatically reducing wait times.
At DoorDash, Giga’s deployment improved resolution speed, reduced escalations, and enhanced operational efficiency across teams.
“At DoorDash, we operate at a massive scale across services, platforms, and languages,” said DoorDash co-founder Andy Fang. “Giga leveraged usage data to deliver measurable improvements, including fewer escalations, faster resolution paths, and more efficient workflows across our teams. As we continue to grow across more than 40 countries and serve nearly 50 million people each month, partnerships like this are critical to delivering better outcomes for consumers on a global scale.”
