AI firm Giga raises $61 million, will scale AI agents for enterprise customer support

Burry’s latest 13F filing reveals bearish bets on Nvidia and Palantir, shaking AI-heavy tech stocks and reigniting fears of another market bubble.

Artificial intelligence (AI) support automation startup Giga has raised $61 million in a Series A round led by Redpoint Ventures, with participation from Y Combinator and Nexus Venture Partners, as large enterprises accelerate the shift from outsourced call centres to AI-driven support systems.

The company plans to use the capital to expand its technical team, speed up go-to-market efforts, and scale deployments with global customers, it said in a release on November 6.

The investment also shows growing competition in enterprise-grade support automation, where several large language model (LLM) companies and customer engagement platforms are attempting to build AI-native workflows.

Founded by IIT-Kharagpur graduates Varun Vummadi and Esha Manideep, Giga is used in high-volume industries including ecommerce, finance, healthcare, and telecommunications.

Unlike many support automation tools that rely on scripted flows, Giga ingests an enterprise’s existing knowledge base and uses retrieval-augmented generation (RAG) along with contextual memory to generate high-accuracy response systems.

RAG is an approach where a model first retrieves relevant information from a knowledge source and then uses that context to generate more accurate responses.

The company says its agents can handle complex user conversations, multilingual workflows, and emotional tone detection.

“What excites me most about Giga is that the team is not just building a better support bot. They are building foundational AI infrastructure for customer voice,” said Satish Dharmaraj, Managing Director at Redpoint Ventures. “This is one of our largest early-stage investments because we believe the product has the potential to reshape enterprise support.”

Nexus Venture Partners, an early backer of the company, highlighted the shift among global enterprises from human-led service desks to software-driven conversational support.

Giga’s deployment with DoorDash, for instance, reduced call escalations and improved resolution speed across its global support operations. “As we continue to grow across more than 40 countries and serve nearly 50 million people each month, partnerships like this are critical,” said DoorDash co-founder Andy Fang.

CEO Varun Vummadi said Giga was built because machines are now capable of understanding customer voice with nuance.
