Varun’s Journey: From IIT to AI Agents Powering Customer Support
Varun grew up in Andhra Pradesh, India, the son of government teachers who pushed him toward engineering or medicine. He attended IIT, where his early college years were marked by partying before he refocused on large‑language‑model research. A stint at Stanford deepened his expertise in transformers, and he earned a $550 k job offer from a New York quant firm, which he turned down. He also competed on Kaggle, winning roughly $50 k.
The Y Combinator Experience
Varun applied to Y Combinator with a co‑founder on an edtech concept. During the interview, YC partner Hajj rejected the idea and urged a pivot. Acting on that advice, Varun shifted to fine‑tuning LLMs to cut costs and latency, a move that secured a $4 million seed round based on open‑source model benchmarks.
Building GigaML
The fine‑tuned models found their strongest use cases in customer support and coding automation. Early contracts with Zepto and DoorDash validated the approach; GigaML won the DoorDash deal with a team of eight against a 400‑person competitor. The YC network helped establish enterprise trust, and the company now focuses on an “AI forward‑deployed engineer” that automates configuration and policy updates across Slack and Google Meet.
Business and Hiring Philosophy
Varun rejects the notion that founders need a traditional business background. He emphasizes finding the right Ideal Customer Profile and proving product value before scaling sales. The internal mantra—“Automate, automate, automate”—has shrunk the engineering team to 6‑7 times fewer members than a comparable non‑AI shop. Hiring prioritizes “spikiness” and deep technical skill, and interviews feature “vibe coding” to assess candidates’ ability to write code without AI assistance.
Mechanisms Behind the AI Agents
Traditional IVR and chatbot systems achieve only 10‑15 % support deflection. GigaML’s AI agents iterate on markdown policy files, directly influencing KPIs such as resolution rate and CSAT, and currently reach 60‑70 % deflection with a target of 90‑95 % for top customers. The AI forward‑deployed engineer joins communication channels, takes notes, and automatically configures dashboards or policy changes, turning enterprise deployments into high‑leverage, low‑overhead operations.
Takeaways
- Varun rejected a $550 k quant job, pursued LLM research, and founded GigaML after early successes on Kaggle and at Stanford.
- Following Y Combinator’s feedback, he pivoted from edtech to fine‑tuning LLMs, raising a $4 million seed round to build AI agents.
- GigaML’s agents have lifted customer‑support deflection from the industry norm of 10‑15 % to 60‑70 %, aiming for 90‑95 % with clients like DoorDash and Zepto.
- Using AI coding agents, GigaML operates with an engineering team 6‑7 times smaller than a comparable non‑AI shop, living by the mantra “automate, automate, automate.”
- Varun’s “burn the boats” mindset drives a product‑first strategy, hiring for technical depth and proving value before expanding sales or staff.
Frequently Asked Questions
How does GigaML achieve higher support deflection rates compared to traditional chatbots?
GigaML’s AI agents replace IVR and basic chatbots by iterating on markdown policy files that directly influence KPIs such as resolution rate and CSAT, delivering human‑like, real‑time answers. This approach lifts deflection from the typical 10‑15 % to 60‑70 % and targets 90‑95 % for key customers.
What is an “AI forward‑deployed engineer” as described by Varun?
An AI forward‑deployed engineer is a system that joins Slack or Google Meet sessions, records discussion, and automatically updates dashboards or policy configurations to improve performance metrics. It acts as a virtual engineer that handles enterprise configuration and policy updates without human intervention.
