An engineer who learned
to sell. Then to keep.
Then to grow.

Fifteen years. Three industries. One relentless obsession with revenue that compounds.

I began in engineering — systems thinking, infrastructure, the satisfaction of things that hold under load. But I discovered early that the most interesting problems weren't technical. They were human.

How do you get someone to trust you enough to sign? How do you make them stay? How do you turn a customer into a champion? Those questions pulled me from hardware floors in Chennai into the world of sales — and never let go.

"The real revenue isn't in the signature — it's in the renewal, the expansion, the advocate who brings you three more logos."

— On the transition from sales to customer success

Ten years in sales and business development across IT infrastructure, EdTech, and SaaS — from cold-calling to closing enterprise deals in New York. Then the pull toward Customer Success: realising that acquisition without retention is a leaking bucket.

At Chargebee, I lived the $1M→$100M journey — from individual contributor to managing 20+ people across the US, Amsterdam, and India. I took a fragmented CS org and turned it into the highest-performing region globally, 140% NRR, a full President's Club sweep for the entire team.

Now at Murf.ai, I'm doing the $10M→$100M run again — but this time AI-first. Built the CS and AM functions from scratch. Designed Clay and Make automations that give my team superpowers. NRR grew from 114% to 128%.
