Hello, I am
DhairyaMehta
Built growth where no
playbook existed.
Five years. Zero templates. Systems built from scratch.
I've spent 5+ years figuring out why students from families earning ₹15,000/month pay ₹2/day for a subscription — and building the systems that make them stay.
At Testbook, I own the P&L of India's largest exam-prep subscription. More than doubled revenue in 3 years — not through bigger budgets, but through understanding the friction points, trust signals, and payment behaviours of tier 2 and 3 India users that most growth playbooks ignore.
I came from Electronics Engineering, not marketing. That wiring gives me one edge: I build the tool when the tool doesn't exist.

Key drivers:
