The reality

Most founders spend months
building something nobody wants.

Customer interviews take weeks. Surveys get ignored. By the time you know, you've already burned your runway.

The old way
  • ✗Customer interviews: 4–6 weeks
  • ✗Surveys: low response rate
  • ✗Market research: ₹50,000+
  • ✗Feedback bias: people are polite
  • ✗You learn after you've built it
HallowTwin

We nearly launched a ₹15 lakh product that 78% of simulated customers wouldn't buy. HallowTwin told us in 90 seconds. We pivoted the pricing, re-ran, and shipped something people actually wanted.
