# Market Validation

I noted that the staff said “Sir if you pay by UPI you will get ₹100 off”.

I recorded that the Subway sandwich initially cost me ₹455.

I realized it took me a long time to understand that I need to sell first and build later.

I observed that the customer acquisition cost (CAC) to onboard on the Adani payment app is ₹100.

During a visit to the Subway outlet at Terminal 2, Mumbai Airport on 2026‑10‑13, I paid ₹455 for a sandwich. The staff offered a ₹100 discount for UPI payment, which required onboarding to the Adani app. After onboarding, the final charge was ₹355, confirming the effective discount and indicating a CAC of ₹100 for acquiring a new Adani app user in this context.

- Decision = Avoid branding as a low‑cost "rajma chawal" restaurant
- Observation = Faff & M were slower and arrived sooo early, then Instinct wave took away everything in a jiffy
- Reason = Would dilute intended positioning and brand appeal
- Reason = Market research suggests insufficient demand or cultural fit
- Reason = Prevents wasteful investment in locations or cuisines lacking proven demand
- Personal AI devices
- Smart AI IoT
- AI Food robot
- Robo Teleoperation
- Apps for robots -> plug and play
