Introduction
Tata Digital wants to grow monthly transacting users on Tata Pay UPI roughly tenfold, and NeuCoins on UPI payments are one of the strongest levers it has. But UPI earns almost nothing per transaction for most payments, so every NeuCoin given on UPI is a direct cost. In 2025, Tata Neu and its card partners tightened UPI rewards (for example, caps on NeuCoins earned through UPI on co-branded cards), and users noticed. The trade-off in this question: should Tata Neu keep UPI rewards generous to drive payments growth, or tighten them further to protect loyalty margins as Tata Digital works to narrow its losses?
I'll ask clarifying questions, identify the trade-off type, understand the product, form a hypothesis, define metrics, design an experiment, plan the analysis, set a decision framework and close with a recommendation.

Clarifying Questions (3 minutes)
- Why it matters: Sizes the stakes.
- Hypothetical answer: UPI accounts for about 25% of NeuCoins issued, at roughly ₹45 per transacting user per month.
- Why it matters: Rewards that grow MTU but not downstream value are wasteful.
- Hypothetical answer: Downstream value; MTU is a means to that end.
- Why it matters: If they never shop at Tata brands, rewards are buying low-value users.
- Hypothetical answer: Around 40% of UPI-heavy users also buy from at least one Tata brand monthly.
- Why it matters: Enables middle-ground options.
- Hypothetical answer: Yes, the rewards engine supports rules by segment, merchant category and instrument.
- Hypothetical answer: Yes, loyalty cost must fall by 15% year on year as a share of GMV.
