The Problem Your Project Solves The Real Problem

Millions of people earn good incomes but fail to build wealth. Why?

They make impulsive big purchases (iPhones, laptops, cars) They don't understand the real cost (just focus on monthly EMI) They realize too late that purchase destroyed savings/delayed goals By then, it's too late—they're locked into 12-24 month EMI Pain Points Users Face

"I want to buy iPhone 15 but don't know if I can afford it"

No tool tells them the full impact Budget apps just track past spending (not future impact) EMI calculators are generic (not personalized) Financial advisors cost ₹5,000+ per consultation

"I took an EMI for a car and now my emergency fund is gone"

Should have known this before buying No way to simulate impact beforehand Now stuck in debt spiral

"This purchase delayed my house goal by a year"

Didn't realize the opportunity cost No one showed them alternatives Regret is too late Market Gap

Existing solutions don't work:

YNAB, Mint: Track past spending (not future decisions) EMI calculators: Generic math (not personalized) Financial advisors: Expensive, hard to access Banks: Want you to take EMI (incentive mismatch)
