Mad Idea of the Day

NAQLI CALL!! 📵

INDIA RECEIVES 2 BILLION SPAM AND SCAM CALLS EVERY DAY. YOU HAVE RECEIVED THE TRAI CALL. YOUR MOTHER HAS RECEIVED THE ELECTRICITY CUT CALL. YOUR FATHER HAS RECEIVED THE "YOUR SON IS IN TROUBLE" CALL. INDIA LOSES ₹11,000 CR ANNUALLY TO PHONE FRAUD. NOBODY BUILT THE AI THAT FIGHTS BACK.

The Challenge: India is the world's most spam-called country. TRAI data confirms 2-3 billion spam and scam calls are made daily across Indian networks. The scripts are sophisticated and India-specific: "Main TRAI se bol raha hoon, aapka number illegal activities mein use hua hai, 2 ghante mein block ho jaayega" — the fake TRAI call. "Aapka bijli connection aaj raat 9 baje kata jaayega, abhi verify karein" — the electricity scam. "Sir, aapke bete ko accident hua hai, abhi 50,000 transfer karo" — the family emergency fraud. Voice cloning technology now lets criminals clone your son's voice from his YouTube videos and call you in his voice saying he's in danger. The MHA reported ₹11,333 Cr lost to cybercrime in 2023 — a number that has grown every year since. Truecaller identifies known spam numbers from a database, but it cannot score an unknown scam number in real-time, cannot detect voice cloning, cannot engage the fraudster to waste their time, and cannot auto-file a complaint with TRAI or NCMC. The scammer calls you 50 times a day because it costs nothing and the success rate is high enough. Nobody made it expensive to try.

The Solution: Naqli Call — India's AI-powered scam call detection and counter-attack platform 📵. When your phone rings, Naqli Call's AI analyzes three things in under two seconds before you pick up: the number's history (flagged by community, telecom data, or pattern recognition), the call's timing and frequency signature (scammers call during business hours in high volumes from shifting numbers), and for answered calls, the voice pattern against India's known scam scripts in 12 languages. Your screen shows a Naqli Score before the call connects: 91% scam probability means you don't pick up. When a high-probability scam call comes in, press one button — the Naqli Bot answers in your place. It speaks naturally in Hindi, says "Haan, main bol raha hoon, bataiye," and keeps the scammer engaged — recording the full conversation while wasting 8-12 minutes of their time per call. Each call that the bot handles is automatically logged, analyzed for new script patterns, and — if confirmed as fraud — filed as a complaint to TRAI's DND registry and the NCMC cybercrime portal with the recording as evidence. For elderly parents, family members activate Elder Shield: every call above 60% Naqli Score on a parent's phone triggers a real-time WhatsApp alert to the family group before the call connects.

Business Model: 💰

  • Free: Basic Naqli Score overlay, community blacklist, elder shield (1 number)

  • ₹49/month: AI real-time scoring, bot trap, TRAI complaint auto-filing, 5-number family plan

  • B2B bank API: SBI, HDFC, ICICI pay per-query to flag calls impersonating their institution's IVR number

  • Telco deal: Airtel, Jio, Vi pay for bulk scam signal data to protect their subscriber base

Exit Strategy: 🚀 5 crore active users by FY30, ₹400 Cr ARR. Natural acquirers: Truecaller (wants the India-specific AI scam layer they don't have), Airtel or Jio (building subscriber protection as a network feature), or an international cybersecurity company (NortonLifeLock, Palo Alto Networks) expanding into India's mass consumer market.

Mad Hack

The Wrong Start: In 1996, Sanjeev Bikhchandani was working a comfortable market research job in Delhi. He picked up a classified jobs magazine called "Situation Vacant" — thick, printed, sold at railway stations for ₹10. He stared at it and had a single thought: when the internet reaches India, nobody will buy this. Jobs will move online. He borrowed ₹2 lakh, quit his job, and started building a jobs website from his brother-in-law's servant quarters in Noida. His wife became the family's sole earner. Internet penetration in India in 1997 was less than 0.1%. He spent the next three years building a database of CVs and job listings for a market that barely existed.

The Pivot: Sanjeev didn't pivot the product. He pivoted his relationship with time. While his peers waited for the market to arrive before building for it, he built for a market that hadn't arrived yet. When India's IT boom exploded in 1999-2000 and cybercafes multiplied across every city, Naukri.com was the only platform with three years of indexed CVs and job listings already in the database. The boom didn't create Naukri's success. Sanjeev's patience did. He had already done the work.

The Payoff: Naukri.com became India's largest job portal. Info Edge listed on BSE and NSE in 2006 — the first internet company to list in India. Then Sanjeev became India's most important startup investor: he invested ₹4.5 Cr in Zomato (then called Foodiebay) in 2010 — which became ₹7,000+ Cr at Zomato's IPO. He invested in Policybazaar (PB Fintech) — listed at ₹40,000 Cr. He invested in Shiprocket. The man who built the first Indian internet company then funded the next generation of Indian internet companies.

🎯 The Builder Lesson: The best time to build a market is before it exists. The worst investors are those who only write cheques after the market is obvious. Sanjeev did both — built early, invested early, and let time do the rest.
