Your cold email to an investor should open with their own words.
Before writing to any investor, paste their 3 most recent LinkedIn posts into Claude and prompt: "What themes is this person clearly obsessed with right now? Write the first two lines of a cold email from a founder connecting their startup to these themes." Personalisation at this level takes 4 minutes and triples reply rates. The investor thinks: this person actually did their homework.

Mad Idea of the Day
JAGAH BAAZAR!! 🏢

INDIA'S TOP COMPANIES COLLECTIVELY PAY ₹800 CR EVERY MONTH FOR OFFICE SPACE THAT NOBODY SITS IN. TWO KILOMETRES AWAY, A 20-PERSON STARTUP IS PAYING ₹60,000 A MONTH FOR COWORKING AND SHARING A PRINTER WITH 40 STRANGERS. NOBODY BUILT THE PLATFORM CONNECTING THEM.
The Challenge: India's top six cities have over 25 crore sq ft of premium corporate office space. After four years of hybrid work stabilising, average utilisation across large corporate offices runs at 55-60%. That means 10+ crore sq ft of paid-for, premium, air-conditioned, high-speed-internet office space sits empty every Monday, every Friday, and for most companies, parts of every working week. Companies are locked into 5-10 year leases signed before 2020 — they cannot exit them, and they cannot legally sublet without navigating complex building management approvals and landlord permissions that have historically required months of paperwork. On the other side: India has 10 lakh+ recognised startups, most of which cannot afford a 5-year commercial lease but desperately need more than a hot-desk at a café. Premium coworking (WeWork, Awfis, Smartworks) charges ₹15,000-₹30,000 per seat per month. A 20-person startup in Bengaluru or Mumbai pays ₹4-6 lakh per month for managed coworking — for a space that is not theirs, in a building they do not control, next to 200 people they did not choose. The math is visible to anyone paying attention. The platform to solve it has not been built.
The Solution: Jagah Baazar — India's verified B2B corporate office space subletting marketplace 🏢. A company with excess capacity registers their space: available seats, conference rooms, or entire floors, with specific available days and times. Jagah Baazar handles all the complexity they'd otherwise avoid — a pre-built legal subletting agreement framework tested and approved with major building management companies, KYC verification for all listing tenants, access management integration with common building security systems (so a subletting startup employee can swipe in with a temporary digital access pass, not a paper visitors log), and landlord approval automation (where required). A startup searches by city, micromarket, seat count, budget, and days per week. They see verified listings with real photos, infrastructure details, and pricing — not a broker's WhatsApp message. They book by the week or month. Jagah Baazar's insurance product covers the listing company if the subletting startup causes damage. No long negotiation. No unknown visitor entering a corporate floor. No paperwork pile. Just a discovery layer, a legal wrapper, and a transaction — for office space that was going to cost the company money anyway.
Business Model: 💰
10% commission on every subletting transaction
₹5,000/month corporate lister subscription: unlimited listings, legal toolkit, access management dashboard, insurance coverage
₹20,000/month enterprise: companies with 5+ office locations get a centralised real estate monetisation dashboard and a dedicated Jagah Baazar account manager
B2B building management companies: ₹1 lakh/year API integration fee to make their buildings "Jagah Baazar Compatible"
Exit Strategy: 🚀 2,000 corporate listers + 12,000 startup/MSME tenants by FY30, ₹180 Cr ARR. Acquirers: WeWork India or Awfis (want supply inventory for their marketplace), CBRE or JLL India (commercial real estate services wanting a tech-led monetisation layer), or a large PropTech platform wanting to extend from residential to commercial.
Mad Trends

India's 9 crore gig workers are entering the social security system for the first time — and none of the financial products they need actually exist yet. 🛵
The Shift: For 15 years, India's gig economy grew without a safety net. Platform workers — Swiggy delivery executives, Ola drivers, Urban Company plumbers, Dunzo runners — were "partners," not employees, and therefore invisible to EPFO, ESI, and every formal financial institution.
The Trend: That is now changing structurally. India's Social Security Code 2020 formally included gig workers for the first time. Rajasthan became the first state to pass a dedicated Gig Worker Welfare Act in 2023. Karnataka and Telangana have active bills. SEBI's BRSR framework now requires listed gig platforms (Zomato, Swiggy) to report on gig worker benefits. EPFO is piloting an opt-in provident fund scheme for platform workers. For the first time in India's history, a Swiggy delivery executive can have a provident fund account.
The Drivers:
🛵 Workforce: 9 crore gig workers in India in 2026 — expected to cross 23 crore by 2030 — representing the largest uninsured, unbanked, under-credited workforce in the world
📊 Market Size: Every financial product a salaried employee takes for granted — health insurance, pension, vehicle loan, credit card, income insurance — needs to be rebuilt for gig workers with irregular income patterns. Total addressable market: ₹50,000 Cr
🏆 Concentration: Only 15-20 Indian startups are building financial products specifically for gig workers, despite EPFO inclusion and state welfare acts creating the regulatory foundation for the first time
🔥 The Account Aggregator framework + EPFO inclusion + UPI transaction history = the data infrastructure to underwrite India's 9 crore gig workers for financial products they've never had access to. The startup that builds the first bank, insurer, or pension for India's platform workforce will own a ₹50,000 Cr market with essentially no competition. That company doesn't exist yet.
Mad Hack

The Wrong Start: In 2008, Prashant Pitti and his brother Nishant started EaseMyTrip in Delhi with ₹50 lakh borrowed from family. Their competition: MakeMyTrip, which had raised $17M from SAIF Partners, and Cleartrip, which had raised $5M. Two brothers with a family loan, competing against VC-backed companies with marketing budgets orders of magnitude larger. Every industry observer wrote them off. In year one, they had no brand, no investor, and no way to out-advertise their rivals.
The Pivot: Instead of competing on marketing, Prashant made a pricing decision that every e-commerce expert at the time called commercially naive: EaseMyTrip would charge zero convenience fee. Every other portal charged ₹150-400 per booking — a meaningful revenue line that funded their marketing. EaseMyTrip kept ₹0. They earned only from airline commissions and hotel margins. The result: for a price-sensitive Indian traveler doing the math, EaseMyTrip was genuinely cheaper. Not by a gimmick — by a structural pricing choice. They couldn't afford advertising. So they built the product that advertised itself: the cheapest ticket.
The model also forced internal discipline. With no convenience fee revenue, every cost had to be earned back through genuine commission efficiency. The company was profitable every single year.
The Payoff: EaseMyTrip listed on NSE/BSE in March 2021. It was only the second Indian online travel company to list — after MakeMy Trip, which had raised $200M+ before going public. EaseMyTrip raised zero external capital before its IPO. The ₹50 lakh family loan became a ₹5,700 Cr public company. Profitable. Debt-free. Built without a single VC on the cap table.
🎯 The Builder Lesson: VC money solves some problems and creates others. If your market has customers who value price over brand, build the cheapest product and let the math do your marketing. EaseMyTrip didn't need ads. It needed the right number on the checkout page.
