Why we picked it
The single best thing ever written on customer conversations. It teaches you to ask about the customer's life and past behaviour, not your idea, so you can't be lied to. If a founder reads one thing before talking to a single customer, it's this.

by Rob Fitzpatrick
~130 pages
- Talk about their life, not your idea.
- Ask about specifics in the past, not opinions about the future.
- 'That's so cool, I'd totally buy it' is a compliment, not data, dig for commitment and evidence.

Why we picked it
This book documents how Indian and other emerging-market entrepreneurs build with severe resource constraints and turn adversity into design decisions. It's useful context, not a discovery method, for why a solution built for a Bengaluru office worker often doesn't survive contact with a Tier 2 or Tier 3 customer's actual constraints.

by Navi Radjou, Jaideep Prabhu, Simone Ahuja
- Seek opportunity in the very constraints, cost, infrastructure, income, that look like obstacles.
- Keep solutions simple enough to be used and repaired in the customer's real context.
- Flexibility to adapt a product as you learn beats a rigid, upfront-perfect plan.

Blume's annual report is the single best data-grounded read on what is actually happening in Indian internet and consumption, not what is trending on VC Twitter in San Francisco. It shows you adoption curves (UPI, quick commerce, ONDC, how few households actually shop online) so you can pressure-test whether a hyped trend has the demand base to land here. Treat it as a starting map of Indian reality, then judge your specific trend against it.
From
Blume Ventures
by Sajith Pai, Anurag Pagaria and team (Blume Ventures)
~180 charts
- Grounds trend-spotting in real Indian adoption data (income distribution, online-shopping penetration, UPI-native monetization) instead of imported hype.
- Indian startups are building a distinct playbook (micro-subscriptions on UPI Autopay, DPI rails) that has no clean US analogue, so copying a US trend directly often misses the real opportunity.
- A trend can be huge in raw numbers yet thin in monetizable demand: the report repeatedly separates users from paying users.

This is the primary-source study most vernacular-content stats you'll see online actually trace back to, so it's worth reading before you take anyone's word on the opportunity. It gives you the real numbers on how many Indians go online in a language other than English and how fast that base is growing. Treat the 2017 projections as directional, not gospel, but the core signal (most new internet users in India are not searching in English) has only strengthened since.

68-page PDF report
- Indian-language internet users were already outnumbering English users and were projected to be roughly 2.5x the English base, so English-only content quietly misses most of the market.
- About 9 in 10 new internet users coming online in India were expected to be regional-language users, which is where your untapped demand actually lives.
- Adoption is led by messaging, entertainment, news, and social, so the language your buyers read in is often not the language your English landing page speaks.

A concrete case study of a founder team that got out of the metro bubble and found a market (women resellers in smaller towns) that mainstream investors initially doubted. Useful as evidence that the willingness-to-pay and real-usage signal you need can come from unglamorous, overlooked segments.
From
YourStory
by YourStory
- Investors initially didn't believe non-metro, non-English-speaking users were a real market, the founders' own field observation proved otherwise.
- The underserved segment (Tier 2/3 resellers) had different needs than the urban e-commerce user everyone else was building for.
- Meeting users where they actually transact (WhatsApp, Facebook) beat building a new destination app.
