Understand your customers

Where do I find people to interview when I have zero audience?

The short answer

Start with the person you already know who has the problem, then ask each interviewee for two intros. Go where the customer already hangs out, niche subreddits, WhatsApp/Slack groups, LinkedIn, industry meetups, and ask to learn, not to sell. Warm intros beat cold blasts every time.

Why we picked it This is the most direct answer to the second half of your question: where do you actually find these people. The piece walks through real channels (LinkedIn, Craigslist, niche communities, paid panels like User Interviews) and the tradeoffs of each when you have zero customers yet. It also stresses defining who you want to talk to first, and staying open as that picture shifts.

Why we picked it This is a straightforward, tactical rundown of where to source interviewees when your customer base is zero: relevant subreddits and Facebook groups, LinkedIn search by job title, and paid platforms as a last resort. It also covers how to word the outreach message itself, which is often the part founders get stuck on. Good to pair with the community-search essays above since it adds the actual message templates.

Why we picked it India does not have one launch button, so this is a useful starting point precisely because it shows ten real companies (Meesho, ShareChat, Dunzo, Redbus and more) reaching their first buyers through whatever channel actually sat where their users already were. Notice how few of them used a launch platform at all: WhatsApp groups, in-person workshops, travel agents, campus coupons, brand tie-ups. Read it as a menu of distribution moves to copy, not a formula.

How These 10 Indian Companies Got Their First 1000 Customers

From Medium by Harkirat Singh ~10 min read

  • Your first buyers come from the channel they already live in (WhatsApp groups, campuses, existing communities), not from a launch leaderboard.
  • Distribution in India is often physical and relationship-led (workshops, agents, partnerships), so plan for feet-on-ground reach, not just online posts.
  • Ten different companies used ten different first channels, which is the real lesson: pick the one channel that maps to your specific buyer and go deep.

Why we picked it When your personal network and community outreach genuinely run dry, this is the paid fallback: a recruiting panel of people willing to be interviewed for a fee, filterable by role, industry, and other criteria. It won't replace warm intros for depth, but it's a real way to fill gaps in a specific persona you can't otherwise reach. Use it to supplement, not substitute, the people you already know.

User Interviews

From userinterviews.com

  • Paid panels work well for narrow professional personas you can't reach personally
  • Screening questions matter more than volume, filter hard before you pay
  • Treat paid interviewees the same as warm ones, don't pitch, just listen
