Which one pre-launch channel should I actually focus on instead of trying everything at once?
The short answer
Use Gabriel Weinberg's Bullseye method: list every channel you could try (Instagram, WhatsApp, a waitlist landing page, referrals, PR, offline pop-ups), run a cheap one-week test in 3-4 of them, then go all-in on whichever one actually produced signups or sales, not likes. Most first-time Indian D2C founders over-index on paid ads too early; the free channel that usually wins pre-launch is personal network plus Instagram, because trust travels faster than reach at zero brand recognition. Revisit the choice every few weeks - your core channel pre-launch is often not your core channel at scale.
