WhatsApp B2B niche group selection before blast
Join WhatsApp groups where the exact buyer already discusses tools and workflow problems before posting any launch message.
Why this can grow a startup
WhatsApp groups are small enough that a lazy pitch feels invasive fast. The 900-user example works because the founder did not treat WhatsApp as a cheaper email list. They looked for B2B groups where web agencies, digital marketers, founders, and freelancers were already talking about tools, referrals, and daily work. That meant the product's AI-discovery angle had context before the founder mentioned it. Ian's operator lens: in Southeast Asia and MENA, closed chat groups often carry more trust than public feeds. But the room has to match the job, or the intimacy becomes a liability.
