WhatsApp B2B Facebook and Google group discovery before paid ads
Find closed WhatsApp groups through Facebook and Google before buying traffic for a product whose ICP still needs sharper language.
Why this can grow a startup
The sourcing step is usually the hidden work. WhatsApp groups are less searchable than Reddit or LinkedIn, so the founder has to follow the messy trails: Facebook posts, Google results, niche community pages, and referrals from adjacent groups. The r/microsaas founder named Facebook and Google as discovery paths. This matters because paid ads are a poor teacher when the pitch is still fuzzy. Closed groups give the founder language, objections, and examples while also producing users. The tradeoff is time. It is not a forever channel for every product, but it can be a fast way to learn before ad spend hardens bad copy.
Company example
In replies, the founder said they generally found relevant WhatsApp groups through Facebook and Google, then joined groups where the niche conversation already matched the product.
