Tools that sit on the receiving end of demand - website chat that qualifies and books a visitor before a human ever joins, in-app signal tools that turn free-trial usage into a sales-ready account, and the newer wave of AI-SDR-for-inbound entrants trying to do both. The defining tension: this category has an unusually high mortality rate. Of the ten seed tools researched for this file, three (Pocus, Correlated, Toplyne) are confirmed dead or absorbed and two more (Drift, Ultimate.ai) are folded into an acquirer's platform rather than sold standalone - suggesting "PLG signal tool" and "chat widget" were never durable categories on their own, just features that bigger platforms eventually swallowed.
