About
CalStack is booking software for teams that run sales and client calls in Google Meet, now rebuilt around the whole call, not just the booking. Before: AI-built booking flows with branching questions turn lead answers into talking points. During: a Google Meet side panel shows the agenda and the lead's answers. After: tag the outcome and AI writes the recap and next step. New free plan, no credit card.

A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
