The Slack category has been cooling over the past 6 years of tracked data. Total launches went from 4 in 2021 to 11 in 2026.
Average engagement ratio across all Slack launches sits at 0.22. Products above that threshold tend to serve a real, specific need. Products below it often entered a crowded market without sufficient differentiation.
We report what happened. We don't predict. Five years of data shows patterns, but markets surprise people for a living.
Three common reasons. The market consolidated around winners. The technology matured and stopped generating new startups. Or builder attention shifted to adjacent categories. Usually it's a combination.
Volume without engagement is saturation. Engagement without volume is opportunity. Check which one you're looking at.
Sum of all interest scores in the quarter divided by number of products. Simple average. We don't weight by category or product age.
Depends on what's declining. If volume drops but engagement rises, the market is maturing. That's often good for existing players. If both drop, the category may be dying. The quarterly breakdown on each page tells you which pattern you're seeing.
