Share of new sites using Y Combinator Launches
Each dot is one launch day. Line is the 7-day rolling average; weekly averages before June 2026. Chart starts at first detection.
The shaded part of the chart is measured against a different set of sites. Until 8 July 2026 we only tracked launches from launch platforms; from that date we crawl the wider web as well. The share is a proportion of whatever we were tracking at the time, so it can step at that line without the technology itself changing. For a single continuous measure, switch to launch platforms.
