The whole landscape
Every project on one board, placed by the waves it belongs to, or the September 2026 map as an image to keep.
How we found these waves
- The starting point
- Founder networking threads, quote posts and related posts, followed by project websites. The September 18 research reviewed 854 records: 851 unique projects and three duplicates.
- What we could learn
- 485 projects had enough evidence for the offering, audience and approach; 177 had a meaningful description with gaps; 189 lacked enough information. 440 projects fit the 70 recurring ideas in this edition.
- What a wave means
- A shared task, audience need or approach, checked against each project’s sources. It describes a pattern in this catalogue, not measured market growth. Some projects fit several waves; others have a distinct idea or need more information.
- Follow the evidence
- Open a wave for its criteria and source excerpts, then a project for the original sources and its builders. Counts above reflect the current published catalogue; the downloadable map records the research edition.
