Where to build: categories ranked by opportunity
Every category with at least ten businesses, ranked by how promising it is to build in: how many of its businesses one person could rebuild, how many are growing, how many are still an open field, and how many make $1K+/mo. Four shares, one score.
#
Category
Opportunity
The average of four shares, 0–100: businesses one person could rebuild (Yes verdicts), businesses growing (among those with a revenue trend), businesses in an open field (no moat yet), and businesses making $1K+/mo (among those reporting revenue). Equal weights.
Making $1K+ = share of businesses reporting revenue that make $1K or more a month.
What a working business makes, by category
Among businesses making $1K+/mo — the ones that are working — the typical monthly revenue in each category, and what the top quarter makes. A median shrugs off the giants; the floor leaves out side projects. Categories with at least ten such businesses.
Top quarter = the 75th percentile: one in four businesses at $1K+/mo in the category makes at least this.
Startup moats
9.4% of businesses run in an open field, with no moat yet — room for a better version. A moat is worth building toward: businesses with one earn 1.8× more than those without. The most common — switching costs and proprietary data — are things software can build.

Method: counts by verdict, moat, category and stack cover every business on Build Radar (668); revenue figures cover the 665 that report it, as the average of their last two full months or, where there is less history, current MRR. Verdicts, moats and stacks come from each business's profile. Medians are used throughout so a few very large businesses don't colour the picture for everyone else. Recomputed hourly; last run Oct 7, 2026.
