How Brex’s scores are calculated

The full audit trail, recomputed from the verdict data at build time through the same code that produced the leaderboard: verdict × quality × story weight per cell, cells sum to dimension scores, dimensions blend into the PA Score. Every number on the product page is reproducible from this page alone; for why the formula looks like this, see the methodology.

verdict factors: full ×1.0 · partial ×0.6 · disputed ×0.3 · none ×0.0 · n/a excluded from both sides · cell points = weight × quality × factor · cell max = weight × 10

PA Score29/100

Agent-ready 41.9 × 0.30 = 12.57

API quality 9.4 × 0.20 = 1.88

Openness 28.8 × 0.20 = 5.76

Built-in AI 31.2 × 0.15 = 4.68

Automation 26.3 × 0.15 = 3.94

(12.57 + 1.88 + 5.76 + 4.68 + 3.94) ÷ (0.30 + 0.20 + 0.20 + 0.15 + 0.15) = 28.84 ÷ 1.00 = 28.8

Scores are stored to 1 decimal; the product page’s pills round to whole numbers for display. Each dimension below shows the stories, verdicts, and cited evidence behind its number.
