The series runs 2026-04-03 through 2026-04-07, 4 posts so far, newest first below. The spread of publish dates is the cadence: the pillar is maintained, not a one-off essay collection.

How this pillar fits together
"Sector Deep Dives" is one of 10 topical series on the site, and its scope is deliberately narrow: sector-specific signal patterns, what github activity looks like in fintech, ai, cybersecurity, climate-tech, and other technical verticals. The keyword set (fintech startups, AI startup signals, cybersecurity startups, climate-tech engineering) marks the edges of that scope.
Each post in the grid above covers one slice of that scope, and together the 4 posts sequence from measurement (what the signals are) to workflow (what an investor does with them). Read them in publish order if you are new to the series; jump to the newest if you already run a sourcing stack.
The pillar interlocks with the dataset itself: every claim in the series cites the same weekly-recomputed methodology and the same machine-readable feeds, so the essays age as data updates rather than as opinions.
