How the Infrastructure Growth Score is built
The Infrastructure Growth Score (IGS) is a weekly 0–100 index that measures how aggressively an AI company is expanding its compute infrastructure — based entirely on public signals.
It is not a measure of company size, valuation, or model quality. A high score means a company is visibly mobilizing resources: hiring infra talent, provisioning new infrastructure, shipping code, and appearing in industry coverage. A low score means it is quiet across all four dimensions that week.
Open roles in infrastructure-adjacent engineering: compute, networking, storage, reliability, and platform engineering. Sourced from public job listings across the web.
New subdomains registered by the company, sourced from public Certificate Transparency logs. Bursts of new subdomains — particularly under infrastructure-suggestive patterns — are a leading indicator of active buildout. This signal receives the highest weight because it reflects committed capital and is the hardest to manufacture.
Public engineering output from the company's GitHub organization: repository growth and active development cadence. Lowest weight — public GitHub is an imperfect proxy for infrastructure spend, but provides a consistent, independent velocity signal.
Industry coverage of compute capacity announcements: data center builds, GPU procurement, power agreements, and construction permits. Sourced from specialist trade publications and classified for relevance using an AI model.
Each signal category produces a raw count for the week. Counts are normalized relative to all tracked companies — the company with the most activity in a category scores highest, companies with none score lowest. The four normalized sub-scores are combined into a single composite using fixed weights, with SSL/DNS receiving the largest share.
Scores are relative, not absolute. A company can gain or lose points week-over-week based on its own activity or on changes across the peer group.
All four signal categories are collected daily. The IGS composite is recomputed weekly. Score history is retained indefinitely for trend analysis.
IGS measures observable public signals only. Companies with private infrastructure (no public GitHub, no public job board, single domain) will score lower regardless of actual compute scale. The score is a momentum signal, not a census of GPU count or capital expenditure.
