Compute, orchestration, inference, and the serving layer underneath the model providers. A single page mapping who builds, who funds, and who leads in ai infrastructure.
This hub aggregates the ai infrastructure surface VC Deal Flow Signal tracks: 13 curated companies with public GitHub orgs, 47 venture funds whose published thesis covers ai infrastructure, and notable engineering leaders whose work shapes the category. AI-infra companies have the most explicit engineering-acceleration signature of any sector: large-team coordination on actively shipped runtime, with weekly contributor influx tied to GPU-region rollouts and inference-API expansion. For Corp Dev teams at hyperscalers, AI-infra is the densest acquisition surface in 2026. Use it as a starting point for sourcing, diligence, or competitive scans.

In ai infrastructure we track four engineering-acceleration primitives across every monitored org: commit velocity (rolling 14-day vs trailing 12-week median), contributor influx (new committers in the trailing 4 weeks), repo creation pulse (new public repos shipped in the trailing 8 weeks), and language-bias drift (when a new primary language appears in production code). The six-signal panel published at /methodology is empirically tied to imminent fundraise probability — see SSRN paper 6606558.

We currently track 13 curated ai infrastructure companies whose GitHub orgs are self-published on their homepage, devrel blog, or hiring page. The full list with per-company signal pages is at /signal — filter by sector. We do not track private orgs, leaked employee data, or LinkedIn-inferred profiles.
47 funds in our /fund/ corpus publish ai infrastructure as part of their stated thesis. Each /fund/[slug] page is an independent summary of the fund's public thesis mapped against our engineering-acceleration signal panel. The corpus is not exhaustive — it is the seed set we built around Marcus 100 (Corp Dev, PE operating partners, non-engineer tech VPs).
Two workflows. (1) Source: weekly digest of ai infrastructure companies whose engineering acceleration matches your stage and check-size filters, delivered before competitive rounds form — see /firstlook. (2) Validate: given a deal already in your pipeline, retrieve the public engineering trajectory via the public MCP server at /api/v1 or the openapi.json at /api/openapi.json.
No. This is a curated seed corpus, not a Crunchbase-scale database. We add companies, funds, and founders deliberately when they meet our public-source threshold (self-published GitHub handle, public thesis, well-documented role). For the full open-source coverage of every ai infrastructure startup we score, see /stage/[stage]/ai-infra — the scraped leaderboard.
