IDEs, frameworks, build systems, package managers, and the productivity layer engineers actually touch. A single page mapping who builds, who funds, and who leads in developer tools.
This hub aggregates the developer tools surface VC Deal Flow Signal tracks: 37 curated companies with public GitHub orgs, 33 venture funds whose published thesis covers developer tools, and notable engineering leaders whose work shapes the category. Developer tools have the cleanest commit-velocity signal because their entire product is the GitHub org. Acceleration shows up as repo creation pulse: new SDK languages, new integrations, new templates. Tech VPs scanning for tooling consolidation use this hub to map vendor density across their stack. Use it as a starting point for sourcing, diligence, or competitive scans.

In developer tools 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 37 curated developer tools 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.
33 funds in our /fund/ corpus publish developer tools 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 developer tools 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 developer tools startup we score, see /stage/[stage]/developer-tools — the scraped leaderboard.
