How we choose which AI companies to track and how we rank them
AI-Buzz tracks 262 independent AI companies. We select companies based on developer footprint: measurable signals that developers are actually using a company's tools, not valuation or funding raised.
A company qualifies for tracking if it meets at least one of these criteria:
We exclude big tech AI products (Google AI, Azure AI, etc.) from independent company rankings. They can be viewed separately via the "Include Big Tech" toggle on the companies page.
Companies are ranked by their developer footprint score, calculated as the sum of 30-day package downloads across both ecosystems:
Funding data is on every company page but does not factor into ranking. Downloads measure actual usage; funding measures investor confidence. See known limitations.

Rankings update daily as download data syncs. View the full list on the rankings page.
Companies are added manually. We find them through HN discussion, funding announcements, and developer community activity, then verify they build developer-facing AI products and meet at least one selection criterion above.

Companies are removed or reclassified when:
We never remove companies simply for having low download counts. Historical data is preserved for all tracked companies.
Each company has a primary domain based on its core product (e.g., Foundation Models, Code Generation, AI Agents) and optional secondary domains. Categories are updated as companies pivot. Browse by category on the companies directory.
