How is AI company trending momentum measured?

Trending momentum is measured by comparing this week's metrics to last week's across four signals: package downloads (npm and PyPI), GitHub star growth, Hacker News mention frequency, and Reddit discussion volume. Companies with the highest percentage growth in each category are highlighted.

How often is the trending data updated?

Trending data is updated daily. Download counts sync from npm and PyPI registries, GitHub stars are fetched via the GitHub API, and community mentions are tracked across Hacker News and Reddit. Growth rates are calculated on a rolling 7-day window.

Adoption Cooling

Not all momentum is upward. Letta saw the largest download decrease this period (-80%). SambaNova had the largest HN mention decrease (-100%). Slowing momentum may reflect seasonal patterns, release cycles, or shifting developer attention - not necessarily product quality.
