How This Works

We track AI-related events from Reddit, arXiv, GitHub, company blogs, tech news, and other places where actual AI stuff happens. Not just press releases.

Scoring Formula

Score = Σ[(Innovation × 25% + Adoption × 25% + Market Impact × 20% + Media × 15% + Technical × 15%) × Time Decay]

Events are scored across 5 dimensions with time decay — recent activity matters more than old news. Sentiment and Hype/Reality are tracked separately as supplementary signals.

✓ What We Track

→ Product launches (actual demos)
→ Research papers (arXiv, journals)
→ GitHub activity (real code)
→ Partnerships (with substance)
→ Funding rounds (validated)
→ Hiring/layoffs (market signals)

✗ What We Ignore

→ Vague press releases
→ "Exploring AI" announcements
→ Repackaged old news
→ Executive quotes about AI
→ Generic "AI strategy" posts
→ Marketing without product

How We Rank AI Companies

Our proprietary algorithm analyzes real-time activity to rank companies by what they're actually doing, not what they're saying.

Event Collection

We monitor 222 verified sources including GitHub repositories, arXiv research papers, Reddit discussions, Hacker News, tech news sites, and product launches. Every 5 minutes, we scan for new activity.

Signal Processing

Our AI filters out marketing fluff, press release spam, and duplicate content. We focus on substantive events: code commits, research publications, product releases, and genuine community engagement.

Hype Detection

We compare marketing claims (blog posts, announcements) against actual technical activity (GitHub commits, research citations). Companies with high "Hype Gap" talk more than they ship.

Ranking Algorithm

Companies are scored across 5 dimensions, weighted by time-decayed event activity:

Score = Σ[(Innovation × 25% + Adoption × 25% + Market Impact × 20% + Media × 15% + Technical × 15%) × Time Decay]

• Innovation (25%): Product launches, breakthroughs, novel capabilities

• Adoption (25%): User growth, integrations, developer ecosystem

• Market Impact (20%): Funding, partnerships, acquisitions

• Media Attention (15%): Press coverage, community discussion

• Technical (15%): Research papers, benchmarks, open source

Sentiment and Hype/Reality are tracked separately as supplementary signals.

Real-Time Updates

Rankings refresh every 5 minutes. No human bias, no pay-for-ranking, no editorial interference. Pure algorithmic transparency.

Why trust our rankings? Unlike traditional lists compiled by journalists or based on funding rounds, our system is fully automated and measures real developer activity, research output, and community sentiment—the true signals of AI innovation.
