The Scoring Methodology
Company scores derive from multiple data sources:
Financial Data: Funding amounts, valuations, and revenue estimates from press releases, SEC filings, and industry databases.
Market Signals: Press coverage, social media presence, job postings, and partnership announcements indicate market position and growth.
Technical Indicators: Research publications, benchmark performance, product releases, and developer adoption measure technical leadership.
Team Metrics: Leadership backgrounds, hiring velocity, and employee retention inform team quality scores.
Scores update continuously as new data emerges. A major funding round, a breakthrough product launch, or a key executive departure can shift scores within days.
Sector Classification
NeoSignal classifies companies into sectors reflecting their primary focus:
Hardware: Companies building AI compute infrastructure (NVIDIA, AMD, Intel)
Infra: Cloud platforms and infrastructure services (AWS, Google Cloud, Azure, CoreWeave)
Models: Foundation model developers (OpenAI, Anthropic, Google DeepMind, Meta AI)
Apps: Companies building applications on AI infrastructure (various startups)
Tooling: Developer tools, frameworks, and platforms (Hugging Face, Weights & Biases)
Services: AI consulting, integration, and managed services
Companies can span multiple sectors. Meta AI shows "Models" and "Tooling" tags—they build both foundation models (Llama) and developer frameworks (PyTorch).
Funding Stage Definitions
Public: Publicly traded on major exchanges. Shows stock ticker (NVDA, GOOGL, META, MSFT, AMZN).
Growth: Late-stage private companies with $500M+ raised, typically pre-IPO or approaching public listing.
Series D+: Companies with Series D or later funding, $200M-500M raised.
Series C: Mid-stage companies with Series C funding, typically $50M-200M raised.
Series A/B: Early-stage companies still establishing product-market fit.
The funding stage badge appears on every company card, enabling quick filtering by maturity level.
Real-World Use Cases
Competitive Intelligence: You're building in the AI space and need to understand the competitive landscape. The Companies directory shows who has the most funding (OpenAI at $17.3B), who's growing fastest (indicated by trend arrows), and which sectors are most crowded.
Investment Research: Evaluating AI companies for investment? Score breakdowns reveal strengths and weaknesses. A company with high Technical Leadership but low Funding Strength might be acquisition potential. High Growth Trajectory with moderate Market Position suggests a challenger worth watching.
Vendor Selection: Choosing between AI providers for your stack? Company profiles reveal staying power. A well-funded public company (NVIDIA) offers stability; a high-growth startup (Anthropic) offers innovation. Understand the tradeoffs before committing.
Partnership Evaluation: Considering a partnership with an AI company? The profile shows their ecosystem connections, financial health, and technical position. Related Components reveals what products they actually ship.
