Corporate.AI vs Middesk
Population-scale US entity monitoring at a flat annual rate — vs. per-verification fees that compound as your compliance volume grows.
The Core Difference
Population Scale
Corporate.AI pre-indexes all 27.5M US registered entities from official SOS filings. Search the entire registry instantly, no per-lookup fee.
Flat Annual Pricing
Starting at $499/yr for developers. No per-call overages. Run 10,000 verifications or 10 — the cost is the same. Middesk charges per verification at scale.
AI-Native API
Corporate.AI includes a Model Context Protocol (MCP) endpoint so ChatGPT, Claude, and custom AI agents can query the registry directly.

Which is Right for You?
Choose Corporate.AI if…
- You run compliance at scale — hundreds or thousands of entity checks per month
- You want population-level access: scan all registered entities in a state
- You're building an AI agent that needs to query the registry directly (MCP)
- You need developer-friendly API with flat, predictable annual pricing
- Your workflow is US-focused and you want direct SOS data, not aggregated
- You want a free evaluation tier before committing
Consider Middesk if…
- →You need all 50 states coverage today (Corporate.AI is expanding rapidly)
- →You need document verification beyond entity search (tax docs, W-9s)
- →Your volume is very low and per-check pricing works for your budget
- →You need bank account verification alongside entity verification
