Holistic AI vs Warden AI

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

Holistic AI

Sales-quoted

Holistic AI is an enterprise AI governance platform for inventory, testing, monitoring, and regulatory mapping. Pricing is custom. There is no self-serve plan. Gartner has named it a Magic Quadrant Challenger in AI governance.

Where Holistic AI fits

  • Enterprises that must inventory and monitor HR and other AI systems under the EU AI Act
  • Risk teams that want red teaming and runtime monitoring in one vendor
  • Buyers who already talk Gartner MQ language for AI governance
  • Organizations mapping ISO 42001 or NIST AI RMF rather than a one-off NYC LL144 PDF

Warden AI

Sales-quoted

Warden AI sells independent HR AI bias audits and continuous assurance, including NYC LL144-style reports. Pricing is custom and scoped by tools, protected classes, and regulations. There is no public rate card.

Where Warden AI fits

  • NYC employers that need an independent LL144 bias audit, not a self-attestation
  • TA and legal teams running several automated employment decision tools
  • Companies that want continuous assurance after the first audit letter
  • EU and US employers mapping HR AI to the EU AI Act plus local employment law

Where they pull apart

Holistic AI

Stands out: The pitch is runtime agentic monitoring, red teaming, and 100-plus automated tests covering bias, hallucinations, and adversarial probes, mapped to the EU AI Act, NIST AI RMF, and ISO/IEC 42001.

Watch out: You will not see a price until a demo. The platform is built for organizations with a real AI inventory, not a first HR-AI audit spreadsheet. HR is one use case inside a broader GRC product.

Not the right fit for

  • HR teams that only need a one-time NYC LL144 bias audit PDF
  • SMBs that need a published price and a credit-card signup

Warden AI

Stands out: It is built as an independent auditor, not the vendor of the hiring model. Coverage is pitched across 14 to 15 protected classes, NYC LL144, and the EU AI Act, with ongoing assurance after the first report.

Watch out: Every engagement is scoped. You will not get a per-audit sticker price on the website. This is not a self-serve monitoring agent you can turn on overnight.

Not the right fit for

  • Teams that want an all-in-one GRC platform for every AI system in the company
  • Buyers who need a published price and a credit-card signup

Pros and cons

Holistic AI

  • EU AI Act, NIST AI RMF, and ISO 42001 mapping in one governance platform
  • Runtime monitoring and red teaming, not only a static model card
  • Positioned for enterprise AI inventories rather than a single HR tool
  • The vendor does not publish a price
  • Overkill if you only need an HR bias audit
  • No Capterra rating at 10-plus matching reviews

Warden AI

  • Independent auditor posture, not the hiring-tool vendor marking its own homework
  • NYC LL144-style reports plus EU AI Act language in the same specialist
  • Continuous assurance option after the initial audit
  • The vendor does not publish a price
  • Scoped for HR AI, not a full enterprise model inventory
  • No Capterra rating at 10-plus matching reviews
