Gradient Health provides a medical imaging data platform giving AI researchers and healthcare companies access to de-identified radiology datasets for model training and validation.
Gradient Health is a healthcare data company founded in 2019 that operates a platform providing access to de-identified medical imaging data for AI development, research, and regulatory validation. The company partners with health systems and imaging centers to source, de-identify, and structure radiology datasets including X-rays, CT scans, MRI studies, and pathology images that AI developers need to train and validate clinical algorithms. Obtaining sufficient high-quality labeled medical imaging data has been one of the primary bottlenecks for AI medical imaging companies, and Gradient Health addresses this by creating a market for compliant data access. The company uses advanced de-identification techniques that go beyond HIPAA minimum requirements to ensure patient privacy while preserving the clinical detail that makes datasets useful for AI training. Gradient serves medical imaging AI companies, pharmaceutical companies conducting imaging biomarker research, and academic medical centers building AI models. The company has built relationships with health systems across the US and has assembled imaging datasets spanning millions of studies across diverse patient populations and imaging equipment types.
AI quality assurance with insurance-backed warranties from Swiss Re and Greenlight Re; EU AI Act compliance assessments backed by YC and reinsurance partners for high-risk AI deployments.
Armilla AI is a third-party AI quality assurance and warranty company that evaluates AI models for organizations deploying AI in regulated or high-stakes contexts — assessing models against EU AI Act and NIST AI Risk Management Framework requirements for risks including bias, hallucination, robustness failures, and adversarial vulnerabilities, then providing performance guarantees backed by insurance coverage from reinsurers Swiss Re, Greenlight Re, and Chaucer. Founded in Toronto, Canada, Armilla raised $6.81 million total including a C$4.5 million seed round in February 2024 from Mistral Venture Partners, MS&AD Ventures, Y Combinator, and its reinsurance partners.\n\nArmilla's model is unique in the AI governance market — rather than just providing compliance reports, Armilla backs its assessments with insurance warranty products. An enterprise deploying a third-party AI model can purchase an Armilla warranty that pays out if the model performs differently than assessed (fails on bias, accuracy, or robustness metrics), transferring AI performance risk to insurance markets that can price and distribute it. This insurance mechanism creates financial accountability for AI quality claims that audit reports alone don't provide.\n\nIn 2025, Armilla competes in the AI governance, risk, and compliance market with Credo AI, Arthur AI, and AI audit firms for enterprise AI risk assessment and compliance tools. The EU AI Act, fully applicable by August 2025 for high-risk AI systems, is driving enterprise compliance urgency — companies deploying AI in hiring, credit scoring, healthcare, and other regulated contexts need third-party conformity assessments. Armilla's insurance-backed warranty differentiates its offering from pure advisory competitors. The reinsurer backing (Swiss Re, Greenlight Re, Chaucer) provides both capital credibility and distribution through insurance broker channels. The 2025 strategy focuses on growing EU AI Act compliance assessments and expanding the warranty product coverage to more AI deployment use cases.
