What Limina does
Limina, formerly Private AI and rebranded in March 2026, is a Toronto-headquartered data de-identification platform founded in 2019. The company's product detects, redacts, pseudonymizes, and replaces PII, PHI, and PCI across text, images, audio, and structured documents in 52 languages and 50+ entity types, using a proprietary linguistics-first AI approach designed to read context rather than match patterns. Limina's stated technical differentiators include on-premises or customer-VPC container deployment (so that data never leaves customer infrastructure), resilient handling of noisy inputs such as ASR errors and OCR mistakes, and integration with AWS, Azure, Snowflake, and NVIDIA NeMo. The platform is independently validated by Armilla AI (SwissRe-backed) and positioned for compliance with HIPAA, GDPR, CCPA, APPI, PIPEDA, and PCI-DSS requirements.
Limina sells into regulated industries — primarily healthcare, pharma, financial services, insurance, and contact centers — with named enterprise customers including Boehringer Ingelheim, Zurich Insurance, MUFG Bank, Providence Health, and Semalytix, alongside AI/technology customers such as Be My Eyes, Rilla, and GPTNL TNO. The go-to-market combines a self-serve freemium Starter API (up to 75 calls/day), a usage-based Professional tier, a Batch Processing service for one-time dataset jobs, and an Enterprise license with committed-volume pricing, dedicated Customer Success Manager, multi-region deployment, and custom SLA. Distribution is direct plus AWS and Azure Marketplace listings, with an authorized reseller channel. The company operates regional entities in Canada and Japan (Private AI Japan K.K.), holds ISO 27001 certification with SOC 2 Type II in progress, and is led by Co-Founder and Chairwoman Patricia Thaine. No revenue, funding totals, or detailed headcount are disclosed in the source data.

- Skyflow: Privacy API and data vault for PII/PHI/PCI tokenization, anonymization, and residency. Highly comparable to Limina in targeting regulated industries (healthcare, fintech) with developer-first privacy infrastructure.
- Protegrity: Enterprise data protection platform offering tokenization, encryption, and masking for PII and PHI across data warehouses. Comparable to Limina in regulated industries with on-prem and hybrid deployments.
Emerging players
- Tonic.ai: Synthetic data and de-identification platform for software teams building with production-like data. Comparable to Limina in serving AI/ML training data preparation use cases and developer-first deployment.
- Immuta: Data access and privacy governance platform with policy-based masking and de-identification on cloud data warehouses. Overlaps with Limina in Snowflake-centric privacy and access-governance workflows.
Broad incumbents
- Google Cloud DLP: Google Cloud's data loss prevention service offering PII detection and de-identification across structured and unstructured data. Competes with Limina for cloud-routed PII workloads in regulated enterprises.
