Gray Oncology Solutions

What Gray Oncology Solutions does

Gray Oncology Solutions is a Montréal-based healthcare technology company founded in 2019 that builds GrayOS, a Care Orchestration Platform designed to continuously reconcile patient demand against finite clinical capacity in oncology and adjacent complex care settings. GrayOS is deployed as an additive layer above existing Oncology Information Systems (MOSAIQ, ARIA, Elekta ONE) and Electronic Health Records (Epic, Cerner, DxCare, eClinibase), using constraint-based optimization grounded in operations research combined with machine learning for patient-flow forecasting and cancellation prediction. The platform is configured per institution across four rule families (protocol, capacity, operational, patient) and currently powers radiation therapy, systemic/infusion therapy, transplant and cellular therapy, and endoscopy/clinic workflows.

The company sells exclusively through a direct enterprise sales motion to large cancer centers and academic health systems, with the platform sold as a cloud-based annual SaaS subscription that includes integration, implementation, and ongoing support. Pricing is quote-based and not publicly disclosed. Customers are concentrated in flagship institutions including The Ottawa Hospital, CHUM, Princess Margaret Cancer Centre (UHN), Jewish General Hospital, Gustave Roussy, Mary Bird Perkins, Southlake, MUHC, CancerCare Manitoba, and Bismarck Cancer Center, with active deployments across Canada, the United States, France, and the United Kingdom.

GrayOS generates revenue from each customer's recurring subscription and is monetized through hospital-level enterprise contracts typically involving multi-year terms. The go-to-market relies on thought leadership (case studies, webinars), industry conference presence (AAPM, HLTH, ViVE, CancerX), and strategic distribution partnerships (notably Elekta for OIS channel access and HICSS for UK NHS). To date the company has disclosed approximately $1M CAD in equity funding from a 2021 angel round led by Anges Québec, a $2.9M CAD grant from Scale AI in 2023, accelerator participation with StartUp Health, NEXT AI, and CancerX, and reported 1,620 patients on-platform with a headcount of 1-10 employees.

Core offering

GrayOS is a Care Orchestration Platform sold as a cloud-based SaaS subscription to healthcare institutions. It is deployed as a software layer above existing OIS and EHR systems and uses operations research and AI-driven optimization algorithms to continuously balance patient demand against finite capacity (chairs, treatment machines, staff, hours) in real time. The platform automates scheduling and re-optimization across oncology departments and adjacent care settings such as endoscopy, transplant, and cellular therapy.

Product overview

Gray Oncology Solutions offers GrayOS, the industry's first Care Orchestration Platform (COP). GrayOS is a unified platform deployed as an operational layer above existing clinical systems (OIS and EHR) that continuously reconciles patient demand against finite capacity using advanced optimization algorithms grounded in operations research. The platform portfolio includes the core GrayOS platform, specialized modules for Systemic Therapy (infusion scheduling, chair utilization), Radiation Therapy (machine scheduling), Transplant and Cellular Therapy, and Endoscopy/Clinics operations. Each module shares the same optimization engine but is configured with specific protocol rules, capacity rules, operational rules, and patient rules for their respective care domain.

Scale indicators14 records

Recent moves7 records

Expansion highlights6 records

Direct peers

• LeanTaas: LeanTaas provides AI-driven scheduling and capacity optimization for hospitals, with deep penetration in operating rooms, infusion centers and inpatient flow — directly comparable to GrayOS's operations-research approach applied to oncology and other complex care pathways.
• Qventus: Qventus is an AI hospital operations platform that automates scheduling, discharge planning and capacity decisions across health systems, making it a direct comparable to GrayOS in terms of problem framing (real-time optimization on top of EHR) and buyer profile.
• Hospital IQ: Hospital IQ offers a healthcare operations platform focused on perioperative, inpatient and enterprise capacity optimization — comparable to GrayOS as a SaaS optimization layer deployed above existing clinical systems in hospitals and health systems.

Emerging players

• Notable: Notable provides intelligent automation for hospital workflows including scheduling, intake and revenue cycle — an emerging player with partial overlap to GrayOS's automation-of-operations thesis but broader in scope and less specialized in oncology.

Others

• LeanKit (Planview LeanKit): LeanKit delivers lean/agile workflow and kanban-based process management used in hospital operational improvement initiatives — adjacent rather than directly competing, but often used as a lightweight alternative for scheduling and process visibility.
• Tempus AI: Tempus applies AI to oncology data and clinical decision support rather than operational scheduling; it is thematically related (AI in oncology) but operates in an adjacent ecosystem rather than competing directly for the operations-research scheduling layer.

Broad incumbents

• Epic (Cadence): Epic's Cadence scheduling module is embedded in the dominant U.S. hospital EHR — GrayOS sits above Epic and integrates bidirectionally, making Epic both a critical integration partner and a broad incumbent whose own scheduling capabilities compete for the same problem.
• Elekta: Elekta's MOSAIQ and Elekta ONE OIS platforms dominate radiation oncology information systems; GrayOS is now a partner with Elekta, but Elekta also represents a broad incumbent whose own scheduling roadmap and installed base could absorb optimization functionality.
• Varian (Siemens Healthineers): Varian's ARIA oncology information system is the other dominant OIS in radiation oncology; GrayOS integrates bidirectionally with ARIA, positioning Varian as a broad incumbent whose product roadmap and pricing directly influence GrayOS's expansion path.
• Symplr: Symplr provides healthcare operations, credentialing and workforce management software sold to health systems — an adjacent broad incumbent with similar GTM motion (enterprise sales to hospital operations leaders) but a different functional focus.
