Cleerly

Cleerly's Top Stability & Growth Strengths

Investor Backing & Capital Strength: Recent capital raises, including a $223M Series C (2022) and an additional ~$106M Series C-II in December 2024, provide fuel for commercialization and R&D. This funding base underpins scaling efforts alongside regulatory and reimbursement tailwinds.

Market Expansion: Coverage has been formalized by major payers (UnitedHealthcare, Cigna, Aetna) and Category I CPT 75577 became effective January 1, 2026, reducing billing friction and widening access. Health-system deployments (e.g., MemorialCare) and payer policy integration (e.g., UHC prior-authorization materials) indicate growing operationalization across sites.

Strategic Partnerships: Partnerships with groups like Cardiac Care Alliance and integrations such as PowerScribe, along with OEM ties (e.g., Canon), extend channel reach and ease workflow adoption. Product rollouts including lesion-level reporting showcased at RSNA 2025 signal maturing go-to-market readiness.
