Company overview

GrayMatters Health develops and markets Prism, a neurofeedback platform for mental healthcare clinics. Founded in 2018 by Oded Kraft, Rani Cohen and Shai Attia, the company lists headquarters in Haifa, Israel and U.S. headquarters in New York, New York, United States. Kraft is CEO and President; Kirk Thelander is Chief Commercial Officer.

Prism uses EEG signals and models developed from paired EEG and fMRI data to provide feedback through an interactive simulation. Patients practice personal mental strategies to influence the feedback. Its PTSD protocol received FDA 510(k) clearance in March 2023 as an adjunct to other interventions. The depression protocol is marketed separately as general wellness; its clinical pilot does not establish FDA clearance for depression.

The company announced a $10 million Series A led by Otsuka Medical Devices in 2022, a €2.5 million EIC grant that year and a separate EIC equity investment in 2023. U.S. commercial launch followed in January 2024. Provider publications from NYU Langone and Atrium Health document clinical use, while Prism360 and Prism Imagine expand clinic support and patient engagement. Revenue and current total funding were not verified.

Products & regulatory status How does MedTechIndex get this information?

Summary

Prism for PTSD is FDA-cleared under K222101 as an adjunct to standard care. The manufacturer’s general-wellness/exemption positioning for its Depression protocol is not a cleared depression-treatment indication. Prism Imagine’s visualization functions likewise do not automatically inherit the PTSD clearance. [2][12][15][17][1]

No matching FDA recall event was identified in the completed company/applicant, linked-identifier and product-name searches. [6][4]
