Hemispheric, a startup co-founded by former Apple engineer Gidi Littwin, has raised $52 million to develop AI models that diagnose cognitive disorders by analyzing non-invasive brain electrical activity.

Key Points

• Hemispheric secured $52 million in funding from venture capital firms and investors including Howard Morgan.
• The company trained its AI model using 250,000 hours of brain data collected from 100,000 volunteers in Asia, Tel Aviv, and Boston.
• Patients use a lightweight EEG headset and tablet app to record brain activity for 15-minute diagnostic sessions.
• The startup plans to submit its first product for PTSD diagnosis to the FDA in early 2025, targeting a 2027 public rollout.
• Future development includes creating proprietary brain scanners specifically designed to optimize data collection for deep learning models.

Why it Matters

This technology aims to transform mental health diagnostics from subjective behavioral assessments into objective, data-driven processes similar to standard blood tests. By providing a scalable and affordable diagnostic tool, Hemispheric could significantly improve early detection and treatment monitoring for conditions like Alzheimer’s, depression, and PTSD.
