Tech billionaire Reid Hoffman—best known as LinkedIn’s co-founder—is making headlines again, this time with a high-stakes bet on the future of brain health. Hoffman recently led a $12 million funding round for Sanmai Technologies, a stealth-mode startup merging artificial intelligence and ultrasound technology to tackle mental health and cognitive wellness.
Sanmai’s approach stands out in a crowded brain-tech field. Instead of invasive implants or daily medications, the company is developing a sub-$500, non-invasive headset that uses low-intensity focused ultrasound to stimulate targeted brain regions. This method, backed by years of clinical research, aims to address anxiety, depression, and cognitive decline without the side effects or risks associated with traditional treatments.
What sets Sanmai apart is its integration of AI. The headset’s AI assistant not only guides users through personalized therapy but also tackles technical challenges like skull distortion, adapting the treatment to each individual’s unique brain anatomy. This level of personalization is rare in the mental health tech space and could significantly improve outcomes.
While other brain-tech ventures—like Elon Musk’s Neuralink—are focused on surgical implants, Sanmai is betting on a lower-risk, consumer-friendly model. Their device is designed for home use, putting advanced mental health tools directly in the hands of everyday people. The company is already running clinical trials for generalized anxiety disorder in Sunnyvale, and is in discussions with the FDA to further validate its approach.
Hoffman’s investment signals a broader trend: tech billionaires are increasingly interested in funding innovations that push the boundaries of brain science. With over 20 companies now vying for leadership in this emerging market, Sanmai’s blend of science, safety, and AI could give it a real shot at reshaping how we think about—and treat—mental health.
For tech enthusiasts and investors, Sanmai’s story is a reminder of how rapidly the landscape is evolving. The combination of AI and ultrasound opens up new possibilities for non-invasive brain therapies, potentially making advanced mental health care more accessible and affordable. And with Hoffman’s backing, Sanmai has the momentum and credibility to make a real impact.
As the brain-tech race heats up, it’s worth watching how companies like Sanmai balance innovation with safety—and whether their consumer-first approach can truly revolutionize mental health care.
