Background and Funding

OpenAI disclosed an investment in Merge Labs, a neurotechnology venture co‑founded by Sam Altman. The funding round also includes private investment firm Bain Capital, video‑game developer Gabe Newell, and additional backers. The capital infusion is intended to support Merge Labs’ goal of building brain‑computer interfaces that avoid surgical implants. OpenAI will collaborate with the startup on scientific foundation models and other frontier tools, leveraging its AI expertise to accelerate the development of high‑bandwidth neural interfaces.

Technology Approach

Merge Labs differentiates itself from other brain‑computer interface companies by focusing on non‑invasive methods. Rather than using implanted electrodes, the company plans to employ ultrasound combined with molecular techniques to both read from and write to neurons. This approach interprets neural activity indirectly by detecting changes in blood flow, offering a potentially safer and more accessible pathway for interfacing with the brain.

The startup’s vision describes an interface that is “equal parts biology, device, and AI,” designed for broad accessibility. AI will play a central role in interpreting noisy neural signals, adapting to individual users, and delivering reliable performance. By integrating AI operating systems, Merge Labs hopes to create interfaces that can understand user intent and operate effectively despite limited signal quality.

Strategic Collaboration with OpenAI

OpenAI’s involvement goes beyond capital; the company will work with Merge Labs on scientific foundation models tailored for brain data. These models are expected to learn from large datasets of neural activity, enabling more intuitive and capable interfaces. The partnership reflects OpenAI’s broader interest in applying its artificial‑intelligence technologies to emerging hardware domains, potentially expanding the reach of AI‑driven tools into neurotechnology.

Potential Applications and Outlook

While Merge Labs has not disclosed specific product roadmaps, its parent nonprofit, Forest Neurotech, has shown interest in mental‑health disorders and brain‑injury research. Early safety trials of a miniaturized ultrasound device are already underway in the United Kingdom. The company’s non‑implantable strategy may position it to address a range of clinical and consumer use cases, from therapeutic interventions to enhanced human‑computer interaction.

Merge Labs joins a growing ecosystem of firms, including Elon Musk’s Neuralink and Synchron, that are exploring brain‑computer interfaces. However, its emphasis on ultrasound and molecular connectivity sets it apart from competitors that rely on implanted hardware. The collaboration with OpenAI could accelerate the translation of cutting‑edge AI research into practical neurotechnology, potentially reshaping how humans interact with computers.
