Company profile
researched Aug 2026Anthriq, previously named Nexstem, develops infrastructure for acquiring, decoding and translating human biosignals such as EEG, ECG and EMG into inputs for technology that responds to human intent. The company positions its offering as a full-stack ecosystem combining hardware, software and data, intended to let developers prototype and deploy biosignal applications without building their own acquisition and processing stack.
Its announced product is Instinct, a 13-channel wireless EEG headset aimed at researchers, developers and neurotech builders, offered through a waitlist with shipping stated to begin in 2026. Alongside ready-to-use infrastructure, the company offers customized or co-created solutions for enterprise customers. It also describes an accumulating multimodal biosignal dataset that it intends to use to improve models across its ecosystem.
Business model
The company sells biosignal hardware and an accompanying software/data ecosystem to organizations building human-computer and brain-computer interface applications, and offers customized solutions developed jointly with enterprise customers alongside its off-the-shelf infrastructure.
Latest developments
In December 2025 the company announced Project Kinesis, a research project advancing human-machine interaction, and on January 13, 2026 it announced its rebranding from Nexstem to Anthriq. Its Instinct EEG headset had a waitlist of more than 500 people, with shipping stated to begin in 2026.
▸Full profile — market position, technology, go-to-market, history
Market position
Positions itself as foundational infrastructure for brain- and body-signal applications rather than an end-user application vendor, with practitioners citing deployability and usability outside controlled lab environments as its distinguishing focus.
The company emphasizes research-grade signal quality in a miniaturized, portable form factor, plug-and-play integration across hardware and software so customers can skip in-house R&D, and a proprietary multimodal biosignal dataset intended to compound over time.
Technology
The platform captures high-fidelity, programmable and portable biosignals including EEG, ECG and EMG, and pairs acquisition hardware with integrated software and data tooling. The flagship hardware is Instinct, a 13-channel wireless EEG headset. The company states its approach is grounded in applied neuroscience and validated through studies and pilots, and that it is assembling a growing multimodal biosignal dataset to strengthen its models.
Go-to-market
Direct sales and enterprise co-creation engagements, supported by a developer- and researcher-oriented product waitlist, downloadable whitepaper and comparative study, and third-party endorsements from clinicians and neurotech practitioners.
Researchers, developers and neurotech companies, plus enterprises across research and cognitive science, healthcare and neurorehabilitation, consumer wearables and wellness, education and learning, defense and aerospace, and gaming and immersive media.
History
The company operated as Nexstem before announcing on January 13, 2026 that it had renamed itself Anthriq, describing the change as reflecting a broader focus on human-aware technology. In December 2025 it announced Project Kinesis, a research project on human-machine interaction.
