What Neurosity does

Neurosity is a private neurotechnology company founded in 2018 and headquartered in Brooklyn, NY (with a San Francisco corporate address listed in its membership terms). The company's flagship product is the Crown, a non-invasive 8-channel EEG headset that captures microvolt-level brain signals (10-100 μV) and digitizes them at 256 Hz. A proprietary N3 chipset performs onboard preprocessing, including bandpass filtering and Independent Component Analysis for artifact removal, then calculates power spectral density across frequency bands to produce real-time focus and calm scores with sub-200ms latency. These metrics are exposed via JavaScript and Python SDKs, enabling a developer ecosystem to build brain-responsive applications on top of the device.

The product ecosystem pairs the Crown hardware with iOS and Android mobile apps, the NeuroAdaptive Meditation feature (which adapts in real time to the user's brain state), and a subscription Membership tier ($29.99/month or $299.99/year) that bundles exclusive focus modes, continuous updates, priority support, and the Neurosity Care Plan (device replacement at $299, free electrode replacement every six months, and annual repairs). Neurosity generates revenue through one-time hardware sales and recurring subscriptions, distributed primarily via direct-to-consumer e-commerce on neurosity.co and mobile app stores, supplemented by the Neurosity Professionals Program for resellers, researchers, and wellness practitioners.

The company serves three primary customer segments: individual knowledge workers seeking focus and productivity enhancement, software developers building brain-computer interface applications via the SDK, and healthcare/wellness professionals using the Crown for EEG data collection, cognitive tracking, and meditation training. Neurosity has raised approximately $4.98M in cumulative disclosed funding across multiple rounds from 2018 through 2022, with backers including Boost VC, Founders Inc., Hatcher+, Quake Capital Partners, Social Starts, and Myelin VC. The company is led by CEO AJ Keller, with Alex Castillo listed as co-founder, and operates with a small team of 1-10 employees.

Core offering

Neurosity manufactures and sells the Crown, a non-invasive 8-channel EEG headband brain-computer interface that measures microvolt-level brain signals and derives real-time focus and calm scores. The device works with the Neurosity mobile app and a paid Membership subscription to deliver neurofeedback, focus training, NeuroAdaptive Meditation, and developer SDK access for building brain-responsive applications.

Product overview

Neurosity offers a unified product ecosystem centered on the Crown EEG headband device. The Crown hardware works in conjunction with the Neurosity mobile app to provide real-time brainwave monitoring and neurofeedback. The company offers a subscription-based Membership service that adds premium features and device protection. Developers can build on the platform using JavaScript and Python SDKs. Key features include NeuroAdaptive Meditation for guided meditation, and the core focus-shift technology that measures and helps users improve their concentration through music-based neurofeedback.

Direct peers

• Muse: Muse makes a consumer EEG headband (Muse S) for meditation, sleep, and focus, with a subscription app — directly competing with Neurosity's Crown for the same knowledge worker and meditation customer. Both target focus and calm metrics through EEG neurofeedback.
• Emotiv: Emotiv builds multi-channel EEG headsets (Epoc X, Insight) with developer APIs and SDKs targeting research, wellness, and enterprise BCI use cases — a direct competitor to Neurosity's Crown with a more mature developer ecosystem.
• OpenBCI: OpenBCI manufactures open-source EEG hardware (Ultracortex, Galea) with developer-facing tools, directly comparable to Neurosity's Crown hardware + SDK positioning. Both serve developers, researchers, and hobbyists building brain-computer interface applications.
• Dreem: Dreem (formerly Rythm) makes a consumer EEG headband primarily for sleep, with a subscription app — adjacent to Neurosity's focus/meditation use case and competing for the same high-end consumer neurotech segment.
• NeuroSky: NeuroSky produces low-cost consumer EEG chipsets and headsets with developer APIs, historically a direct competitor to Neurosity's Crown in the consumer/developer EEG category.

Emerging players

• Neurable: Neurable develops EEG-based BCI technology for everyday use cases including focus and productivity (Enten headphones), overlapping with Neurosity's focus/meditation segment but with a different form factor.
• Calm: Calm is a leading meditation and mental wellness app that competes for the same end user (knowledge workers seeking focus, meditation, and stress reduction). Calm is software-only but is a substitute product for Neurosity's meditation features.
• Headspace: Headspace is a meditation and mental wellness app competing for the same meditation/focus customer as Neurosity. It is a substitute for the NeuroAdaptive Meditation feature in software form.

Broad incumbents

• Kernel: Kernel builds non-invasive brain measurement devices (Kernel Flow, Kernel CODEX) targeting neuroscience research and consumer cognitive applications. Well-funded and overlapping with Neurosity's brain-measurement and developer positioning.
• Apple: Apple's Health and Mindfulness features in watchOS and iOS, combined with potential future AirPods-based biometrics, represent a broad incumbent threat. Apple competes for the same attention/focus/wellness wallet share as Neurosity's consumer product.
