What foc.us does
foc.us, operating through its legal entity Brain Control Co. Ltd., is a UK-based consumer neurotechnology company founded in 2012 that designs and sells transcranial Direct Current Stimulation (tDCS) headsets to individual consumers. Its product portfolio consists of two core hardware devices: the Focus V3, a premium $399 stimulator offering tDCS, tACS, tRNS, tPCS, and an exclusive tRCS mode with up to 4mA current output, and the Go Flow, a more portable 4mA tDCS device priced at $188 that includes a 0.75Hz slow oscillating tDCS mode. The underlying technology is firmware-based electrical brain stimulation, with the company positioning 4mA current output and multi-mode capability as differentiators versus other consumer tDCS offerings.
The company operates a direct-to-consumer e-commerce model through its own website (foc.us/store), with one-time hardware purchases as the sole disclosed revenue stream and no subscription or recurring component. Go-to-market is product-led, supplemented by content marketing (a blog focused on focus, concentration, ADHD, and neuroscience topics with posts continuing through at least July 2025), an email newsletter, and organic social media presence across Facebook, Twitter, Instagram, and YouTube. The target customer base consists of biohacking-oriented cognitive enhancement enthusiasts and at-home neurotechnology users seeking non-invasive brain stimulation outside clinical settings. Endorsements from a Transformative Tech Conference speaker (Dr. Jeffrey Martin) and a psychiatry and brain stimulation specialist (Dr. Rustin Berlow) are featured on the site. The company is privately held with 1–10 employees, was bootstrapped primarily through a small 2013 SOSV HAX seed round of $25,000, and shows no disclosed patents, certifications, regulatory clearances, or institutional backing.

foc.us competitors and assessment
Company assessmentEmerging players
- Emotiv: Emotiv produces consumer-grade EEG/BCI headsets (Epoc, Insight) that compete for the same self-optimization and brain-tech enthusiast customer wallet as foc.us. Different technology (sensing vs. stimulation) but strong overlap in persona, use cases, and content-marketing channels.
- Neurable: Neurable builds consumer brain-computer interface technology (e.g., Enten headband) for focus and productivity — directly adjacent to foc.us's focus/concentration value proposition. Competes for the same at-home neurotechnology user persona.
- Dreem: Dreem (formerly Rythm) developed consumer EEG-based sleep and focus headbands, targeting cognitive performance and wellness through brain monitoring. Adjacent value proposition (cognitive focus/sleep optimization) to foc.us, though Dreem is on the sensing rather than stimulation side.
- Muse (Interaxon): Muse sells consumer EEG brain-sensing headbands for meditation and focus, targeting the same cognitive-enhancement/biohacking demographic as foc.us. Adjacent category (EEG sensing vs. tDCS delivery) but overlapping customer base, retail channels, and content-marketing playbook.
Direct peers
- Caputron: Caputron sells consumer and clinical tDCS accessories, kits, and complete stimulation systems online. Directly comparable to foc.us on tDCS hardware sales, electrode kits, and biohacker/brain-stim community DTC channels.
- Neuroelectrics: Neuroelectrics makes Starstim and similar transcranial stimulation devices used in research and increasingly home settings, with multi-mode (tDCS/tACS/tRNS) capability. Closest technology-comparable peer to foc.us's multi-mode consumer offerings, though Neuroelectrics targets more clinical/research buyers.
- Halo Neuroscience: Founded in 2013, Halo built the Halo Sport, a consumer tDCS/tACS headset targeted at athletic performance and motor learning — directly comparable to foc.us's positioning of consumer-grade brain stimulation headsets for cognitive enhancement. Both companies pioneered consumer neurostimulation hardware in the same era and compete for the same biohacker/early-adopter wallet.
- Fisher Wallace: Fisher Wallace markets FDA-cleared CES (cranial electrotherapy stimulation) devices direct-to-consumer for sleep and mood. Comparable to foc.us as a small company selling consumer brain stimulation hardware DTC, though using CES rather than tDCS.
- Thync: Thync developed consumer transcranial stimulation wearables for mood and energy modulation using tDCS/tACS-like modalities, sold DTC. Overlaps with foc.us on consumer-grade electrical brain stimulation hardware targeting lifestyle/self-optimization use cases.
Broad incumbents
- Kernel: Kernel is a well-funded brain-interface company (Kernel Flow, Kernel Flux) operating in the broader consumer/professional neurotechnology space. Represents the larger, venture-backed entrant that threatens to consolidate the consumer neurotech category foc.us currently addresses.
